The Loire (French pronunciation: [lwaʁ]; Occitan: Léger; Breton: Liger) is the longest river in France. With a length of 1,012 kilometres (629 mi), it drains an area of 117,054 km2 (45,195 sq mi), or more than a fifth of France's land area, and is the 170th longest river in the world.
It rises in the highlands of the southeastern quarter of the Massif Central in the Cévennes range (in the département of Ardèche) at 1,350 m (4,430 ft) near Mont Gerbier de Jonc; it flows northward for over 1,000 km (620 mi) through Nevers to Orléans, then west through Tours and Nantes until it reaches the Bay of Biscay (Atlantic Ocean) at St Nazaire. Its main tributaries include the Nièvre, Maine and the Erdre rivers on its right bank, and the Allier, Cher, Indre, Vienne, and the Sèvre Nantaise rivers to the left bank.
The Loire gives its name to six départements: Loire, Haute-Loire, Loire-Atlantique, Indre-et-Loire, Maine-et-Loire, and Saône-et-Loire. The central part of the Loire Valley was added to the World Heritage Sites list of UNESCO on December 2, 2000. The banks are characterized by vineyards and chateaux in the Loire Valley.
Historicity of the Loire River valley begins with the Middle Palaeolithic period of 90–40 kya (thousand years ago), followed by modern humans (about 30 kya), succeeded by the Neolithic period (6,000 to 4,500 BC), all of the recent Stone Age in Europe. Then came the Gauls, the historical tribes in the Loire during the Iron Age period 1500 to 500 BC; they made the Loire a major riverine trading route by 600 BC, establishing trade with the Greeks on the Mediterranean coast. Gallic rule ended in the valley in 56 BC when Julius Caesar conquered the adjacent provinces for Rome. Christianity made entry into this valley from 3rd century AD with many saints converting the pagans. This was also the time when wineries came to be established in the valley.
The Loire Valley has been called the "Garden of France" and is studded with over a thousand chateaux, each with distinct architectural embellishments covering a wide range of variations, from the early medieval to the late Renaissance periods. They were originally created as feudal strongholds, over centuries past, in the strategic divide between southern and northern France; now many are privately owned.

The name "Loire" comes from Latin Liger, which is itself a transcription of the native Gaulish (Celtic) name of the river. The Gaulish name comes from the Gaulish word liga, which means "silt, sediment, deposit, alluvium", a word that gave French lie, as in sur lie, which in turn gave English lees. Liga comes from the Proto-Indo-European root *legh-, meaning "to lie, lay", which gave many words in English, such as to lie, to lay, ledge, law, etc.
Studies of the palaeogeography of the region suggest that in the pathogeolic the palaeo-Loire continued its northward flow and joined the Seine, while the lower Loire found its source upstream of Orléans in the region of Gien, flowing westward along the present course. At a certain point during the long history of uplift in the Paris Basin, the lower, Atlantic Loire captured the "palaeo-Loire" or Loire séquanaise ("Loire-Seine"), producing the present river. The former bed of the Loire séquanaise is occupied by the Loing.
The Loire Valley has been inhabited since the Middle Palaeolithic period from 40–90 ka. Neanderthal man made boats out of tree trunks and stone tools and navigated the river. Modern man inhabited the Loire valley around 30 ka. By around 5000 to 4000 BC they began clearing forests along the river edges and cultivating the lands and rearing livestock. They built megaliths to worship the dead, especially from around 3500 BC. The Gauls arrived in the valley between 1500 and 500 BC and the Carnutes settled in Cenabum in what is now Orléans and built a bridge over the river. By 600 BC the Loire had already become a very important trading route between the Celts and the Greeks and would become one of the great highways of France for over 2000 years. The Phoenicians and Greeks had used pack horses to transport goods from Lyon to the Loire to get from the Mediterranean basin to the Atlantic coast.
Ancient Rome and the Vikings
During the Roman period, they successfully subdued the Gauls in 52 BC and began developing Cenabum which they named Aurelianis and also began building the city of Caesarodunum, now Tours, from AD 1. The Romans used the Loire as far as Roanne, only around 150 km (93 mi) from the source. After AD 16, the Loire river valley became part of the Roman province of Aquitania, with its capital at Avaricum. From the 3rd century, Christianity spread through the river basin and many religious figures began cultivating vineyards along the river banks. In the 5th century, the Roman Empire declined and the Franks and the Alemanni came to the area from the east. Following this there was ongoing belligerence between the Franks and the Visigoths. In the 9th century, the Vikings began invading the west coast of France and used long ships to navigate the Loire. In 853 they ruined Tours and its famous abbey, later ruining Angers in 854 and 872. In 877 Charles the Bald died, marking an end to the Carolingian dynasty. After considerable conflict in the region, in 898 Foulques le Roux of Anjou gained power.
During the Hundred Years' War from 1337 to 1453, the Loire River marked the border between the French and the English. One-third of the inhabitants died from the Black Death of 1348–9. The English defeated the French in 1356 and Aquitaine became English in 1360. In 1429, Joan of Arc persuaded Charles VII to banish the English from the country. Her successful relief of the siege of Orléans, on the Loire, was the turning point of the war. In 1477, the first printing press in France was established in Angers, and around this time the Chateau de Langeais was built. During the reign of François I from 1515 to 1547, the Italian Renaissance had a profound impact upon the region, and became deeply ingrained in the architecture and culture of the region, particularly among the elite and their chateaus. In the 1530s, the Reformation ideas reached the Loire valley and in 1560 Catholics drowned several hundred Protestants in the river. During the Wars of Religion from 1562 to 1598, Orléans served as a prominent stronghold for the Huguenots but in 1568 Orléans Cathedral was blown up by the Protestants. In 1572 the St. Bartholomew's Day massacre saw some 3000 Huguenots slaughtered in Paris, followed by the drowning of hundreds of them by the Catholics in the Loire River.
For centuries attempts were made to keep a navigable channel open by the use of wooden embankments and dredging. River traffic increased gradually, with a toll system being used in medieval times. Today some of these toll bridges still remain, dated to over 800 years. During the 17th century, Jean-Baptiste Colbert instituted stone retaining walls and quays from Roanne to Nantes which helped make the river more reliable, but navigation was frequently stopped by flood and drought. In 1707, floods were said to have drowned 50,000 people, with the water rising more than 3 m (9.8 ft) in two hours in Orléans. A typical passenger timetable from Orléans to Nantes took eight days, with the upstream journey against the flow taking fourteen.
Steam-driven passenger boats appeared soon after the beginning of the 19th century plying the river between Nantes and Orléans; by 1843, 70,000 passengers were being carried annually in the Lower Loire and 37,000 in the Upper Loire. However with the introduction of the railway in the 1840s trade on the river steadily declined and proposals to build a fully navigable river up to Briare came to nothing. The opening of the Canal latéral à la Loire in 1838 enabled navigation between Digoin and Briare to continue, but the river level crossing at Briare remained a problem until the construction of the Briare aqueduct in 1896, which at 662.69 metres was the longest such structure in the world for quite some time.
The Canal de Roanne à Digoin was also opened in 1838 and was nearly closed in 1971 but still provides navigation further up the Loire valley to Digoin. However the 261 km (162 mi) Canal de Berry, a narrow canal with locks only 2.7 m (8.9 ft) wide, which was opened in 1820s and connected the Canal latéral à la Loire at Marseilles-lès-Aubigny to the Cher River at Noyers and back into the Loire near Tours, was closed in 1955. Today the river is only officially navigable as far as Bouchemaine, where the Maine joins it near Angers, together with a short stretch much further upstream at Decize, where a river level crossing from the Canal latéral à la Loire connects to the Canal du Nivernais.
The monarchy of France ruled in the Loire Valley for several centuries and as a result it got the title "The Valley of Kings". Starting with the Gauls, followed by the Romans, then the Frankish Dynasty who were succeeded by the kings of France who ruled from late 14th century till the French Revolution and all of rulers were responsible for the development of the valley. The chronology of the rulers is presented in the table below.

The source of the river lies in the eastern Massif Central, in springs to the south side of Mont Gerbier de Jonc at . This lies in the north-eastern part of the southern Cévennes highlands, in the Ardèche commune of Sainte-Eulalie of southeastern France. It is originally a mere trickle of water located at 1,408 m (4,619 ft) above sea level. The presence of a groundwater under Mont Gerbier de Jonc gives rise to multiple sources, three of them located at the foot of Mount have been highlighted as river sources. The three streams converge to form the Loire, which descends the valley south of Mount through the village of Sainte-Eulalie itself.
The Loire River changed its course, due to tectonic deformations, from the original outfall into the English Channel to its new outfall into the Atlantic Ocean thereby creating the presently seen narrow terrain of gorges, the Loire Valley with alluvium formations and the long stretch of beaches along the Atlantic Ocean. The river can be divided into three main zones; the Upper Loire which is the area from the source to the confluence with the Allier, the middle Loire Valley which is the area from the Allier to the confluence with the Maine, about 280 km (170 mi), and the Lower Loire which is the area from Maine to the estuary. In the upper basin the river flows through a narrow, incised valley, marked by gorges and forests on the edges and a distinct low population. In the intermediate section, the alluvial plain broadens and the river meanders and forks into multi-channels. River flow is particularly high in the river area near Roanne and Vichy up to the confluence with the Allier. In the middle section of the river in the Loire Valley, numerous dikes built between the 12th and 19th century exist, providing mitigation against flooding. In this section the river is relatively straight, except for the area near Orléans and numerous sand banks and islands exist. The lower course of the river is characterized by wetlands and fens, which are of major importance to conservationists given that they from unique habitats for migratory birds.
The Loire flows roughly northward through Roanne and Nevers to Orléans and thereafter westward through Tours to Nantes, where it forms an estuary. It flows into the Atlantic Ocean at between Saint-Nazaire and Saint-Brevin-les-Pins, connected by a bridge over the river near its mouth. Several départements of France were named after the Loire. The Loire flows through the following départements and towns: Ardèche, Haute-Loire: Le Puy-en-Velay, Loire: Feurs, Roanne, Saône-et-Loire: Digoin, Allier, Nièvre: Decize, Nevers, La Charité-sur-Loire, Cosne-Cours-sur-Loire, Cher: Sancerre, Loiret: Briare, Gien, Orléans, Loir-et-Cher: Blois, Indre-et-Loire: Amboise, Tours, Maine-et-Loire: Saumur, Loire-Atlantique: Ancenis, Nantes, Saint-Nazaire.
The Loire Valley in the Loire River basin, is a 300 km (190 mi) stretch in the western reach of the river starting with Orléans and terminating at Nantes, 56 km (35 mi) short of the Loire estuary and the Atlantic Ocean. The tidal stretch of the river extends to a length of 60 km (37 mi) and a width of 3 km (1.9 mi), which has oil refineries, the port of St-Nazaire and 40,000 hectares (99,000 acres) of wetland whose formation is dated to 7500 BC (caused by inundation by sea waters on the northern bank of the estuary), and the beaches of Le Croisic and La Baule along the coast line.
Its main tributaries include the Maine, Nièvre and the Erdre rivers on its right bank, and the Allier, Cher, Indre, Vienne, and the Sèvre Nantaise rivers on the left bank. The largest tributary of the river is the Allier River, 410 km (250 mi) in length, which joins the Loire near the town of Nevers at . Downstream of Nevers lies the Loire Valley, a UNESCO World Heritage Site due to its fine assortment of castles. The second longest tributary is the 372 km (231 mi) Vienne River which joins the Loire at Candes-Saint-Martin at , followed by the 367.5 km (228.4 mi) Cher River, which joins the Loire near Cinq-Mars-la-Pile at and the 287 km (178 mi) Indre River, which joins the Loire near Néman at .

The geological formations in the Loire River basin has been dictated by two sets of formations namely, the basement domain and the domain of sedimentary formations; the former domain primarily consists of metamorphic and siliceous fragmented rocks with ground water in fissures, and the latter formation of sedimentary rocks consists of limestone and carbonaceous rocks rich in ground water aquifers. Rock outcrops of granites or basalts are also seen exposed in the river bed in several stretches.
The middle stretches of the river has many limestone caves which were inhabited in the prehistoric era; the caves are several types of limestone formations, namely tuffeau (a porous type of chalk, not to be confused with tufa) and Falun (formed 12 million years ago). The coastal zone shows hard dark stones, granite, schists and thick soil mantle.
Discharge and flood regulation
The river has a discharge rate of 863 m3/s (30,500 cu ft/s), which is an average over the period 1967–2008. The discharge rate varies strongly along the river, with roughly 350 m3/s (12,000 cu ft/s) at Orléans and 900 m3/s (32,000 cu ft/s) at the mouth. It also depends strongly on the season, and the flow of only 10 m3/s (350 cu ft/s) is not uncommon in August–September near Orléans. During floods, which usually occur in February–March but also in other periods, the flow sometimes exceeds 2,000 m3/s (71,000 cu ft/s) for the Upper Loire and 8,000 m3/s (280,000 cu ft/s) in Lower Loire. The most serious floods occurred in 1856, 1866 and 1911. Unlike most other rivers in western Europe, there are very few dams or locks creating obstacles to its natural flow. The flow is partly regulated by three dams: Grangent Dam and Villerest Dam on the Loire and Naussac Dam on the Allier River. The Villerest dam, built in 1985 a few kilometres south of Roanne, has played a key-role in preventing recent flooding. As a result, the Loire is a very popular river for boating excursions, flowing through a pastoral countryside, past limestone cliffs and historic castles. Four nuclear power plants are located on the river: Belleville, Chinon, Dampierre and Saint-Laurent.
The French language adjective ligérien is derived from the name of the Loire river, as in le climat ligérien ("the climate of the Loire Valley"). The climate is considered the most pleasant of northern France, with warmer winters and, more generally, fewer extremes in temperatures, rarely exceeding 38 °C (100 °F). It is identified as temperate maritime climate, and is characterised by the lack of dry seasons and by heavy rains and snowfall in winter, especially in the upper streams. The number of sunny hours per year varies between 1400 and 2200 and increases from northwest to southeast.
The Loire Valley, in particular, enjoys a salubrious temperate climate. The region experiences a rainfall of 690 mm along the coast and 648 mm inland.
The Centre region of the Loire River valley accounts for the largest forest in France, the "Forêt d'Orléans", covering an area of 38,234 ha, and the 5,440 ha forested park known as the "Foret de Chambord". Other vegetation in the valley, mostly under private control, consists of tree species of oak, beech and pine. In the marshy lands, ash, alder and willows are grown with duckweed providing the needed natural fertilizing effect. The Atlantic coast is home to several aquatic herbs, the important species is Salicornia, which is used as a culinary ingredient on account of its diuretic value. Greeks introduced vines. Romans introduced melons, apples, cherries, quinces and pears during the Middle Ages, apart from extracting saffron from purple crocus species in the Orléans. Reine claude (Prunus domestica italica) tree species was planted in the gardens of the Château. Asparagus was also brought from northwestern France.
With more than 100 algae species, the Loire has the highest phytoplankton diversity among French rivers. The most abundant are diatoms and green algae (about 15% by mass) which mostly occur in the lower reaches. Their total mass is low when the river flow exceeds 800 m3/s and become significant at the flows of 300 m3/s or lower which occur in summer. With decreasing flow, first species which appear are singe-cell diatoms such as Cyclostephanos invisitatus, C. meneghiniana, S. Hantzschii and Thalassiosira pseudonana. They are then joined by multicelluar forms including Fragilaria crotonensis, Nitzschia fruticosa and Skeletonema potamos, as well as green algae which form star-shaped or prostrate colonies. Whereas the total biomass is low in the upper reaches, the biodiversity is high, with more than 250 taxa at Orléans. At high flows and in the upper reaches the fraction of the green algae decrease and the phytoplankton is dominated by diatoms. Heterotrophic bacteria are represented by cocci (49%), rods (35%), colonies (12%) and filaments (4%) with a total density of up to 1.4×1010 cells/L.
Nearly every freshwater fish species of France can be found in the Loire river basin, that is about 57 species from 20 families. Many of them are migratory, with 11 species ascending the river for spawning. The most common species are the Atlantic salmon (Salmo salar), sea trout (Salmo trutta), shads (Alosa alosa and Alosa fallax), sea lamprey (Petromyzon marinus) European river lamprey (Lampetra fluviatilis) and smelt (Osmerus eperlanus). The European eel (Anguilla anguilla) is common in the upper streams, whereas the flounder (Platichtys flesus) and flathead mullet (Mugil spp.) tend to stay near the river mouth. The tributaries host brown trout (Salmo trutta), European bullhead (Cottus gobio), European brook lamprey (Lampetra planeri), zander (Sander lucioperca), nase (Chondrostoma nasus and C. toxostoma) and wels catfish (Siluris glanis). The endangered species include grayling (Thymallus thymallus), burbot (Lota lota) and bitterling (Rhodeus sericeus) and the on-native species are represented by the rock bass (Ambloplites rupestris).
Although only one native fish species become extinct in the Loire river, namely the European sea sturgeon (Acipenser sturio) in the 1940s, the fish population is declining, mostly due to the decrease in the spawning areas. The latter are mostly affected by the industrial pollution, construction of dams and drainage of oxbows and swamps. The loss of spawning grounds mostly affects the pike (Esox lucius), which is the major predator of the Loire, as well as eel, carp, rudd and salmon. The great Loire salmon, a subspecies of Atlantic salmon, is regarded as the symbolic fish of the river. Its population has decreased from about 100,000 in the 19th century to below 100 in the 1990s that resulted in the adoption of a total ban of salmon fishing in the Loire basin in 1984. A salmon restoration program was initiated in the 1980s and included such as measures as removal of two obsolete hydroelectric dams and introduction of juvenile stock. As a result, the salmon population increased to about 500 in 2005.
Most amphibians of the Loire are found in the slow flow areas near the delta, especially in the floodplain, marshes and oxbows. They are dominated by the fire salamander (Salamandra salamandra), frogs and toads. The toads include Bufo bufo, Alytes obstetricans, Bombina variegata, Bufo calamita, Pelobates fuscus and Pelobates cultripes. The frogs are represented by the Parsley frog (Pelodites punctatus), European tree frog (Hyla arborea), Common Frog (Rana temporaria), Agile Frog (R. dalmatina), Edible Frog (R. esculenta), Perez's Frog (R. perezi), marsh frog (R. ridubunda) and Pool Frog (R. lessonae). Newts of the Loire include the Marbled Newt (Triturus marmoratus), Smooth Newt (T. vulgaris), Alpine Newt (T. alpestris) and Palmate Newt (T. helveticus).
The Loire River hosts about 64% of nesting bird species of France, that is 164 species, of which 54 are water birds, 44 species are common for managed forests, 41 to natural forests, 13 to open and 12 to rocky areas. This avifauna has been rather stable, at least between the 1980s and 2000s, with significant abundance variations observed only for 17 species. Of those, five species were growing in population, four declining, and other eight were fluctuating. Some of these variations had a global nature, such as the expansion of the Mediterranean gull in Europe.
The Loire has been described as "constantly under threat of losing its status as the last wild river in France". The reason for this is that due to its sheer length and possibility of extensive navigation, which severely limits the scope of river conservation. The Federation, a member of the IUCN since 1970, has been very important in the campaign to save the Loire river system from development.
In 1986, the French government, the Loire-Brittany Water Agency and the EPALA settled an agreement on flood prevention and water storage programme in the basin, involving construction of four large dams, one on the Loire itself and three on the Allier and Cher. The French government proposed a construction of a dam at Serre de la Fare on the upper Loire River which would have been an environmental catastrophe, as it would have inundated some 20 km (12 mi) of pristine gorges. As a result the WWF and other NGOs established the Loire Vivante (Living Loire) network in 1988 to oppose the Serre de la Fare dam scheme and arranged an initial meeting with the French Minister of the Environment. The French government initially rejected the conservation concerns and in 1989 gave the dam projects the green light. This sparked public demonstrations by the WWF and conservation groups. In 1990, Loire Vivante met with the French Prime Minister and the government, this time successfully as the government later demanded that the EPALA embark upon major reforms in its approach to managing the river. Due to extensive lobbying, the proposal and the other dam proposals were eventually rejected in the 1990s and the Serre de la Fare area has since been protected as a ‘Natura 2000’ site under European Union environmental legislation.
The WWF were particularly important in changing the perception of the French authorities in support for dam building to environmental protection and sustainable management of its river basin. In 1992, they aided the ‘Loire Nature’ project, which received funds of some $US 9 million under the EU's ‘LIFE’ programme until 1999, embarking upon restoration to the river's ecosystems and wildlife. That year, the Upper Loire Valley Farmers Association was also established through a partnership between SOS Loire Vivante and a farmers’ union to promote sustainable rural tourism. The French government adopted the Natural Loire River Plan (Plan Loire Grandeur Nature) in January 1994, initiating the decommissioning of three dams on the river. The final dam was decommissioned by Électricité de France at a cost of 7 million francs in 1998. The basis of the decision was that the economic benefits of the dams did not outweigh their significant ecological impacts, so the intention was to restore the riverine ecosystems and replenish great Loire salmon stocks. The Loire is unique in this respect as the Atlantic Salmon can swim as far as 900 km (560 mi) up the river and spawn in the upper reaches of the Allier River. The French government undertook this major plan, chiefly because pollution and overfishing had reduced approximately 100,000 salmon migrating annually to their spawning grounds in the headwaters of the Loire and its tributaries to just 67 salmon in 1996 on the upper Allier.
The WWF, BirdLife International, and local conservation bodies have also made considerable efforts to improve the conservation of the Loire estuary and its surroundings, given that they are unique habitats for migrating birds. The estuary and its shoreline are also important for fishing, shellfish farming and tourism. The major commercial port at Nantes has caused severe damage to the ecosystem of the Loire estuary. In 2002, the WWF aided a second Loire Nature project and expanded its cope to the entire basin, addressing some 4,500 hectares (11,000 acres) of land under a budget of US$18 million, mainly funded by government and public bodies, such as the Établissement Publique Loire (EPL), a public institution which had formerly advocated large-scale dam projects on the river.

The Loire Valley (French: Vallée de la Loire) lies in the middle stretch of the river and lasts for about 280 km (170 mi) and comprising an area of roughly 800 km2 (310 sq mi). It is also known as the Garden of France due to the abundance of vineyards, fruit orchards, artichoke, asparagus and cherry fields which line the banks of the river. and the Cradle of the French Language. It is also noteworthy for the quality of its architectural heritage, in its historic towns such as Amboise, Angers, Blois, Chinon, Nantes, Orléans, Saumur, and Tours, but in particular for its castles, such as the Châteaux d'Amboise, Château de Chambord, château d'Ussé, Château de Villandry and Chenonceau and more particularly its many cultural monuments, which illustrate the ideals of the Renaissance and the Age of the Enlightenment on western European thought and design.
On December 2, 2000, UNESCO added the central part of the Loire River valley, between Maine and Sully-sur-Loire, to its list of World Heritage Sites. In choosing this area that includes the French départements of Loiret, Loir-et-Cher, Indre-et-Loire, and Maine-et-Loire, the committee said that the Loire Valley is: "an exceptional cultural landscape, of great beauty, comprised of historic cities and villages, great architectural monuments – the Châteaux – and lands that have been cultivated and shaped by centuries of interaction between local populations and their physical environment, in particular the Loire itself."
Architectural edifices were created in Loire valley from the 10th century onwards with the defensive fortress like structures called the "keeps" or "donjons" built between 987 and 1040 AD by Anjou Count Foulques Nerra of Anjou (the Falcon). However, one of the oldest such structures in France is the Donjon de Foulques Nerra of 944 AD vintage.
This style was replaced by the religious architectural style in the 12 and 14th century when the impregnable château fortresses were built on top of rocky hills; one of the impressive fortresses of this type is the Château de Andrex, which has 17 gruesome towers. This was followed by aesthetically built Châteaus (to also function as residential units), which substituted the quadrangular lay out of the "keep". However, the exterior defensive structures, in the form of portcullis and moats surrounding the thick walls of the Château forts were retained. There was further refinement in the design of the châteaus in the 15th century before the Baroque style came into prominence with decorative and elegantly designed interiors and which became fashionable from the 16th to end of 18th century.
The Baroque style artists who created some of the exquisite château structures were: The Parisian, François Mansart (1598–1662) whose classical symmetrical design is seen in the Château de Blois; Jacquis Boogier (1635) of Blois whose classical design is the Château de Cheverny; Guillaume Bautru remodelled the Château de Serrant (at the extreme western end of the valley). In the 17th century, there was feverish pace in the design the château for introducing exotic styles; a notable structure of this period is the Pagode de Chanteloup at Amboise, which was built between 1773 and 1778.
The Neoclassical architectural style, was a revival of Classical style of architecture, which emerged in the mid 18th century; one such notable structure is the Château de Menars built by Jacques Ange Gabriel (1698–1782) who was the royal architect in the court of Louis XV (1715–74). This style was perpetuated during the reign of Louis XVI (1774–92) but with more refinements; one such refined château seen close to Angers is the Château de Montgeoffroy. Furnishings inside the châteaus also witnessed changes to suit the living styles of its occupants. Gardens, both ornamental fountains, foot paths flower beds and tended grass) and kitchen type (to grow vegetables), also accentuated the opulence of the châteaus.
The châteaux, numbering more than three hundred, represent a nation of builders starting with the necessary castle fortifications in the 10th century to the splendour of those built half a millennium later. When the French kings began constructing their huge châteaux here, the nobility, not wanting or even daring to be far from the seat of power, followed suit. Their presence in the lush, fertile valley began attracting the very best landscape designers. Today, these privately owned châteaux serve as homes, a few open their doors to tourist visits, while others are operated as hotels or bed and breakfasts. Many have been taken over by a local government authority or the giant structures like those at Chambord are owned and operated by the national government and are major tourist sites, attracting hundreds of thousands of visitors each year. Some notable Châteaux on the Loire include Beaufort- Mareuil sur Cher – Lavoûte-Polignac – Bouthéon – Montrond – Bastie d'Urfé – Château féodal des Cornes d'Urfé – La Roche – Château féodal de Saint-Maurice-sur-Loire – Saint-Pierre-la-Noaille – Chevenon – Palais ducal de Nevers – Saint-Brisson – Gien – La Bussière – Pontchevron – La Verrerie (near Aubigny-sur-Nère) – Sully-sur-Loire – Châteauneuf-sur-Loire – Boisgibault – Meung-sur-Loire – Menars – Talcy – Château de la Ferté – Chambord – Blois – Villesavin – Cheverny – Beauregard – Troussay – Château de Chaumont – Amboise – Clos-Lucé – Langeais – Gizeux – Les Réaux – Montsoreau – Montreuil-Bellay – Saint-Loup-sur-Thouet – Saumur – Boumois – Brissac – Montgeoffroy – Plessis-Bourré – Château des Réaux
The Loire Valley wine region includes the French wine regions situated along the Loire River from the Muscadet region near the city of Nantes on the Atlantic coast to the region of Sancerre and Pouilly-Fumé just southeast of the city of Orléans in north central France. In between are the regions of Anjou, Saumur, Bourgueil, Chinon, and Vouvray. The Loire Valley itself follows the river through the Loire province to the river's origins in the Cévennes but the majority of the wine production takes place in the regions noted above.
The Loire Valley has a long history of winemaking dating back to the 1st century. In the High Middle Ages, the wines of the Loire Valley were the most esteemed wines in England and France, even more prized than those from Bordeaux. Archaeological evidence suggest that the Romans planted the first vineyards in the Loire Valley during their settlement of Gaul in the 1st century AD. By the 5th century, the flourishing viticulture of the area was noted in a publication by the poet Sidonius Apollinaris. In his work the History of the Franks, Bishop Gregory of Tours wrote of the frequent plundering by the Bretons of the area's wine stocks. By the 11th century the wines of Sancerre had a reputation across Europe for their high quality. Historically the wineries of the Loire Valley have been small, family owned operations that do a lot of estate bottling. The mid-1990s saw an increase in the number of négociant and co-operative to where now about half of Sancerre and almost 80% of Muscadet is bottled by a négociant or co-op.
The Loire river has a significant effect on the mesoclimate of the region, adding the necessary extra few degrees of temperature that allows grapes to grow when the areas to the north and south of the Loire Valley have shown to be unfavourable to viticulture. In addition to finding vineyards along the Loire, several of the river's tributaries are also well planted—including the Allier, Cher, Indre, Loir, Sèvre Nantaise and Vienne Rivers. The climate can be very cool with spring time frost being a potential hazard for the vines. During the harvest months rain can cause the grapes to be harvested under ripe but can also aid in the development of Botrytis cinerea for the region's dessert wines.
The Loire Valley has a high density of vine plantings with an average of 1,600–2,000 vines per acre (4,000–5,000 per hectare). Some Sancerre vineyards have as many as 10,000 plants per hectare. With more vines competing for the same limited resources in the soil, the density is designed to compensate for the excessive yields that some of the grape varieties, like Chenin blanc, are prone to have. In recent times, pruning and canopy management have started to limit yields more effectively.
The Loire Valley is often divided into three sections. The Upper Loire includes the Sauvignon blanc dominated areas of Sancerre and Pouilly-Fumé. The Middle Loire is dominated by more Chenin blanc and Cabernet franc wines found in the regions around Touraine, Saumur, Chinon and Vouvray. The Lower Loire that leads to the mouth of the river's entrance to the Atlantic goes through the Muscadet region which is dominated by wines of the Melon de Bourgogne grape. Spread out across the Loire Valley are 87 appellation under the AOC, VDQS and Vin de Pays systems. There are two generic designation that can be used across the whole of the Loire Valley. The Crémant de Loire which refers to any sparkling wine made according to the traditional method of Champagne. The Vin de Pays du Jardin de la France refers to any varietally labelled wine, such as Chardonnay, that is produced in the region outside of an AOC designation.
The area includes 87 appellations under the Appellation d'origine contrôlée (AOC), Vin Délimité de Qualité Superieure (VDQS) and Vin de pays systems. While the majority of production is white wine from the Chenin blanc, Sauvignon blanc and Melon de Bourgogne grapes, there are red wines made (especially around the Chinon region) from Cabernet franc. In addition to still wines, rosé, sparkling and dessert wines are also produced. With Crémant production throughout the Loire, it is the second largest sparkling wine producer in France after Champagne. Among these different wine styles, Loire wines tend to exhibit characteristic fruitiness with fresh, crisp flavours-especially in their youth.
