Groningen (//, also UK: /-/, US: /-/, Dutch: [ˈɣroːnɪŋə(n)] (listen); Gronings: Grunn or Grunnen) is the capital city and main municipality of Groningen province in the Netherlands. It is the largest city in the north of the Netherlands. As of December 2020, it had 233,218 inhabitants. It has a land area of 168.93 km2 (65.22 sq mi), and a total area, including water, of 180.21 km2 (69.58 sq mi). Its population density is 1,367 residents per km2 (3,540 per square mile). On 1 January 2019, it was merged with the municipalities of Ten Boer and Haren. The Groningen-Assen metropolitan area has about half a million inhabitants. Groningen is a university city, and students comprise an estimated 25% of its total population. Groningen was established more than 950 years ago. Historically, it was a semi-independent city-state, a member of the German Hanseatic League, and the dominant regional power in the north of the Netherlands.
The origin and meaning of 'Groningen' and its older variant, 'Groeningen', are uncertain. A folk origin story relates the idea that, in 453 BC, exiles from Troy who were guided by a mythical figure called Gruno (or Grunius, Gryns or Grunus), along with a group of Phrygians from Germany, founded a settlement in what is now Groningen, and built a castle on the bank of the Hunze, which they called 'Grunoburg', and which was later destroyed by the Vikings.
One modern theory is that 'Groningen' meant 'among the people of Groni' ('Groningi' and 'Groninga' in the 11th century), derived from Gronesbeke, which was the old name for a small lake near the Hunze (on the northern border of Zuidlaarderveen). Another theory is that the name was derived from the word groenighe, meaning 'green fields'.
During the French occupation of the area, Groningen was called Groningue. In Frisian, it is called Grins. In Gronigen province, it is called Groot Loug. Regionally, it is often simply referred to as the Stad (the “city”), and its inhabitants are referred to as Stadjers or Stadjeder. Netherlanders often refer to it as “the Metropolis of the North", or Martinistad (after Martinitoren tower.
The city was founded at the northernmost point of the Hondsrug area. While the oldest document referring to Groningen's existence dates from 1040, the city was occupied by Anglo-Saxons centuries prior. The oldest archaeological evidence of a civilization in the region stem from around 3950–3650 BC, and the first major settlement in Groningen trace back to the year 3 AD.
In the 13th century Groningen was an important trade centre and its inhabitants built a city wall to underline its authority. The city had a strong influence on its surrounding lands and the Gronings dialect became a common tongue. The most influential period of the city was at the end of the 15th century, when the nearby province of Friesland was administered from Groningen. During these years the Martinitoren was built which is considered to be the city's most significant landmark.
In 1536, Groningen accepted Emperor Charles V, the King of Spain and the Habsburg ruler of the other Netherlands as its ruler, thus ending the region's autonomy. The city was captured in the Siege of Groningen (1594) by the Dutch and English forces led by Maurice of Nassau. After the siege, the city and the province joined the Dutch Republic.
The University of Groningen was founded in 1614 with initial course offerings in law, medicine, theology and philosophy. During the same period the city expanded rapidly and a new city wall was built. The Siege of Groningen (1672) led by the bishop of Münster, Bernhard von Galen during the Third Anglo-Dutch War failed and the city walls resisted; an event that is celebrated annually with music and fireworks on 28 August as "Gronings Ontzet" or "Bommen Berend".
During World War II, the main square and the Grote Markt were largely destroyed in the Battle of Groningen in April 1945. However, the church Martinitoren, the Goudkantoor, and the city hall escaped damaged.
Groningen has an oceanic temperate climate, like all of the Netherlands, although slightly colder in winter than other major cities in the Netherlands due to its northeasterly position. Weather is influenced by the North Sea to the north-west and its prevailing north-western winds and gales.
Summers are somewhat warm and humid. Temperatures of 30 °C (86 °F) or higher occur sporadically; the average daytime high is around 22 °C (72 °F). Very rainy periods are common, especially in spring and summer. Average annual precipitation is about 800 mm (31 in). Annual sunshine hours vary, but are usually below 1600 hours, giving much cloud cover similar to most of the Netherlands. Climate in this area has mild differences between highs and lows, and there is adequate rainfall year-round. The Köppen Climate Classification subtype for this climate is "Cfb". (Marine West Coast Climate/Oceanic climate).
Winters are cool; on average above freezing, although frosts are common during spells of easterly winds. Night-time temperatures of −10 °C (14 °F) or lower are not uncommon during cold winter periods. The lowest temperature ever recorded is −26.8 °C (−16.2 °F) on 16 February 1956. Snow often falls, but rarely stays long due to warmer daytime temperatures, although white snowy days happen every winter.

Hotel and catering industries constitute a significant part of the economy in Groningen. Focus on business services has increased over time and areas such as IT, life sciences, tourism, energy, and environment have developed.
Until 2008 there were two major sugar refineries within the city. The Suiker Unie plant was constructed in the outskirts of Groningen, but became a part of the city due to expansion. The factory had 98 employees before it was shutdown in 2008 due to a reduction in demand. As of 2017, CSM Vierverlaten in Hoogkerk remains the only beet sugar production plant in the city. Other notable companies from Groningen include publishing company Noordhoff Uitgevers, tobacco company Royal Theodorus Niemeyer, health insurance company Menzis, distillery Hooghoudt, and natural gas companies GasUnie and GasTerra.

Cycling and walking
Groningen is known as the "World Cycling City"; around 57% of its residents use a bicycle for regular commute within the city. In 2000, Groningen was chosen as the Fietsstad 2002, the top cycle-city in the Netherlands for 2002. Similar to most Dutch cities, Groningen is developed to accommodate a large number of cyclists. An extensive network of bike paths were planned to make it more convenient to cycle to various destinations instead of taking a car.
The city has segregated cycle-paths, public transport, and a large pedestrianised zone in the city centre. Groningen's city centre was remodeled into a "pedestrian priority zone" to promote walking and biking. This was achieved by applying the principle of filtered permeability—the network configuration favours active transportation and selectively "filters out" traveling in a car by reducing the number of streets that run through the centre. The streets that are discontinuous for cars connect to a network of pedestrian and bike paths which permeate the entire centre. In addition, these paths go through public squares and open spaces, increasing the aesthetic appeal of the trip and encouraging more participation. The logic of filtering a mode of transport is fully expressed in a comprehensive model for laying out neighbourhoods and districts—the fused grid.
Groningen railway station (in Dutch: Hoofdstation) is the main railway station and has regular services to most of the major cities in the country. The city's remaining two railway stations are Europapark and Noord.
