English Civil War
The site was chosen for its strategic position in North East Wales. The castle was only one day's march from Chester, supplies could be brought along the River Dee and there was by a ford across to England that could be used at low tide.
Building work began in 1277 under Richard L'Engenour, who would later become Mayor of Chester in 1304. The castle and its earthworks were built by 1,800 laborers and masons using local Millstone Grit ashlar and sandstone. In November 1280, the Savoyard master mason James of Saint George began overseeing construction at Flint for Edward I. He remained at the castle for 17 months. James of Saint George then moved onto Rhuddlan to oversee its completion.
When work ceased in 1286, Flint Castle had an inner ward and an outer bailey. They were separated by a tidal moat and were connected with gatehouse and drawbridge. A plantation town was also laid out beyond the outer bailey. The inner ward had three large towers and a detached keep. This isolated tower protected the inner gatehouse and outer bailey. In total expenditure, Edward I spent £6068.7.5d. creating the fortress and the town (£4.5 million as of 2008).[nb 1]
Flint, which was sited on the western shore of the River Dee estuary, could be supplied by river or sea. Its harbour was protected by a defensive wall. The castle lies opposite to the English shore and Shotwick Castle in England. Before the river's course was drastically changed in the 18th century, passage across the estuary at this point could be made directly by boat at high tide or by fording at low tide.
Unique fortress design
The castle is based on medieval French or Savoyard models where one of the corner towers is enlarged and isolated. This independent structure served as both corner tower and keep or donjon, like at Dourdan, France. Flint's keep has been compared to the donjon at Aigues-Mortes, France. Edward I would have been familiar with Aigues-Mortes having passed through the fortress on the way to join the Eighth Crusade in 1270.
The keep is an impressive structure. Its stone walls are 7 metres (23 ft) thick at the base and 5 metres (16 ft) above. Access was gained by crossing a drawbridge into a central entrance chamber on the first floor. Originally there would have been at least one additional storey. These floors had small rooms built into the thick walls. A timber gallery was built on top of the keep for the visit of Edward, Prince of Wales in 1301. On the ground floor is a vaulted passage that runs all the way around the inside of the keep.
Flint's design was not repeated in any other castle built by Edward I in North Wales. The layout at Flint remains unique within the British Isles.
Flint was the first castle of what would later become known as Edward I's "Iron Ring". A chain of fortresses designed to encircle North Wales and oppress the Welsh. Its construction began almost immediately after Edward I began the First Welsh War in 1277.
Five years later Welsh forces under the command of Dafydd ap Gruffydd, brother of Llywelyn ap Gruffudd, besieged the castle in an attempted uprising against the English Crown. In 1294 Flint was attacked again during the revolt of Madog ap Llywelyn; this time the constable of the castle was forced to set fire to the fortress to prevent its capture by the Welsh. The castle was later repaired and partly rebuilt.
With the conclusion to the Welsh Wars, English settlers and merchants were given property titles in the new town that was laid out in front of the castle. The plantation borough was protected by a defensive ditch with a wooden palisade on earth banking. Its outline remains visible in streets patterns.
During the English Civil War, Flint Castle was held by the Royalists. It was finally captured by the Parliamentarians in 1647 after a three-month siege. To prevent its reuse in the conflict, the castle was then slighted in accordance with Cromwell's destruction order. The ruins are what remain today.
By the 19th century part of the site's outer bailey was used as Flintshire's County Jail. A quarry also operated nearby.
Flint Castle, which has been managed as public monument for 90 years, is now maintained by Cadw, a Welsh-government body that protects, conserves and promotes the building heritage of Wales. Access is free and via a path. Most parts of the castle, such as the isolated keep, are open to the public.
In mid August 2009, the agency temporarily closed Flint Castle to the public because of problems with anti-social behaviour. Cadw said youths were drinking on the site and vandalising the castle. Cadw is now liaising with North Wales Police to improve security at the castle.
