Flint Castle

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.

Building work began in 1277 initially under Richard L'engenour, who would later become Mayor of Chester in 1304. The castle and its earthworks were built by 18,000 labourers and masons using local Millstone Grit ashlar and sandstone. Savoyard master mason James of Saint George was assigned "ad ordiandum opera castorum ibidem" (to undertake the works of the same castle works (referring to all Welsh castle building projects) in April 1278. November 1280 saw him beginning directly overseeing construction at Flint for Edward I as the initially very slow construction pace was accelerated.

In 1838 J. M. W. Turner painted a watercolour of the castle. HMS Flint Castle (K383) was a Royal Navy Castle-class corvette launched in 1943, named after Flint Castle.
