Edward 1st (longshanks) infamous Welsh Castle at Flint

The 1st famous castle king edward I created in wales to strength the english control across the river dee boarder. Flint Castle (Welsh: Castell y Fflint) in Flint, Flintshire, was the first of a series of castles built during King Edward I's campaign to conquer Wales. 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. 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 a ford nearby across to England that could be used at low tide. Flint Castle is also famous as the location of a fateful meeting in 1399 between Richard II and his rival to the crown Henry Bolingbroke (later Henry IV), an event immortalised in Shakespeare’s Richard II.
