Flint Castle, the earliest and most unusual English-built castle in Wales, is a must-visit for military architecture enthusiasts. Founded in 1277 as part of Edward I’s campaign against Llywelyn ap Gruffydd (Llywelyn the Last) in north Wales, Flint Castle boasts a unique and unusually sophisticated design.
Started in 1277 and largely completed by 1284, the castle is dominated by its grand south-east corner tower, known as the donjon. Surrounded by its own moat and accessible via a drawbridge, it essentially functions as a castle within a castle. Built with exceptionally thick walls and equipped with all the necessary facilities to withstand a siege, Flint Castle was likely intended as a final refuge in case of an attack.
Flint Castle’s fame extends beyond its architectural significance. It is also known as the site of a fateful meeting in 1399 between Richard II and his rival to the crown, Henry Bolingbroke (later known as Henry IV). This pivotal encounter was immortalised in Shakespeare’s play “Richard II.”
