Overview

History & significance

Beaumaris Castle is a concentric castle built on the island of Anglesey in North Wales by Edward I following his conquest of Wales in 1295. The castle was designed by the royal engineer James of St George and represents one of the finest examples of Edwardian military architecture, featuring a symmetrical design with two circuits of defensive walls and a central keep. Although construction continued into the early fourteenth century, the castle was never fully completed, yet its impressive stone fortifications and the sophisticated defensive systems of its double walls and gatehouse remain substantially intact. The site served as an important royal stronghold to consolidate English control over the newly conquered Welsh territories and later saw military action during the English Civil War.
