Beaumaris on the Isle of Anglesey in north-western Wales is part of the iron-ring built by Edward I in the late 13th c., built to garrison the rebellious Welsh. Beaumaris Castle was the last of Edward I's fortresses in North Wales and was built to complement Conwy, Caernarfon and Harlech castles in the same area (iron-ring). Many people regard Beaumaris as the most architecturally perfect castle in Britain, and it has been designated as a World Heritage site. However, the fortress was never fully completed as finances and material ran out before it reached its full height.
