Beaumaris Castle on the Island of Anglesey is a great unfinished masterpiece. It
was begun in 1295 as one of the 'iron ring' of North Wales castles by the English monarch
Edward I, to stamp his authority on the Welsh but it was never finished, money and
supplies ran out before the fortifications reached their full height.
The fortification is built of local stone, with a moated outer ward guarded by 12
towers and two gatehouses, overlooked by an inner ward with two large, D-shaped
gatehouses and six massive towers.
