Description
Y castell hwn, y dechreuwyd ei adeiladu yn 1295, oedd yr olaf mewn rhwydwaith strategol o gadarnleoedd mawr a adeiladwyd ar draws Cymru gan y Brenin Edward I (1272–1307), ar ôl Caernarfon, Conwy a Harlech yn 1283. Adeiladwyd Castell Biwmares ar ôl gwrthryfel mawr gan y Cymry yn 1294–95, pan brofwyd amddiffynfeydd tri chastell Edward i’r eithaf.Begun in 1295, Beaumaris Castle was the last in a strategic network of great fortresses built across Wales by King Edward I (1272–1307) after Caernarfon, Conwy and Harlech in 1283. It was built following a widespread Welsh revolt in 1294–95, during which time the defences of Edward’s trio of castles were put to the test.
