Beaumaris Castle was the last of Edward I\’s fortresses in North Wales. Work started in 1295 and continued for 35 years, with over 3,500 workmen employed at the peak of construction. Beaumaris castle was positioned to face Garth Celyn on the opposite shore of the Menai Strait and was intended, along with Conwy Castle and Caernarfon Castle at either end of the Menai Strait, to overshadow the Welsh Royal home and centre of resistance to the English forces.
