Beaumaris was set to be Edward I’s final castle in North Wales and despite plans being made to construct the fortress as early as 1282, a lack of funds and a local rebellion meant that work didn’t begin in 1295. Ongoing issues in Scotland meant that funds were constantly diverted from the project and by 1300, worked had stopped all together. 

By 1306, Edward became concerned about possible Scottish invasion of North Wales and work recommenced. Despite huge sums being spent on the castle, work finally halted for good in 1330 and the castle was destined to never be completed.
