Hay Castle initially took the form of an earth ringwork with a stone gate-tower.; It was re-enforced in stone around 1200 with a curtain wall. The castle was damaged during the Welsh rebellion led by Owain Glyndŵr around 1401 and again in 1460 during the Wars of the Roses. It was then substantially expanded in the 17th century, creating a Jacobean mansion. Hay Castle has recently been restored to its former glory.
