Aberystwyth Castle

Aberystwyth Castle (Welsh: Castell Aberystwyth) is a Grade I listed Edwardian fortress located in Aberystwyth, Ceredigion, Mid Wales. It was built in response to the First Welsh War in the late 13th century, replacing an earlier fortess. During a national uprising by Owain Glyndŵr, the Welsh captured the castle in 1404, but it was recaptured by the English four years later. In 1637 it became a Royal mint by Charles I, and produced silver shillings. The castle was slighted by Oliver Cromwell in 1649.
