Aberystwyth Castle is located in Aberystwyth, Ceredigion, Mid Wales.
The construction of Aberystwyth Castle began in 1277. The area had hosted other castles before it, the earliest being a fortress dating back to the Iron Age.
Aberystwyth Castle was built as a diamond-shaped concentric fortress, with gatehouses at each point. Its walls-within-walls defences allowed its guards to fire down from different heights, helping to avoid friendly fire. Beyond its guardtowers, the castle had two gatehouses, a barbican and a tall tower in the castle's inner ward. Today the castle rubble only hints at its past, its imposing structure destroyed by warring and its proximity to Cardigan Bay.
