Loughor Castle

Loughor Castle is a ruined, medieval fortification located in the town of Loughor, Wales. The castle was built around 1106 by the Anglo-Norman lord Henry de Beaumont, during the Norman invasion of Wales. The site overlooked the River Loughor and controlled a strategic road and ford running across the Gower Peninsula. The castle was designed as an oval ringwork, probably topped by wicker fence defences, and reused the remains of the former Roman fort of Leucarum.
