Loughor Castle is a ruined, medieval fortification located in the town of Loughor, Wales. It was built around 1106 by the Anglo-Norman lord Henry de Beaumont, during the Norman invasion of Wales. Although it looks like a motte and bailey it actually started out as a ringwork which was then filled in and the stone keep was built on top with building material nicked from the nearby Roman fort of Leucarum. The original structure was made of wicker.
