Loughor Castle, a ruined medieval fortification in the town of Loughor, Wales, occupies a site with over two millennia of military significance. Originally established by Romans around AD 75 as the fort Leucarum to control a fording point across the River Loughor, the castle was later built around 1106 by Anglo-Norman lord Henry de Beaumont during the Norman expansion into south Wales. The strategic location, naturally protected by boggy ground and overlooking the estuary, made it instrumental in securing the Gower Peninsula. The ruins command views across what was once a vital river crossing, and the site benefits from its position where landscape and water defenses created a formidable stronghold. Managed by Cadw, it offers free public access year-round.
