Swansea Castle is a medieval fortress founded in the early twelfth century, likely around 1106, by Henry de Beaumont following the Norman conquest of Glamorgan. The castle occupies a commanding position on a steep rock outcrop overlooking the River Tawe and the settlement of Swansea, serving as both a defensive stronghold and administrative centre for the Norman lordship. Its surviving structures include a substantial stone keep and curtain wall fragments, evidence of significant investment in stone fortification during the twelfth and thirteenth centuries. The castle remained an important military and administrative installation throughout the medieval period, though it declined in strategic importance following the Tudor conquest of Wales in the early sixteenth century.
