The castle is situated in a prominent position overlooking Oystermouth, Mumbles and Swansea Bay. Originally built around 1100 AD, it has suffered various destructive events from invasions. Most of what is visible today was rebuilt after an attack in 1287. It was home for a number of the lords of Gower during the thirteenth and fourteenth centuries. The chapel block has some fine tracery windows which have been regarded by some as amongst the best in Wales. During the summer, open air plays are performed below the castle walls.
