Castles to visit Mumbles

The medieval castle offers a splendid view of the bay. It was built in the 12th century by Henri de Beaumont, Duke of Gower. As his main residence was built on the current Swansea site, Oystermouth Castle was in fact primarily intended to expand the northwestern surveillance field. The strange appearance of the main façade comes from the absence of the two towers that should have flanked its entrance; they were never built. Even when closed, the castle and park are still worth a look.
