Constructed in 1268, this castle was the first in Britain to be built on a regular concentric plan. The design of its walls, towers and gateways embodied many innovative features, and it served as a model for the castles Edward I was shortly to build in North Wales. It has undergone restoration on several occasions. The visitor's approach to the castle is via the long East Barbican, a fortified dam separating the outer moat from the inner moat and its flanking lakes.

Built in 1268, this massive stronghold sits behind extensive water defences. The complex underwent restoration in the 19C and 20C and has a long barbican (a fortified dam), an outer ward with bastions, an inner ward with towers, mighty gatehouses and the Great Hall.

The museum is in a remarkably well arranged warehouse, showing various objects and containing a completely restored weaving workshop. Several decommissioned boats, including a lightboat, are moored in the docks and historical cars from the Mumbles Tram Society are on show in a hangar.
