Oystermouth Castle

Oystermouth Castle is a stone fortress perched on a hilltop overlooking Swansea Bay, featuring remains of medieval defensive structures. The site contains partially intact towers, walls, and courtyards that reveal how such fortifications were organized and built.

The fortress was established in the early 12th century and endured repeated cycles of destruction and reconstruction during conflicts between Norman and Welsh forces. These struggles shaped the fragmented state of the ruins today.

The castle represents a frontier between two worlds, where Norman settlers and Welsh inhabitants existed in constant tension. Its layout and defensive design show how power was maintained over a contested landscape.

The site is accessible year-round, but visiting during dry weather is advisable as the hilltop location makes paths slippery when wet. Comfortable footwear is essential, and plan enough time to explore all areas at a leisurely pace.

During restoration work, modern viewing platforms were added to provide vistas across the bay without compromising the historic ruins. This blend of preservation and access reflects how heritage sites adapt to contemporary use.
