OysterMouth Castle

This is the Gower Peninsula's finest castle, standing on a small hill with a magnificent view over Swansea Bay in the resort town of Mumbles. It is well-preserved, intricate and exciting to explore. Oystermouth Castle was founded by William de Londres of Ogmore Castle early in the 12th century. .

Over recent years the castle has undergone conservation work.

Now the public can explore parts of the castle that have been hidden away for centuries and learn about the castle’s exciting history.

New features include ancient graffiti art from the 14th century, private staircases leading from vaults to previous banqueting halls and a 30 foot high glass bridge. Events are held throughout the year, so come along and make a visit to one of Wales’ finest castles.
