Penrice is the largest castle on the Gower and is in a pretty decent state of repair. It has an interesting history in that after the Norman invasion of south Wales one of the successful invading knights was granted land near what is now Penrice village. He took the family name de Penrice and built Penrice castle. The Penrice family still own the estate some 29 generations later. Therefore the castle is on private land but a nearby public footpath allows viewing of certain portions of the wall and towers.
