On a forty foot high limestone ridge overlooking the pretty village of Mumbles Oystermouth Castle is a spectacular location.  The earliest building remains at Oystermouth Castle, the keep in the central block, date from the early 12th century.Used as the residence of the Marcher Lords of Gower it was frequently under attack from the local Welsh. In the twelfth century the castle was mainly owned by the first Earl of Warwick and his family. In 1203 the lordship of Gower was given to the de Breos family who ruled until the 1320s when it passed into the hands of the de Mowbray’s via Alina de Breos who married John de Mowbray. The de Mowbrays lost Gower to the Beauchamps for some time due to a legal decision and in 1461 it passed to the Herberts, the Somersets and then to the Dukes of Beaufort who held it until 1927 when it was transferred to Swansea Corporation. Currently it is the responsibility of the Swansea City Council and supervised by the Friends of Oystermouth Castle.

Attractive, but surprisingly well hidden (even being halfway up a hill).Originally built as an English stronghold in Wales in the C12th, and feels like a real fortress. It did, however, fall into Welsh hands and influence. A fine keep, and closely surrounding curtain walls, give the impression of a small bastion in a turbulent South Wales, but with all things...

Something to do if visiting Mumbles but parking nearby is limited especially at weekend. Charging to visit ruins is debateable as there is nothing to see apart from the views.

Nice castle but in disrepair with pigeon muck and feathers everywhere. A shame as if restored could be really good. We spent about an hour then you had seen it all

A number of bus routes from the city centre stop within easy walking distance of the castle with the #2 stopping directly opposite. The castle is now just a shell but has some great hidden stairways and... More

This castle on a hill overlooking the Swansea bay and particularly Mumbles is often host to concerts and local events. Even when quiet it host a spectacular view and particularly so on a clear day.
