Oystermouth Castle set in the Gower Peninsula was first built in 1106 by William de Londres of Ogmore Castle. In 1116 the Welsh rove him out and burnt the castle down. It was destroyed again by the Welsh in 1137 after being rebuilt. The Gower Lordship was given to John de Braose who also owned Swansea Castle after the area had become more stabilized by 1220.
