Oystermouth (a corruption of the Welsh name Ystum Llwynarth or Ystumllwynarth) is a village (and former electoral ward) in the district of Mumbles, Swansea, Wales. It is part of the Mumbles community (civil parish). Description The ward consists of suburban housing stretching from the northwest to the southeast. It is surrounded by the sea to the east and south. Two hills at Rams Tor and Mumbles Hill have little development. Mumbles Hill is now a protected nature reserve managed by the local council. The boundaries of Mumbles community and the Oystermouth ward are clearly defined. However, in the public mind, the separation between villages of Oystermouth and Mumbles is not clear. Local buses to the area are signed as Oystermouth, although most people from the area would say they are living in Mumbles. Local beaches include the southern tip of Swansea Bay, Bracelet Bay and Limeslade Bay. From the Mumbles Head area, there are views towards Swansea, Port Talbot, and the hills of the South Wales Coalfield. Oystermouth is the site of Oystermouth Cemetery. Oystermouth was served by the Swansea and Mumbles Railway, one of the very earliest passenger rail services, along a shoreline railway used in the 19th century to transport limestone and coal.
