What is "porthcawl"

Porthcawl is a town and community on the south coast of Wales in the county borough of Bridgend, west of the capital city, Cardiff and southeast of Swansea. Situated on a low limestone headland on the South Wales coast, overlooking the Bristol Channel, Porthcawl developed as a coal port during the 19th century, but its trade was soon taken over by more rapidly developing ports such as Barry. Northwest of the town, in the dunes known as Kenfig Burrows, are hidden the last remnants of the town and Kenfig Castle, which were overwhelmed by sand about 1400.
