Not far from Porthcawl, Bridgend in Glamorgan in South Wales lies Kenfig Pool that according to legend has a drowned town beneath its waters. Kenfig Pool is now part of a Kenfig National Nature Reserve which is designated a Site of Special Scientific Interest and also a part of an important active sand dune system along the Glamorgan coast. The original borough of Kenfig was a place of some significance centred around or near Kenfig Castle. Both castle and town became buried by shifting sands during the late medieval period and the residents resettled further inland.
The drowning of Kenfig
According to local tradition the Kenfig Pool is said to be fed by seven springs and is bottomless. It is actually known to be about 12 feet deep. There is also supposed to be a whirlpool that drags boaters and swimmers to their doom called Black Gutter. Another legend tells that where the lake now stands there was once a thriving town that sank and became covered by water.
