The name Kenfig once referred to a busy medieval borough town situated on the coast of South Wales. The town was engulfed by sand storms in the Middles Ages until it was completely obliterated, apart from the remains of its castle, which is still visible. Its inhabitants moved to higher ground, where a church was built at Mawdlam, and nearby, the old town hall still stands in the form of the Prince of Wales public house, where the Trustees of Kenfig Corporation, the present equivalent of the burgesses, still meet.
Much of Kenfig is now a National Nature Reserve and its freshwater Pool is a haven for migrating wildfowl. The surrounding dunes contain many varieties of plantlike, including rare orchids.
Although the population is now much smaller, the people of Kenfig still lead their lives within a short distance of the medieval town, overlooking the sand dunes that buried it so many years ago.
