Cwmtwrch

The legend relates to one of Arthur's tasks: to rid the western Brecon Beacons of the pack of wild boars that were terrorising the people.

On the Black Mountain, he picked up a large stone (the carreg fryn fras) and cast it towards the wild animals, striking dead the leader of the pack on the edge of a valley near Craig-y-Fran Gorge.

The manor passed to the Morgan family of Tredegar House, Newport South Wales, by the late 18th century.

The now vanished Tir-y-gof Farm was used by drovers as a base where their cattle were shod on their long journeys to market.

Ebeneser Rees (1848–1908), the founder of the "Llais Llafur" newspaper, was raised in Cwmtwrch and is buried in the Beulah Chapel Cemetery, Palleg.

The village football team, Cwm Wanderers A.F.C., is long established and successful, having won the Neath Premier Division on 16 occasions.
