The Capel-y-Cwm Unitarian chapel was built in 1906. Coflein, the online database of the Royal Commission on the Ancient and Historical Monuments of Wales, describes it as being in the "simple round-headed style of the gable entry type".[3] The gable front is painted stucco.[4] It was the last Unitarian chapel to be built in South Wales to fill a need for the congregation who had previously been meeting in a storeroom above a shop. The chapel is in a rural setting and has a cemetery beside it. The interior of the chapel has a small gallery at the back, and there are two attached halls in which functions can take place and where the Sunday School can meet.[5]
