Bethesda Baptist Chapel was built in 1789 and enlarged in 1816. The chapel was destroyed by gas explosion and subsequently rebuilt in 1842. The present chapel was built in 1878, to the design of architect George Morgan of Carmarthen, in the Italian Romanesque style of the gable-entry type. The chapel is constructed of local and bath stone, with a Caernarfon slate roof and large rose window. Bethesda is now Grade 2* Listed as a major work of George Morgan.
