The dedication of the church to Deiniol is attested in the fifteenth century. The church appears to be that mentioned as a cell occupied by Deiniol according to Dafydd Trefor: Meudwy ydoedd meudwydy⁠⁠ | Pen fu ar fraich Penfro fry (He was a hermit in a hermit’s cell | when on Pembroke’s headland on high).

The church fell into ruins in the eighteenth century but was restored and was used extensively by the Methodists and then Baptists. It is now disused but the tower still stands.
