The church dedicated to Brynach, an Irish saint from the sixth century, was erected in the twelfth century. It ceased to be used at the end of the 17th century, when it was isolated from any nearby settlement. In the 19th century, it was renovated.
The building consists of a wide, rectangular nave, a much narrower and lower chancel on the eastern side and a tower on the western side. The porch adjoins the southern wall of the nave. Inside, there are traces of medieval wall polychromes, a timber roof truss and rare stone benches dated to the twelfth century on the north and south sides of the nave. The square opening on the nave side by the chancel arch, gave the opportunity to view the altar from behind the rood screen. In the south wall of the presbytery there is a piscine with a small square hollow, which was probably a storage for holy vessels and liturgical vestments. The chancel floor is lined with tombstones from the 13th century.
