The church in Rhossili was erected at the end of the twelfth or early thirteenth century and replaced the 50 years older building, which was covered with sand of the coastal dunes, during a great storm. The new temple was built on high cliffs, not to repeat the fate of the elder. It was donated by William de Turberville to the Order of the Knights Hospitaller, and after the cassation of the order in England by Henry VIII, the patron of the temple went to the Crown. The church was heavily rebuilt in the 19th century during a Victorian renovation.
The church consists of a rectangular nave and a narrower and shorter, rectangular chancel on the eastern side. On the west side there is a four-sided tower. It is certainly a later addition, as it blocking the western window. From the south side, the entrance to the nave is closed by the porch, inside of which there is a magnificent romanesque portal, possibly from the older temple. The original windows crowned with trefoils are located in the north and south walls of the presbytery.
