Church

St Cwyfan's church was in existence by 1254 and was enlarged in the 14th and 15th centuries. The building later fell into disrepair, and in the 19th century parts of the church were demolished. By 1891 the surviving part was roofless, so an appeal was launched which paid for the building of a new roof. In about the 1970s all the windows were restored, but now the building is deteriorating again and a new restoration appeal has been launched.

Therefore, it seems to be after that date that sea erosion of the
