Culbone is a hamlet in the civil parish of Oare in West Somerset district, in the Exmoor National Park. It consists of a few houses and the church, close to the SW Coast Path, set in woodland less than ¼ mile from the sea at Porlock Bay. The large village of Porlock is 3 miles ESE. The church consists of a 2-bay nave with a W bell-cote with a slate-hung spirelet, and a S porch, and a chancel. Herringbone masonry in the W wall suggests a pre-Norman date for some fabric. The nave was given new windows in the 15th-16thc and the porch dates from the 13thc, and there are additions and signs of restoration on the 19thc. Construction is of local stone – random rubble partly whitewashed. Romanesque features described here are the chancel N window and the font.
The dedication was originally a ‘Celtic’ one. Like other churches along the English shore of the Bristol Channel (e.g., Congresbury, Watchet, Porlock, Braunton, Hartland), Culbone was connected with strong early monasteries and missionary and activity located in Glamorgan (notably at Llantwit connected with St Illtud and at Llancarfan).
