The chancel of this church, which stands in woods, overlooking Oxwich Bay, marks the original sixth century Celtic cell.

Entry to the church is through the west door, in the tower, where there are two tombstones mounted against the walls with the following plaques:

"GRAVE COVER STONE" found used as a slab, face upwards, inside the inner door of the church, one side having been cut away level for this purpose. The fragment of the inscription which remains proves that it commemorates William De La Lake, who was rector of Oxwich, from 1320 to 1323 AD.

The stone was placed here in 1890.
