St Aldhelm's Chapel is a Norman chapel on St Aldhelm's Head near Worth Matravers, Dorset. It is a Grade I listed building.
The square stone chapel stands within a low circular earthwork, which may be the remains of a pre-Conquest Christian enclosure. The building has several architectural features which are unusual for a chapel; the square shape, the orientation of the corners of the building towards the cardinal points, and the division and restriction of the interior space by a large central column. The lack of evidence for an altar or a piscina suggests that the building may not have been built as a chapel. It may have originally been built as a watchtower for Corfe Castle, covering the sea approaches to the south.
The interior of the chapel is approximately 25 feet square. In the centre is a square pier supporting four square rib vaults, with the heavy ribs leading to transverse arches, all stop-chamfered. In the north-west side is a Norman round-arched doorway. A small window is contemporary with the doorway.
During the late 19th and early 20th centuries regular weekly services were held, attended by coastguards and their families who lived in nearby cottages.
