A small Norman chapel just inland from the harbour, dating from the 11th century when Herm was used by the Augustinians as a remote monastic retreat. Whitewashed, single-naved, with a thick granite-walled simplicity that has been left intact through multiple restorations.
The chapel is non-denominational and not consecrated. A weekly summer service is held in English; visitors are welcome to step inside any time. The walled garden outside is one of the most peaceful spots on the island.
