St Michael's Mount

St Michael's Mount is a small tidal island in Mount's Bay, Cornwall. The island is a civil parish and is linked to the town of Marazion by a man-made causeway of granite setts, passable between mid-tide and low water. The population of this parish in 2011 was 35.

The medieval castle and chapel on the island have been the home of the St Aubyn family since approximately 1650 but the earliest buildings on the summit date to the 12th century.

Historically, St Michael's Mount was a Cornish counterpart of Mont Saint-Michel in Normandy, France (with which it shares the same tidal island characteristics and the same conical shape, in spite of being much smaller), when it was given to the Benedictine religious order of Mont Saint-Michel by Edward the Confessor in the 11th century.

St Michael's Mount is one of forty-three (unbridged) tidal islands that one can walk to from mainland Britain. Part of the island was designated as a Site of Special Scientific Interest in 1995 for its geology.
