St Michael's Mount is a tidal island in Mount's Bay, Cornwall, United Kingdom. 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. It is managed by the National Trust, and the castle and chapel have been the home of the St Aubyn family since approximately 1650.
Historically, St Michael's Mount was a Cornish counterpart of Mont-Saint-Michel in Normandy, France, when it was given to the Benedictine religious order of Mont Saint-Michel by Edward the Confessor in the 11th century.
The castle and garden are generally open Mon - Fri from 10:30 am to 5 pm. The castle is also usually open on Sun, but the garden is closed during the whole weekend.
