St Michael's Mount is a tidal island in Mount's Bay, Cornwall, England, United Kingdom. The island is a civil parish and is linked to the town of Marazion by a 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 around 1650.
Historically, St Michael's Mount was an English counterpart of Mont-Saint-Michel in Normandy, France, which is also a tidal island, and has a similar conical shape, though Mont-Saint-Michel is much taller.
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.
