St Michael's Mount (, (Carrek Los yn Cos), meaning "hoar rock in woodland", also known colloquially by locals as simply
the Mount is a small
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. The population of this parish in 2011 was 35. It is managed by the
National Trust, and the castle and chapel have been the home of the
St Aubyn family since approximately 1650. The earliest buildings, on the summit, date to the 12th century, the harbour is 15th century and the village and summit buildings were rebuilt from 1860 to 1900, to give the island its current form.
