St Michael’s Mount is a tidal island in Mount’s Bay near Penzance, England, about a 15 minute drive from the B&B in which we stayed. The island is a civil parish (a local government) and is linked to the town of Marazion by a causeway of granite stones, passable between mid-tide and low water (which you can tell wasn’t possible when we were there). The earliest buildings on the summit, including a castle and monastery buildings, date to the 12th century. St Michael's Mount is 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.
