A tidal island is a raised area of land within a
waterbody , which is connected to the larger mainland by a natural
isthmus or man-made
causeway that is exposed at low
tide and submerged at high tide, causing the land to switch between being a
promontory /
peninsula and an
island depending on tidal conditions.
Because of the mystique surrounding tidal islands, many of them have been sites of
religious worship , such as
Mont-Saint-Michel with its
Benedictine
Abbey . Tidal islands are also commonly the sites of
fortresses because of the natural barrier created by the tidal
channel .
