Tidal island
A tidal island is a piece of land that is connected to the mainland by a natural or man-made causeway that is exposed at low tide and submerged at high tide. 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 their natural fortifications.
The former Bennelong Island in Sydney , Australia was developed into Bennelong Point and is now the location of the Sydney Opera House .
