Cramond Island

Cramond Island is located in the River Forth, near Edinburgh. During WW1 and WW2 the island was fortified for defensive purposes. The island is connected to the shore by a causeway upon which sits a line of concrete pylons, 3m high. These were installed during WW2 to prevent torpedo boats passing between the island and mainland at high tide to attack naval assets upstream. The island is now uninhabited and can be accessed at low tide with a fifteen minute walk along the causeway.
