Photography: Maunsell Sea Forts

The Maunsell Forts were small fortified towers built in the Thames and Mersey estuaries during the Second World War to help defend the United Kingdom. They were designed by Guy Maunsell in 1942 to house anti-aircraft guns and search lights. The forts were decommissioned in the late 1950s and later used for other activities. Nowadays a consortium called Project Redsands is planning to conserve these magnificent remnants.
