The first Shoebury Boom was constructed in 1939 to stop enemy submarines from making their way up the Thames. The orignal boom was made out of wood and was demolished in 1945. A second boom was then built between 1950 - 53 a a Cold War defence boom and this time was contructed of concreete piles some 15 - 60 yards apart connected by a metal bar across the top. A similar structure exists on the Isle of Sheppey. Metal gates connected the boom either side of the Thames and this could then open or close the Thames to shipping. The Shoebury Boom is the only Cold War structure of its type and is a listed structure.
You can also see a wind farm and in the distance you may be able to spy the Maunsell Forts. Also visible to the left of the Shoebury Boom is folly bank, an artifical sandbank which was created when they were going to build a new airport for London over these mudflats.
