Alderstead Fort is a Second World War anti-tank defensive position located at Merstham in Surrey. Constructed as part of the extensive stop line fortifications built across southern England following the threat of German invasion in 1940, the fort comprises a concrete anti-tank obstacle and associated earthworks typical of emergency wartime defences. The site represents the civilian mobilisation effort and military preparedness of the early war period, when the Home Defence organisation sought to create a layered defensive network across the Home Counties. The physical remains retain archaeological significance as evidence of wartime engineering and the strategic concerns of 1940.
