What is recorded here

Alderstead Fort is a Second World War anti-tank defensive position at Merstham in Surrey. Built during the 1940 German invasion threat, its concrete obstacle and earthworks represent emergency wartime defence and civilian mobilisation across southern England. The preserved remains still show the urgency of that moment and the practical engineering used to protect the Home Counties.

Alderstead Fort is shown as a fort on the public map of Reigate and Banstead. The saved point is the map point or the centre of its mapped shape.

Alderstead Fort is a medieval earthwork fortification, likely built in the 13th or 14th century, and may have been held by local landowners for defensive or strategic purposes. It is remembered as an example of the regional earthwork castles that were constructed to provide local protection during periods of political instability.
