HER 1061 - Alderstead Fort: a London mobilisation centre at Merstham
Scheduled Monument
Alderstead Mobilization Centre or Fort at East Merstham erected in 1890s as part of a London Defence Scheme. The monument falls into two separate areas and includes the main compound and tool store of East Merstham mobilisation centre, known as Alderstead Fort, situated on a chalk ridge of the Surrey Downs. The main compound forms the south-western part of the monument and houses a three-roomed magazine fronted by five casemates. It survives as a roughly north west-south east aligned, north east facing, flat-roofed structure constructed mainly of reinforced concrete and brick, with a large, crescent-shaped earthen blast-bank partly covering and flanking the magazine to the rear. Beyond the bank is an up to 10m wide ditch. The building retains many original fittings, including iron-and-wood door and window shields and
magazine vents.
The associated red-brick tool store lies around 75m to the north east and is a north east-south west aligned, single storey, rectangular building measuring 14m by 10m, with white washed sandstone dressings under a pitched, blue slate roof. The south-eastern face has full-length, central double doors flanked by tall windows with iron grilles.
