Description

This is a light anti-aircraft gun emplacement built for the former Thorp Arch Royal Ordnance Factory. It is constructed from brick and reinforced concrete, featuring a steel gun mounting. The emplacement is low and circular, nearly 5 meters in diameter, with a flat concrete roof that has a central hole almost 1.5 meters in diameter for the gun mounting to project through. The steel gun mounting is secured onto a concrete pedestal that rises from the floor of the emplacement, allowing the gunner to stand on it, with spare ammunition stored beneath the concrete roof. Access to the ammunition store is provided by a low open doorway on the west side, which is protected by an outer brick blast wall. Additionally, there is a second access point: a very low hatchway, which retains its timber door, located at the base of the emplacement's wall on the southeast side.
