Description
The see-saw searchlight emplacement at Fort Victoria is an experimental structure built in 1888 by the Royal Engineers as part of the submarine mining depot. Although the searchlight apparatus has been removed, the concrete emplacement remains largely intact.
The emplacement features a concrete superstructure with a base integrated into the foreshore embankment that overlooks the sea. Steel beams support the underside of the roof. The structure is mostly semi-circular in shape, with a centrally located truncated concrete cone that once held the traversing searchlight apparatus. Surrounding this cone is a lower concrete platform that allowed for easy maneuvering of the searchlight. This platform is partially covered by a reinforced concrete roof for protection. The emplacement measures approximately 10 meters in width, 5 meters in depth, and is partially sunken into the ground by about 2.5 meters.
