On a mound 20 yards east of Edmire Lane on the edge of a disused airfield. Opposite the drive to Topcliffe Manor Farm.
OPEN The mound has been cut back all round and this has caused the concrete apron around the access shaft to crack in several places. All surface features remain intact and in good condition with some green paint and the ventilation louvres remaining. The step and the hatch are detached. Internally the walls of the monitoring room are covered in graffiti. Remaining artifacts include twin bunks, single bed, table, shelf, cupboard, BPI mount, GPO junction boxes and wiring.
Opened in 1964 and closed in 1968.
