OPEN Most surface features remain intact although the ventilation louvres are missing and the top of the ventilation shaft is missing as is the BPI pipe. The FSM pipe is surrounded by a concrete column. The hatch is open. Internally there is a little water at the bottom of the shaft, otherwise the monitoring room is clean and dry and free of any vandalism. Remaining artefacts include the table, shelf (detached), cupboard, twin bunks, BPI mount, GPO dry cell, post battery in its box, wiring, siren box and the hatch locking bar.
Opened in 1960 and closed in 1968.
