SEALED All surface features remain intact but the concrete apron around the access shaft is beginning to break up and the step is broken. The FSM pipe is bent over. There is some flaking of the light green paint. Although no fencing remains, there is an old gate in the hedgerow. The hatch is sealed with 6 inches of concrete. A metal dome on the ventilation shaft indicates this was a master post and three aerial guying points are visible.
Opened in 1965 and closed in 1991.
