In a field 120 yards South of Gilberts Monument on The Beacon.
DEMOLISHED The post was demolished in 1992 although it is suspected that the surface features were pushed into the shaft and the monitoring room still exists below ground. The only evidence today is the entrance gateway through a wall (gate missing). The site of the post is now a picnic area with tables and seats.
The concrete foundations of the aircraft post can still be seen near the hedge west of the gateway at SX95943252
Opened in 1961 and closed in 1991.
