Location On Wroughton Airfield on the West side of a track from emergency exit to Priors Hill. 150 yards North of Hanger D3. The airfield is now owned by the Science Museum and is a secure site.
Description LOCKED The post replaced the nearby Toot Hill post which closed in 1967 because of water ingress that couldn't be cured, it was therefore one of the last underground posts to be built. All surface features remain intact. Science Museum staff cut the locks off (having lost the keys) for this inspection but it is their intention to re-lock the hatch. All the BT equipment remains in place including WB1401, WB1410 filter unit, switching box, wiring and Tele-talk. The table, shelf, cupboard, rack of wooden shelves, wiring, light and one sign also remain in place. The Science Museum have considered finding a use for the bunker but have been unable to think of anything. During the 2002 National Heritage Open Weekend (Sep 14-15) the post was open to the public. Three former ROC observers were there, showing various items of equipment (the GZI, FSM and the triple maroon launcher, among things) and taking visitors into the bunker.
