Site Visit carried out by Subterranea Britannica (S2). Noted that all surface features remain intact, but one side of the hill has been cut away and a door and window has been added to the monitoring room. The hatch has also been welded shut. The only original internal fitting is the folding table. This site visit also records an 'Orlit A' post a few yards to the North.
