Underground monitoring post built to monitor nuclear bomb explosions and the drift of fallout. Built in 1960 it was closed in Septemebr 1991. It is locked and in good external condition. In 1994 the site was visited and paperwork removed and given to the ROC Museum. One of the papers refered to routine checks for UKNET seismograph equipment as it was used at one stage for nuclear test ban verification. (1)

By 1925 there was a Royal Observer Corps observation Post at Barham (designated 1/C2), beside a track to the east of Upper Digges Place. In late April 1941 this was listed as falling ‘within the perimeter of a home guard defended area’. After the Second World War it was replaced by the present, exceptionally well-preserved, underground post, on the same site. It is not yet clear whether anything survives of the Second World War post.
