Hasting Hill, Royal Observer Corps Post

Post 2 in cluster E of 30 Group moved here in or before May 1949 from a site in Washington (HER 5881). In December 1952 the post was resited back to its original base at Washington (HER 5880). At some time after 1952, as part of the general reorganisation of the ROC during the Rotor period, the post was resited back to Hastings Hill, a ground level Orlit post was required for this resite. In or before June 1959 the post moved underground. In or before October 1968 it was renumbered post 1 in cluster H of 23 Group. This was a visual observation post to track aircraft movements. Early Observer Corps Posts had a simple instrument for plotting the plan position of the aircraft. Throughout WW2 the ROC had a more sophisticated "Post Instrument" which also recorded the height of the aircraft. WW2 posts were frequently simply sand bagged emplacements, or more sophisticated examples were of domestic brick construction, some two-storey, with an open observation post and a crew room. Some had latrines.
