Description

ROYAL OBSERVER CORPS ORLIT A POST (ST 49994 50765)

Orlit Type A Post, erected in 1953. One of two standard designs manufactured by Messrs Orlit Ltd for the Royal Observer Corps.

Description: it is constructed of pre-fabricated concrete panels that have been bolted together, with a concrete slab roof over the southern section; the rest of the structure originally had a removable corrugated steel roof cover but this is missing. It is rectangular on plan, measuring approximately 3.05m by 2.03m. At the south-east corner is a low entranceway (door is missing) which leads into the narrower, roofed section which was used as a shelter and store. To the right, a lower doorway provides access from the sheltered part into the former open observation area which housed instruments and charts. The interior has been completely stripped.

ROYAL OBSERVER CORPS UNDERGROUND MONITORING POST (ST 50004 50782)

A Royal Observer Corps underground monitoring post of 1961. Built to a standard design of 1956 by the Air Ministry Works Department.

Description: the former monitoring post is set within a compound marked by concrete posts and a metal gate. It is built of reinforced concrete with a compacted earth covering and has a roughly rectangular plan. It takes the form of a low, elongated mound with a raised, concrete entrance hatch towards one (west) end and a smaller, raised concrete ventilator towards the other end. Between these two openings is a single metal pipe that was the mounting for the fixed survey meter probe. The mounting for the Ground Zero Indicator (a pinhole camera device for detecting the direction and altitude of nuclear explosions) is adjacent to the entrance hatch. The entrance hatch has been boarded over and the underground chamber has been completely infilled with earth and rubble.

The structures associated with the radar testing that was carried out in the area during the second half of the C20 which include which include a corrugated hut, a disused winch and several concrete blocks are not of special interest.
