On a low mound in an ‘L’ shaped compound at the end of a long line of telegraph poles 200 yards North East of In Moor Lane (undrivable farm track/bridleway) and one mile North West from the end of the road in Middlesmoor village.
LOCKED Compass bearings are painted on the compound fencing. All surface features are intact and in good condition as is the white and black (pipes, louvres and hatch) paint. This was one of 6 posts containing seismograph equipment (the others being Barham (Kent), South Creake (Norfolk), Lampeter (Cardiganshire), Llanuwchllyn (Merionethshire) and St. Breward (Cornwall). When questioned about these seismic stations in 1994 the public relations officer at AWE Aldermaston said “These form a part of the Ministry of Defence network of seismic stations used in connection with nuclear test ban verification. We have 6 seismic stations at former ROC sites. The use of the present tense would suggest that these stations were still operational. When inspected in 1994 the post at Barham (Kent) was empty and open although it is now locked. When the South Creake Post (Norfolk) was inspected in 1998 the seismic equipment and batteries were still there and operating. A local farmer said the post is still visited by government officials every couple of years adding that they stay in the village for two days.
Opened in 1959 and closed in 1991.
