On a low hilltop close to trig. station, 50 yards north of a farm track and 150 yards west of an un-named minor road.
DEMOLISHED When visited in 2002 only the access shaft remained intact and partly covered with soil. The ventilation louvres and the hatch are missing but access is not possible as a large rock has been jammed in the shaft. The demolition of the other surface features appears very recent. High concrete fence posts along two sides of the former compound are still in place. By 2011 the post had been demolished.
Opened in 1961 and closed in 1968.
