English: Former Site of RAF Chilmark. This is an entrance to the former ammunition and bomb depot of RAF Chilmark and shows a possible guardhouse with another building beyond. This picture is taken from the bridleway that runs between the nearby Ham Cross to Chilmark unclassified road and the village of Teffont Evias.

Chilmark Quarries and its underground limestone mines about 500m to the north, and the surrounding land, were acquired by the Air Ministry in 1936 and served as a bomb store, RAF Chilmark, throughout WWII. The depot had a narrow gauge railway, 906101, and there was a transfer station at Ham Cross 1km to the south with a 4km spur from the main line at Dinton. The first consignment of war stores arrived in May 1937. There were also immense surface storage bomb and ammunition dumps in other locations in the area, particularly in Grovely Woods about 7km by road to the north-east, see one of the concrete roads from Chilmark to the bomb dumps, 884965.

Unlike most other RAF depots, Chilmark continued in use after the war. In 1994 supplies were transferred to the Nato depot at Glen Douglas in Scotland, prior to the complete closure of Chilmark in April 1995 with the loss of 200 jobs. Since then the site has been cleared of explosives, and much of the land towards Dinton has been sold off. In 1985 a bunker was built in the southern part of the site to serve as a Regional Government Headquarters, see http://www.subbrit.org.uk/rsg/features/sfs/file_11.htm, but this was decommissioned and sold in 1997.

Much of the site around Chilmark Quarries remains in Ministry of Defence ownership, and includes two Sites of Special Scientific Interest (SSSI), see 906068.
