Coal mining Lochinvar coalfield was discovered in the 1950s by the
National Coal Board and was subject to drilling but never mined. From 2014 an Australian firm was exploring the coalfield for coking coal to produce steel. The company was exploring as far north as Evertown near
Canonbie, and as far south as Longtown.
DMC Longtown During the 1930s, there was a recognition of a need to provide secure storage for munitions across the
United Kingdom. The proposal was to create three Central Ammunition Depots (CAD): one in the south (
Monkton Farleigh,
Wiltshire); one in the Midlands (
Nesscliffe,
Shropshire); and one in the north. While the other two sites were sat above easily hewn
limestone, Longtown is located above
granite, which meant that it took longer to create and only came into operations late in the
Second World War. The site was chosen as it used to be part of
HM Factory, Gretna, that stretched to
Eastriggs over the border in
Scotland, one of the biggest makers of explosives during the
First World War. The township of
Gretna was established to house the workers of this establishment. Today, DMC (
Defence Munitions Centre) Longtown is the only one of the three CADs to remain in operation and is among the largest defence munitions sites in
Western Europe. Currently, Longtown and Eastriggs are two separate sites under joint management. In November 2013 the
MoD announced that the operational capacity of MoD Longtown would be reduced and a small area of the site would be given over to commercial use. ==See also==
