More information : SD 055 990. An Explosives Factory for the manufacture of Trinitrotoluene (TNT) was constructed at Drigg during the second world war by the Royal Ordnance Factory organisation. The factory cost £2.5 million and production was underway by April 1941. It sat on the coastal plain between the sea and the railway line immediately to the north of the mouth of the river Irt. The factory was relatively small and reflecting its hazardous activity most of the production buildings were heavily traversed. For the sake oF efficiency all ancillary buildings were centralised. Detatched hostels to accommodate the workers were situated at Millom, Silecroft, Stanley Ghyll YHA and Holmbrook. The factory was closed in August 1945 at VJ+1. It is believed that the site has been developed as a low level nuclear waste dump for the Sellafield nuclear complex. (1-1c)
