At the time, this explore seemed relatively boring – it was basically a lot of empty sheds and buildings. However, the site is historically significant, even more so now it’s been demolished. Wikipedia has this to say about ROF Elstow (amongst other things):
Royal Ordnance Factory (ROF) Elstow was one of sixteen UK Ministry of Supply, World War II, Filling Factories. It was a medium-sized filling factory, (Filling Factory No. 16), which filled and packed munitions. It was located south of the town of Bedford, between the villages of Elstow and Wilstead in Bedfordshire. It was bounded on the northeast by the A6 and on the west by a railway line. Hostels were built nearby to accommodate the workers who were mostly female.
It had 250 buildings and 15 miles of standard gauge railway lines. It was linked to the Midland Railway line running between London and Bedford.
ROF Elstow started filling munitions in February 1942.
ROF Elstow closed in 1946. The CEGB took over the site in 1969 with the intention of building a power station but this never came to fruition.
Here are a few external photos – the combination of emptiness and half-demolition meant that I wasn’t feeling particularly inspired inside.
