This structure began as a tunnel system in a quarry. During the Second World war it served two purposes; one section housed national treasures of great value. It was rumoured that the Crown Jewels were kept here with the area totally secure and even boasting one of the earliest smoke detectors. This area is now not accessible. Another area was used for the building of Royal Enfield motor cycles. The people who worked in both sections used a common entrance.
The Enfield section used for the motorbikes was one of the 'Shadow' factories protecting vital war efforts from bombing. Short Brothers, Rover and Enfield were the three main underground factories. They are known to us now as Shorts, Drakelowe, and Enfield. Enfield was still in use until the beginning of the 90's
