Drakelow Tunnels are a former Top Secret underground military complex beneath Kingsford Country Park north of Kidderminster, Worcestershire. The tunnels were built between 1941-1942 as a Shadow Factory for the Rover car company. Parts for aircraft engines were machined in the 3.5 miles of tunnels throughout WWII. After WWII the tunnels began producing parts for tank engines until 1958 when the tunnels were handed over to the Ministry of Supply, and later Ministry of Works.
In 1961 the British Government converted half of the tunnels into a top secret facility, designated: Regional Seat of Goverment 9 (R.S.G. 9). Drakelow, along with 12 other facilities scattered across the U.K. formed a national network of highly classified Nuclear Bunkers, that the British Goverment would operate the country from, in the event of Nuclear War.
