Last week I went to Hack Green Nuclear Bunker near Nantwich in Cheshire.
There were many interesting things there including: mock ups of cold war rooms; a decommissioned nuclear warhead; decommissioned nuclear bombs; radio equipment; uniform displays and lots more.
In 1941 during World War 2 the site was chosen to become RAF Hack Green. Hack Green was one of 21 fixed radar stations. Following World War 2 the bunker was fitted with new long range radar as part of our defence against nuclear attack.
I enjoyed my visit and found it very informative. Hack Green's website is here: http://www.hackgreen.co.uk/index.htm
