The Secret Nuclear Bunker at Kelvedon Hatch, in the Borough of Brentwood in the English county of Essex, is a large underground bunker maintained during the cold war as a potential regional government headquarters. Since being decommissioned in 1992, the bunker has been open to the public as a tourist attraction, with a museum focusing on its cold war history.
When you get there and walk through the trees the first thing you see is this unassuming bungalow with this plaque outside:
Not sure what this is but it was outside the bungalow:
It's £7 for adults, £5 for children and to take pictures inside you have to pay £5 which I did.
I'm not going to say much about the bunker I'm just going to let the pictures do the talking.
