Description

Kelvedon Hatch Secret Nuclear Bunker, Great Britain. Public Domain.

The Kelvedon Hatch Secret Nuclear Bunker is one of those secret bunkers, located under an inconspicuous looking bungalow. The bunker is protected by 3 m reinforced concrete and blast doors made from tank metal. The bunker had four different usages during his history:

  1. an RAF ROTOR Station for the defence radar system.
  2. a civil defence centre.
  3. a Regional Government HQ to run the region in the event of nuclear attack.
  4. a tourist attraction.

Like many other bunkers it was abandoned after the Cold War and turned into a tourist attraction. A funny story is the change in owners: The land to build the bunker was requisitioned from the local farmer J. A. Parrish. But when it was decommissioned, it was bought back from the government by the Parrish family, at a closed bid public auction. So they got their land back and are now owners of a nuclear bunker.

The bunker is accessed through a simple bungalow, originally built in 1952 by the Air Ministry. From this "harmless" building a 120 m long tunnel leads into the main bunker. This is the lowest of three levels, at 25 m depth, containing communication and plant equipment. The second level is the government level. The top level contains a small surgery, several washrooms, dormitories, and a large canteen.
