Kelvedon Hatch Secret Nuclear Bunker

Kelvedon Hall Lane, Kelvedon Hatch, Brentwood, Essex, CM14 5TL

The biggest & deepest cold war bunker open to the public in the Southeast of England.

Come and witness the three lives of the bunker starting with its role as an RAF ROTOR Station, then a brief period as a civil defence centre through to its most recent life as a Regional Government HQ. Designed for up to 600 military and civilian personnel, possibly even the Prime Minister, their collective task being to organise the survival of the population in the awful aftermath of a nuclear war.

Bunker Tour:
The tour is self guided by personal handsets. This is included in admission price. There is an adult and child tour available which both follow the same route.
There are several films to watch en-route and a dressing up area where you can try on authentic military uniforms and gas masks!
As a rough guide the tour takes about an hour to an hour and a half to complete. However, should you stop to watch all of the included films and take some time out to try on the uniforms then this extends the tour by four hours. Some people find one tour just isn’t enough to take it all in!

The Bunker site is huge… and so we’ve a few other things you could consider doing when you are here.
