History, Travel, Uncategorized, urbex

Kelvedon hatch is a cold war bunker built in 1952 to house approx 600 military and civilian personnel in the event of a nuclear strike. The bunker extends to 125 feet underground split over 3 floors hidden under a inconspicuous bungalow.

The audio tour lasts an hour or so and gives you an interesting and at times humorous look at how the bunker operated and what life would have been like in the event of a nuclear disaster.

After entering the bungalow its obvious that you are entering a secure site; metal cages and blast doors greet you as you march down the tunnel into the main heart of the site.

Snake?!? Snake?! SNAAAAKE!



Threats after a nulcear disaster come in many forms. The bunker was set up not just to keep government personnel safe from radiation but also from the civilian muties and raiders which would be after the food and resources after such an event!

Walking around the floors was like a step back in time; all of the technology and equipment was aged but in pristine condition looking like it was straight from the 80s.

LED’s weren’t invented until 1962 therefore the equipment in the bunker had some interesting bulbs. The below was from a radiation detector which monitored the levels outside of the bunker. Each number had its own filament.

This bunker was one of hundreds spread across the country, every district council had at least one nuclear bunker to ensure military and political persons would be safe in the event of a nuclear disaster to ensure that our democratic state could be maintained. Communication between these stations was vital to track the status and damage across the country.

Like every sci-fi and military film ever, these boards are actually used to plot bomb damage across the country. I couldn’t understand how these were easy to view!

Mapping the damage


Given the limited oxygen and water supply eventual someone would have to leave to assess the outside world and the damage caused. The best thing about radiation is humans can withstand a small amount without any physical effects. These Geiger counters would measure someone’s exposure on a trip outside.

  • 25 units= no signs
  • 50 units= might feel a little bit ill
  • 75 units= maximum human exposure recommended over a lifetime
  • 100 units= just a little bit dead


After its decommission in 1992 the bunker now serves as a great resource for film sets. The grudge 4 anyone?
