Built beneath the ground to a depth of 125 feet, Kelvedon Hatch Bunker was constructed in 1952 and was originally intended to house military personnel, skilled civilians and perhaps even the Prime Minister in the event of a nuclear attack. Situated in the middle of dense Essex woodland, the bunker wasn’t made public knowledge until 1992 when it was decommissioned.

The areas of the bunker with most reputed activity are the generator rooms, the dormitories and the medical rooms. They are all said to be very active, with many reports of ghostly figures seemingly approaching you, poltergeists and many other occurrences.

Reported Hauntings:

We feel that this is one of the best locations to carry out a public paranormal investigation. Kelvedon Hatch offers a truly unique experience with the fact that it’s situated in the middle of nowhere, and lies 125 feet beneath the ground! With only a small unit building visible above ground, below there is an expansive facility that harbours several unnerving spaces that are deemed to be very active. Even hardened investigators are said to refuse to walk these corridors alone!

The location has a vast history of the paranormal. One story comes from the time when the bunker was first being built. During initial construction, the facility required tons and tons of concrete, which was being poured 24/7 for a number of weeks. One morning, workers found on site a foreman’s hat that was found sitting on the wet concrete but the man was nowhere to be found, it was assumed that he was buried in the very walls that he was helping construct.

It’s also known that there was ancient burial ground dug up during the construction of the facility, there was also believed to be a suicide by one of the workers on the main stairwell.

During the years there have been many paranormal reports at Kelvedon Hatch. Perhaps the most common occurrence is poltergeist activity, with many first-hand accounts of things being thrown. There are also reports of full-bodied apparitions that appear throughout the location. Growls and thumping sounds have also been heard. A malicious spirit is also reported to be wandering the service tunnels.
