The Bunker Below is a spine-chilling Halloween attraction held annually at the Kelvedon Hatch Secret Nuclear Bunker in Brentwood, Essex. This authentic Cold War-era facility, built in the 1950s as a potential government headquarters in the event of a nuclear attack, now serves as the backdrop for this unique horror experience.
Participants embark on a nearly hour-long journey through the bunker, navigating pitch-black tunnels, eerie illusions, and encountering live actors portraying terrifying characters. The narrative centres around a mysterious signal that induces hallucinatory states, plunging visitors into a nightmarish reality.
The event is designed for thrill-seekers aged 16 and over, offering a blend of psychological and physical scares that make it one of the UK’s most intense haunted attractions.
