The Bunker Entrance
The Mast is the only thing visible from the air that would have been a clue to a hidden bunker deep beneath the Essex countryside.
The Bunker tour starts at this simple bungalow, originally built in 1952 by the Air Ministry and modified later. The Bungalow guards the entrance to the Bunker.
Just inside the bungalow is a 120m long tunnel which leads into the main bunker. To the left of the bungalow are the standby generators with enough fuel to run continuously for 3 months. The bungalow and tunnel are heavily reinforced, and serve mainly as protection from the blast and radiation of a Nuclear Bomb.
