You were once required to sign the Official Secrets Act to enter the building, now it’s open for visitors to freely explore the immense bunker.
The labyrinth of rooms and offices is a precious time capsule and although the 300 war time staff have long gone, a visit to the museum will transport you back to that time and make you ask questions about the people who once worked there.
Today, the wartime bunker has been restored to exactly how it used to be and is open to the public as a memorial to those who died to save Britain and the rest of Europe. Visitors can take a step back into history to the original building where the battle was fought and won.
