The Secret Bunker houses a number of rooms which acted as a command centre during the Cold War.
There is a complete reconstruction of The Royal Observer Corps Dundee HQ which would have been used to report the locations of bomb drops, measuring the power and pressure of the detonation. This information would then assist the services in evacuation of civilians as well as resources such as food, medicine and retaliation.
The radar room displays some of the equipment that was among the last to record interceptions of Soviet incursions into British air space during the final days of the Cold War.
The RAF operations room is complete rebuild of the original 1950s RAF centre which was housed at this site. This room includes a "Tote" board which shows aircraft and anti-aircraft gun status, as well as original files and papers which were left behind after the end of the Cold War.
