The UK has shown images of one of the most secret Cold War bunkers for the first time

In the early 1950s, amid the growing threat of nuclear attack from the Soviet Union, British authorities decided to build underground bunkers to protect and ensure the continuity of government operations in the event of a nuclear conflict.

Over time, the scope of the project expanded considerably. The bunker became a huge complex capable of housing up to 400 civil servants, providing them with a self-contained existence for an extended period of time.

Daily Mail journalists recently gained access to exclusive photographs of the classified facility, which for the first time give a glimpse inside one of Britain's most secretive Cold War sites.

The images show the narrow corridors and cramped rooms of the bunker: a kitchen where food was prepared for the inhabitants, an infirmary with medical equipment, warehouses with food and water supplies, and a BBC recording studio for emergency messages to the public. You can also see the spacious halls where officials could continue their work despite external threats.

The interior details are of particular interest. In the toilet rooms, rolls of toilet paper with the inscription "Property of the Government" on each sheet have been preserved, which emphasises the level of secrecy and importance of the facility. These little things allow you to feel the atmosphere of that era and realise how seriously the state was preparing for a possible catastrophe.
