The recently unveiled Cold War bunker in Bridgend, Wales, is an apt reminder of the UK government's precarious nuclear preparedness during the era. Conceived as a vital command centre for governing the nation in the aftermath of a nuclear attack, this subterranean structure has been found to be surprisingly vulnerable to the very dangers it was designed to mitigate.
Located beneath an unassuming hill adjacent to a modern housing estate, the bunker occupies two of seven tunnels excavated during World War Two for storing munitions from the nearby Royal Ordnance factory. Despite its imposing exterior, those who have maintained the site since the 1990s have raised concerns about significant design weaknesses that would have rendered it largely ineffective in a genuine nuclear emergency.
A critical vulnerability lies in the storm drain running directly through the tunnel from the outside, which could have channelled radioactive debris into the bunker via this drain. The internal water supply for drinking and washing was installed perilously close to the open drain, raising serious concerns about potential contamination. The manager noted that such a fundamental oversight seemed not to be considered during its construction.
Comparisons with other UK government-built Cold War bunkers highlight the Bridgend facility's inferior design. For instance, a bunker in Essex features a long, indirect corridor leading to its entrance, offering better protection against a direct nuclear blast. The Bridgend bunker's more direct entry path was highlighted as a significant disadvantage.
Today, the site has found an unexpected new purpose. Beyond its historical significance, the bunker is frequently used as a filming location for various television series and films, including popular productions like 'Doctor Who' and 'The Pembrokeshire Murders'. It has also served as a storage facility for evidence by South Wales Police, demonstrating its adaptability long after its original purpose faded with the end of the Cold War.
Historian Brett Exton, 59, who visited the bunker in the early 2000s, described the experience as akin to being in a vast hospital, with numerous rooms branching off a seemingly endless corridor. He noted that one room, which had served as a dormitory, still bore the outlines of beds, offering a tangible link to the bunker's past as a potential last refuge for a select few.
