WW3 Mapped: The 284 UK nuclear bunkers YOU need to know about in case of atomic war

Britain spent decades developing an underground network of bunkers, including anti-aircraft operation rooms, regional war rooms, underground Observer Corps posts, command bunkers, emergency centres and radar stations.

Some of these date from WW2 and were converted to withstand nuclear armageddon during the Cold War, while many were newly created to defend Britain if it were to have gone to war with Soviet Russia during this time.

Cold war nuclear legacy

Since then, the Cold War ended, peaceful relations were established with Russia and many of the nation's defences against nuclear destruction were sold off or left to rot. However, a significant portion do remain operational and would be used in case of an atomic conflict with the recently aggressive Russian regime, or any other hostile state such as Iran, North Korea or even China.

Research carried out by Subterranea Britannica has uncovered a staggering 284 fallout shelters scattered across the UK - potentially shielding at least part of the public if nuclear fallout ever struck. Some, however, are no longer in service. This number is eight more than the site recorded just a few months ago, as users of the site discover and record more lost nuclear bunkers.

Nuclear bunkers throughout Britain

In major hubs like London, dozens of bunkers remain in place. Yet in more remote spots - including the Isle of Wight and the Isle of Man - there is only one shelter apiece.

Among the most intriguing is Pitreavie Castle Combined HQ, a Scottish stronghold that started life as a crumbling fortified house.

Equally eye-catching is Brislington War Room - tucked away behind a modest government housing estate just two miles south-east of Bristol city centre.

Elsewhere, the Cambridge Regional War Room was rebuilt in 1963, with its new extension designed to serve as one of three purpose-built Armed Forces HQs.

In Wales, Cardiff Coryton Regional War Room was strategically placed just off Junction 32 of the M4 motorway.

And, in true Cold War style, several others are set on the sites of former RAF bases.

Private bunkers available

Meanwhile, Britain's private bunker industry is booming as fears over war and unrest grow. Demand for underground safe rooms has surged by up to 400% in recent years, with firms like Subterranean Spaces and The Panic Room Company reporting skyrocketing interest.

Basic backyard shelters can cost around £10,000, while luxury bunkers fitted with cinemas, gyms and independent power supplies can top £3million.

Wealthy clients across the UK - especially in London, Scotland and Wales - want secure hideouts they can also use as wine cellars or entertainment spaces.

As tensions rise, private bunkers are becoming a serious lifestyle option.
