Mapped: The 284 UK nuclear bunkers you need to know about in case of WW3

Over the course of several decades, Britain constructed an extensive underground network of bunkers, encompassing anti-aircraft operation rooms, regional war rooms, subterranean Observer Corps posts, command bunkers, emergency centres and radar stations.

Some of these structures date back to WW2 and were retrofitted to withstand a nuclear apocalypse during the Cold War, while many others were specifically built to protect Britain in the event of a conflict with Soviet Russia during this period.

Cold war nuclear legacy.

Research conducted by Subterranea Britannica has revealed an astonishing 284 fallout shelters scattered across the UK, potentially providing refuge for a portion of the population in the event of a nuclear fallout. However, some of these are no longer operational.

This figure is an increase of eight from just a few months ago, as users of the site continue to uncover and document more forgotten nuclear bunkers, reports the Express.

Nuclear bunkers throughout Britain.

Among the most fascinating is Pitreavie Castle Combined HQ, a Scottish fortress that began its existence as a dilapidated fortified house.

Equally intriguing is Brislington War Room, discreetly located behind a humble government housing estate just two miles south-east of Bristol city centre.

Meanwhile, the Cambridge Regional War Room underwent a rebuild in 1963, with its new extension intended to function as one of three purpose-built Armed Forces HQs.

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

In a nod to the Cold War era, several of these shelters are situated on former RAF base sites.

Private bunkers up for grabs.

Basic garden shelters can set you back around £10,000, while high-end bunkers kitted out with cinemas, gyms and independent power supplies can skyrocket to over £3million.

Affluent clients scattered across the UK - particularly in London, Scotland and Wales - are seeking secure boltholes that can double as wine cellars or entertainment spaces.

With escalating tensions, private bunkers are emerging as a genuine lifestyle choice.
