A Cold War nuclear bunker in the Norfolk Broads has been put up for sale for £10,000. 

The site in Church Road in Repps-With-Bastwick was one of the many observation posts built by the Ministry of Defence in the 1950s and 1960s for people to detect and report a nuclear disaster. 

The bunkers were designed to withstand radiation for the people inside and were fully equipped with radiological instruments.

Its main space, still equipped with a desk, is only big enough to fit three people.

Auction manager at Brown&Co, Trevor Blythe, said: “This is a rare opportunity to own a piece of British post-war history. 

“Observation posts like the one we are selling were built to provide protective, but extremely limited accommodation, for three observers in the event of a nuclear attack.” 

The online auction is set to open at 11am on November 12 and the bunker has a guide price of £10,000 to £20,000.
