A two-storey underground nuclear bunker with 56 bedrooms has gone on sale for £435,000.
Hope Cove Bunker near Salcombe, Devon, was built as a WW2 radar station in 1941.
Maps which would have been used to co-ordinate a response to an attack remain in the old operational room.
Soundproofed radio stations are also still features of the bunker.
The bunker was redeveloped in the 50s as a regional government base in case of a nuclear attack in the Cold War.
It was on standby until the 90s, ready to accommodate 250 workers in the event of a Soviet attack.
Interesting footage released shows the inside and outside of the historic bunker and a preview of the surrounding land.
Christopher Howell, caretaker of the bunker, told Sky News : “It was designed to be sealed up, a recycled air system was running – and had anything radioactive come this way, that would have offered them some protection.
“The idea was had the bomb gone off they would all congregate here, they would shut down inside, they have enough oil in tanks run generators for 35 days.
“The place was highly secure, people were here 24/7, it was kept fully operational, all systems were kept so they could be brought fully into use if a bomb went off.”
Clive Emson Auctioneers said people have been interested in the space as possible use for cheese or wine storage.
A representative said others have considered it as a community space for the arts.
Others have thought about it as a hotel, according to reports.
Many who have gone to visit the unusual property have reportedly been from the RAF.
