A nuclear bunker, used to monitor radiation levels in Cumbria at the height of the Cold War, is up for sale.
The bunker was decommissioned in the early 1990s
The decommissioned Royal Observer Corps bunker at Bell Mount Farm in Skirsgill near Penrith, is to go under the auctioneer's hammer on Thursday.
At 15ft (4.6m) deep, it boasts carpeted floor, chemical toilet, a chair, cupboards and a first aid box.
It is being sold, together with the 18-acre plot of land in which it stands, at a guide price of £90,000.
Bruce Murray, of auctioneers Penrith Farmers' and Kidd's, said the bunker was used from the 1950s to detect nuclear fallout from potential Soviet missile attacks.
He said: "Nothing has got damp down here, the carpet is dry.
"The only thing is that it is dark as the battery electric system is not working anymore.
"It does not have a use other than novelty value. There is not many around and you will own a piece of history.
"The land is the main attraction for the sale and the bunker is a little bonus."
The bunker, which is about 7ft (2.1m) wide and 12ft (3.6m) long, was decommissioned in the early 1990s.
