A nuclear bunker from the Cold War era in Britain was sold on eBay for more than 20,000 pounds (30,000 dollars, 22,000 euros) today.

The underground bunker in the Peak District of Derbyshire, central England, went on sale at a starting estimate of 500 pounds on Thursday, but more than 40 bids sent the price tag soaring.

The bunker came into service in 1959 and was used by the Royal Observer Corps, a civilian defence organisation composed mainly of volunteers who had the task of reporting nuclear attack and fallout.

According to the seller, the bunker is in an "elevated position with panoramic views" of the Peak District.

Built 15 feet (4.5 metres) underground on farmland, the shelter comprises of two rooms -- a chemical toilet and monitoring room -- and two ventilation shafts.

"A rare opportunity to acquire a piece of Cold War history," the seller added. "Your own nuclear bunker within a plot of land and much original equipment.

As well as furniture, the buyer will also receive a siren box, enamel bucket, jerry cans and rope for hauling heavy items up the shaft.
