A Cold War nuclear monitoring bunker near Bristol is set to go under the hammer with a guide price of £20,000. Built in 1960, the Hallen ROC post was used by the Royal Observer Corps (ROC) until its closure in 1991.
The bunker, located in a hillside in Hallen, is accessed via a vertical metal ladder leading to a 128-square-foot room. It retains original fittings including a bed, desk, cabinet, and chemical toilet, though it lacks mains electricity and water.
The ROC manned 1,563 similar shelters across the UK during the Cold War, tasked with reporting nuclear attacks and monitoring fallout. After the Cold War ended, many posts were decommissioned and sold.
Auctioneers David Plaister describe the bunker as a 'well-preserved example' of civilian preparedness, suitable for use as a wine cellar, safe room, or secure storage. The auction is scheduled for 9 December.
Similar bunkers have attracted strong interest recently; one in Norfolk sold for £45,000 in May, while a Cumbrian bunker fetched £48,000 in 2023, more than triple its guide price.
