New aerial photographs show the dangerous state of an underground cold war nuclear observation post clinging to the cliff face, as the North Sea and erosion threaten to topple it onto the beach. The building is now hanging 25ft over the beach posing a threat to anyone below.
The red brick building which is near Tunstall on the East Yorkshire coast is about 70 years old. It was created as a look-out post in the event of nuclear war.
It was one of 870 bunkers or observation posts across Britain, including eight in West Yorkshire that were decommissioned in the 1990s. Some of the buildings, including those in Yorkshire, were placed up for sale in the late 1990s.
The building would have had very limited facilities in it - no running water, toilets, electricity or windows. The bunker would have created a safe space for people to wait out a nuclear explosion, and communicate with others.
The decommissioned bunker, known as Tunstall ROC (Royal Observer Corps) was believed to have been built in 1959.
The rapid erosion on the East Yorkshire Coastline has left it exposed and vulnerable to collapse. Climate change has caused erosion, which is responsible for putting coastal properties, including underground bunkers, at risk.
