A once-proud nuclear bunker perched on a clifftop in East Yorkshire has tumbled into the sea after years of relentless coastal erosion. The Tunstall Royal Observer Corps building, which had stood for nearly seven decades, is now being washed over by waves, marking the end of its storied existence.
Decades of Coastal Erosion Take Their Toll
Located at Tunstall, the red brick building was constructed in 1959 as part of the UK’s network of nuclear monitoring posts. Designed to assess the impact of nuclear detonation and radiation fallout, the structure served a vital role during the Cold War era. However, after its decommissioning in the early 1990s, it became a relic of history, left to face the elements.
For years, the coastal cliffs at Holderness, where the bunker stood, have been eroding at a rate of 6.5 feet per year. The Environment Agency has warned that the ongoing erosion would eventually lead to the fall of coastal structures, and the bunker’s collapse into the sea on January 25, 2026, serves as a stark reminder of the land’s vulnerability.
Amateur historians Davey Robinson and Tracy Charlton, who have closely documented the gradual demise of the bunker in a series of YouTube videos, expressed deep emotional attachment to the building’s legacy. “It’s not just bricks and mortar, it’s something else,” Robinson shared. His ongoing documentation aims to preserve the story of the bunker and its eventual fate.
Public Safety Concerns Amid Erosion
Despite the fascination surrounding the bunker’s collapse, East Riding of Yorkshire Council has issued warnings for the public to stay clear of the eroding cliffs, which have become increasingly hazardous. The former bunker stood on privately owned land, though it remains part of the council’s shoreline management plan.
Officials emphasized that the coast is undefended in this area, allowing natural coastal processes to continue, and that the Ministry of Defence had originally requisitioned the land for military use. After the bunker’s closure, the land was returned to the landowner along with any remaining infrastructure.
The tragic loss of this historic structure brings attention to the ongoing impact of coastal erosion on the region, with the future of similar buildings uncertain as nature’s forces continue their relentless march along the Yorkshire coastline.

Just to polish off some rough edges.
“A once-proud nuclear bunker” – the structure was underground (the clue is in the word ‘bunker’) and unseen from 1959 to 2024. It had not really ‘stood’ and was only made to ‘face the elements’ since the latter date.
“years of relentless coastal erosion” and “For years, the coastal cliffs at Holderness…have been eroding” – those years number over 10,000.
“eroding cliffs, which have become increasingly hazardous.” – the cliffs of East Riding of Yorkshire are no more hazardous than they have been for centuries of human experience.
Military wartime defence structures constructed along the coastal area, notably pillboxes, but sometimes much larger (e.g. the batteries at KIlnsea and Ringbrough), have and continue to succumb to cliff recession. Many slide or tumble to the beach without attracting any attention.
