Overview
- The Tunstall Royal Observer Corps post, built in 1959 and decommissioned in the early 1990s, now sits at the cliff edge above the North Sea.
- Waves reach the structure at high tide after recent storms undercut the clay, and a sudden collapse is expected.
- Amateur historian Davey Robinson, documenting the site with Tracy Charlton, says the bunker may have only a few days left.
- Their daily videos have drawn thousands of views as more of the once-underground brickwork and interior sections become visible.
- The Environment Agency says the Holderness coast loses about two meters of land each year, putting coastal heritage at persistent risk.
