Heritage watchdogs have today unveiled a register of historical buildings facing neglect in the South West while appealing for help to add more to the list.
The English Heritage At Risk Register reveals that although eight Grade I and II* buildings have been saved across the region, a further 15 have been found to be in danger.
For the first time the organisation plans to expand the register by adding Grade II listed buildings facing ruin.
With 82,264 Grade II buildings in the South West, accounting for 91.9% of all listed buildings, Heritage chiefs say they need help assessing them.
Andrew Vines, planning director for English Heritage in the South West, said Grade II listed buildings were the bulk of the South West's "heritage treasury."
He said: "When one of them is lost, it's as though someone has rubbed out a bit of the past – something that made your street or your village special will have gone.
"We need help from local authorities, national parks, heritage and community groups to find the most efficient way of conducting such an exercise. We're prepared to fund nine to 15 pilot surveys around the country.
"For local authorities hard-pressed by cuts or other groups who come forward, this means money to find out which buildings most need their scarce resources.
"It will help all parties involved, including the Heritage Lottery Fund and other grant-givers, to get rescues underway where nothing has been happening for years."
Grade II buildings known to be at risk include Harvey's Foundry, Hayle, west Cornwall, where 80% of the world's steam pumping engines used to be made.
Of the 15 new buildings added to the register, three Grade II* buildings are at the King Edward Mine in Troon, Camborne, west Cornwall.
It is the most complete surviving mine-head complex in the Cornwall and West Devon Mining Landscape World Heritage Site.
Eight of the 15 sites lie in Cornwall including Treffry Viaduct, Luxulyan near Bodmin, and Rosewarne House (Gladys Holman House), Camborne.
In Devon five made it onto the list including the former stables at Stover House, Stover near Newton Abbot, and Exeter's Devon and Exeter Institution.
