Former Devon and Cornwall industrial sites 'at risk'
A former Cornwall mining site is among 47 historical sites in the South West claimed to be at risk.
English Heritage says overgrown vegetation is damaging Carlyon Farm clay drying works at Treverbyn.
The kiln has not been used for more than 50 years, with overgrown vegetation causing serious damage.
It says other sites have been saved by being converted into modern industrial units while protecting their architecture.
It cites the clay dries at Wenford near St Breward which could be turned into flats and work units and Robinsons Shaft mining complex in Cornwall which is being converted into a heritage centre.
Andrew Vines, English Heritage planning director in the South West, said: "Britain led the way in global industrialisation and as a result we are custodians of the world's most important industrial heritage.
"It is, however, one of the elements of our heritage most at risk."
