It has been said that all 12 of the Poldark novels are going to be dramatised by the BBC following the success of the broadcast earlier this year. That makes Lantoom happy because it will give more exposure to its Caradon granite quarried near Liskeard, where some of the scenes are filmed.

“We were delighted the TV producers decided to use the area close to our quarries to film some of Ross Poldark’s more romantic scenes,” says Richard Crocker, MD of Lantoom. “The stone there is dramatic and beautiful.”

It is also “an easy way to add a little bit of Cornwall to your building project”, says Richard, who would be happy to sell you building stone from Caradon Quarry on Bodmin Moor.

In 2014 the stone was used in a Highly Commended selfbuild in the Sustainability category of the Natural Stone Awards.

And this year, as well as appearing on television, Caradon granite has been used to build an extension to Jamaica Inn, which gave its name to a novel by Daphne du Maurier that was subsequently made into a film by Alfred Hitchcock.
