The heir to the throne has taken court action against the owner of Wheal Roots Tin Mine – known more recently as the Poldark Mine – over unpaid rent on the lease of the underground passages that make up much of the tourist attraction.
The Duchy of Cornwall – the body which handles Charles’ land and property portfolio – is the legally registered owner of the mineral rights at the mine, as it is at other sites around the county, according to legislation dating back to 1844.
David Edwards, 71, argues that the fact the site is no longer used for extracting resources beneath the surface, but is instead an open-air museum, means the Duchy should not have ownership.
However, he admits he signed a lease agreement when he took over the site, which lawyers for the Duchy are using to enforce the payment of rent.
His refusal to do so resulted in two County Court Judgments being filed against him, meaning he faces debts of more than £40,000 including solicitors bills.
The mine, which operates within a World Heritage Site, and has been a popular visiting spot due to its connections with the BBC drama, has been closed for three years amid the wrangling.
