On Your Farm to visit Charles house
The Prince of Wales is opening the doors of his private house in Transylvania for a Radio 4 series, On Your Farm.
The show visits the farm in Romania for an exclusive interview, a two-part special to be broadcast this summer.
Radio 4 said: "He talks passionately about why he cares so much about preserving biodiversity and rural communities.
"He talks about why he thinks it is so important to preserve the rich meadows of Romania and create new ones in the UK, what we can learn from these Eastern European communities, and what should be done to preserve them."
Duchy tenant farmers and other organisations in the UK also talk about Charles's work on biodiversity and helping rural communities in the radio specials.
According to the Duchy of Cornwall website, Charles has visited rural Romania regularly since his first trip there in 1998.
He has bought and renovated properties there to help protect the unique way of life that has existed for hundreds of years.
In 2006, Charles decided to buy and restore an 18th century Saxon house in the Transylvanian village Viscri, a designated Unesco World Heritage Site.
In 2010, he purchased a property in the village of Zalanpatak which was founded four centuries ago as a glass manufacturing area in the heart of the forest.
