Countryfile: Blenheim Estate

John Craven and Margherita Taylor visit Blenheim Estate in Oxfordshire, where the 300-year-old palace is undergoing a once-in-a-lifetime conservation project.

Margherita heads up onto the rooftops to meet the craftspeople blending traditional skills with cutting-edge techniques, while John explores how the wider estate is being cared for, from protecting ancient woodland to growing new saplings in a forest lab and turning waste into mushrooms.

Back on his farm in the Cotswolds, Adam Henson prepares his Exmoor ponies, foals and donkeys for the months ahead.
