Life at the Oxfordshire mansion, a 300-year-old Baroque property set in 2,000 acres of Capability Brown-designed parkland, boasting the most extensive collections of portraits, furniture, sculpture and tapestries in Europe. For the first time cameras have been given unprecedented access to its most important season - Christmas. Around 250,000 visitors are expected to flock to marvel at the breathtaking state rooms and sprawling grounds transformed into an unrecognisable winter wonderland. The palace's army of staff, volunteers and specialist teams have under three weeks to install seasonal cheer on a colossal scale.
