Blenheim Palace: Behind the Grandeur

It's Spring in Oxfordshire, and at 300-year-old Blenheim Palace, the staff prepare to open for another busy season. The Palace, a private residence of the 12th Duke of Marlborough, is the only non-royal Palace in England, and opened its doors to the public in 1950 in order to raise funds to conserve and maintain the Palace and its estate - and it's always busy for the staff who welcome nearly a million visitors a year. Prepare to step into the dazzling grandeur of one of Britain's most spectacular palaces.
