The birthplace of former British Prime Minister Sir Winston Churchill, Blenheim Palace is a world heritage site which is home to the 11th Duke and Duchess of Marlboro. The historic home is located on 2100 acres in Woodstock, 7 miles out of Oxford. It was a gift from Queen Ann to the first Duke of Marlborough after his grand victory in the battle of Blenheim in 1704. The video takes a tour of the home and its stately gardens on the day a huge triathlon was staged in the grounds. (Music used under licence from the Smartsound Quicktracks library).
