With Britain's country houses being home to world-class art collections full of priceless old masters and more, this three-part series sees art historian Helen Rosslyn tell the story of how great art has been brought to Britain by passionate collectors and how these same collectors have also turned patron and commissioned work from the cream of their contemporary crop of painters.

In this episode she focuses on the 18th century, the Grand Tour era when aristocrats filled their Palladian villas with masterpieces by 17th-century classical painters. Throwing open the doors of some of our most magnificent stately homes, Rosslyn visits Holkham Hall in Norfolk to view the Grand Tour collection there, before going on to explore the legacy of the Dukes of Richmond at Goodwood House. She also visits Petworth House in Sussex, where the one-time Lord Egremont patronised JMW Turner. Show less
