Mortimer & Whitehouse: Gone Fishing

Harry Hill's World of TV

George Clarke's National Trust Unlocked

Sunday, 9pm, Channel 4

"George discovers some of the UK's most impressive historic homes, as he is granted special access to some of these extraordinary places, delving into the hidden recesses that visitors don't normally get to see. In this first episode, George's journey begins in Dorset at the UK's most exquisite example of Italianate architecture - the magnificent 17th-century Kingston Lacy. He uncovers a tale of shame and scandal on the south coast, and the beautiful Cotswold landmark - Hidcote Manor Gardens - in full bloom takes his breath away. George also mines the history of the country's last cave dwellers at one of Britain's best-kept secrets, the Rock Houses at Kinver Edge, and finally, with his husky Loki, takes a walk at spectacular Studland Bay, part of the Jurassic Coast World Heritage Site."
