Ellie Harrison visits the historic Sudeley Castle in Gloucestershire, which is hundreds of years old and has seen many kings and queens of England pass through its doors. Ellie finds out what it takes to be a tour guide at the castle; she has to learn her facts, as she is due to lead the final tour of the day. Ellie finds out about the history of the castle including how Henry VIII's widow, Katharine Parr, came to be buried in the church there. She also takes a tour of the gardens and meets garden designer Sir Roddy Llewellyn to find out what he has in store for the historic gardens. She meets some of the feathered residents who now live at the castle, from barn owls to snowy owls, and from eagle owls to a rare collection of pheasants. Throughout the programme, Ellie delves back into the Countryfile archives to dig out some of the best stories which showcase our country's rural architecture. Matt Baker explores the bastle houses of Northumberland, Julia Bradbury meets the resident of a Fog House on the Anglesey coast, and John Craven is with a harpist in the Mussenden Temple in Northern Ireland.
