Radio Times are celebrating the best of TV, radio and books with a host of stars and TV insiders appearing on The Green at Hampton Court Palace for the Radio Times Festival. Every ticket includes access to gourmet food stalls, a shopping village, free events and screenings. For this event, acclaimed historian Simon Schama discusses his two great passions: British history and art history. With an accompanying five-part BBC TV series, book and special displays at the National Portrait Gallery he embarks on a landmark journey of discovery, exploring the history of our nation through its portraits. Few people are as wizened up on our country's past as Mr Schama, and this is one of the few chances to speak with him. Snap it up. Under 5 years go free, but must be seated on parents lap. Over 16s must purchase an adult ticket.
