Jonathan's journey takes him to Burghley House in Lincolnshire. Built to impress Queen Elizabeth I on her many trips around the country, it's the finest example of an Elizabethan house in Britain. With unprecedented access to Burghley, Jonathan, aided by champion climber Lucy Creamer, climbs the building, to reveal the innovations of the Elizabethan builders and craftsmen. On his adventures, Jonathan scales up to the roof of Burghley to reveal a unique playground of hidden ornate sculpture where royalty and ambassadors were entertained. He also zips 80 feet across the central courtyard to decipher the scores of mysterious symbols that adorn the building, and scales over a hundred feet to come face-to-face with a one-handed clock. Finally, Jonathan reveals why, although the house was built to accommodate Elizabeth I and her court, she never even set eyes on it.
