David Dimbleby journeys through Britain, and through 1,000 years of our history, to discover the buildings that have made us who we are. Dimbleby explores the great country houses of the reign of Elizabeth I. He reveals the exquisite forest of chimneys on the roof of Burghley House, decodes the riddle of the mysterious Triangular Lodge, explores priest holes, knot gardens, a hunting lodge and Shakespeare's schoolroom, ending his journey in a rare Puritan chapel.
