Buckingham Palace, Windsor Castle and the Palace of Holyroodhouse - these buildings have been part of British royal history for hundreds of years. Presented by Fiona Bruce, The Queen's Palaces showcases the art and architecture, the interior decoration and the treasures stored inside these fabulous buildings and reveals the surprising and fascinating stories behind them. Combining Fiona's role as interested amateur with contributions from Royal Collection curators and experts, each programme offers a mix of high level insight and interesting and curious stories. In this episode, Fiona Bruce visits Windsor Castle, the world's oldest and largest inhabited castle, dating back to the 11th century. Taking more than a thousand years to reach its familiar look, it has been a fortress, a home to medieval chivalry, a baroque palace, and finally a romantic fantasy. From the bowels of the castle to the heights of the battlements, Fiona encounters all manner of royal treasures - from the musket ball that killed a naval hero to table decorations in gold and silver and encrusted with jewels; from the triple-headed portrait of a king who lost his head to Queen Mary's dolls' house with running taps, and a secret garden hidden in a drawer. All of this was almost lost in the disastrous fire of 1992.
