When we envision the British monarchy, one of the first things that comes to mind is Buckingham Palace, with its gilded gates and changing of the guard. But it is Windsor Castle that can claim pride of place as the oldest and largest occupied castle in the world, dating to the earliest days of the monarchy, a symbol of strength and magnificence over a nearly thousand-year history of sieges and soirées alike. Witness to both great moments in the country's history and those that threatened to destroy it, the castle has become a symbol of English culture and architecture.
