Established in the 11th century by William the Conqueror, Windsor Castle is the oldest and largest occupied castle in the world. It has been remodeled by a succession of kings and queens, including Henry II, Charles II, and George IV. Your ticket provides admission to the Castle, including the magnificent State Apartments, which are furnished with some of the finest treasures from the royal collection. Among the masterpieces are paintings by Holbein, Rubens, and Van Dyck, as well as fine English and French furniture. During the winter months, the sumptuous private apartments created by George IV, known as the Semi-State Rooms, are added to the visitor route. Your admission also includes access to St. George's Chapel (except on Sundays). This is one of the most beautiful ecclesiastical buildings in England, and is the final resting place for 10 monarchs, including Henry VIII and Charles I. There is a lot to see and do at Windsor Castle, so please allow enough time to make the most of your visit, which is likely to last between 2.5 and 3 hours. The Castle is situated at the top of a steep hill, and the visitor route covers long distances, so comfortable shoes are advised.
