Windsor Castle, London

This castle, which is located in Berkshire just outside London, is the official residence of the Queen of England and is still used by the royal family as a weekend home. In addition, many state banquets and other official events are still held at Windsor Castle. Travelers to Windsor, which is the largest and oldest occupied castle in the world, will find plenty to see. If the weather permits, they can enjoy watching the famous Changing of the Guards, or they can take part in one of St. George’s Chapel’s daily worship services.
