The second day in London was filled with a sightseeing tour of some of the famous landmarks like the Houses of Parliament, Big Ben, Piccadilly Circus, and Buckingham Palace. The travelers also visited St. Paul's Cathedral and watched the ceremonial pageantry of the Changing of the Guard. The photo shows the beauty of Windsor Castle, the oldest and largest inhabited castle in the world. It's history spans more than 900 years.
The castle covers an area of about 13 acres and contains a church, homes and workplaces for many people, as well as the royal palace. The State apartments are used regularly by the Queen and the Royal Family for ceremonial and State occasions. The rooms are furnished with valuables from the Royal Collection, including masterpieces by Rembrandt, Holbein, Canaletto, and Van Dyck.
