No trip to London would be complete without seeing Buckingham Palace, the official residence of the British monarchy. Visitors can watch the Changing of the Guard ceremony, which takes place daily at 11:30 am, or take a tour of the palace to see the State Rooms and other areas not usually open to the public.

For those interested in art, the National Gallery and the Tate Modern are two must-see museums. The National Gallery houses an impressive collection of Western European paintings from the 13th to the 19th centuries, while the Tate Modern is home to modern and contemporary art from around the world.
