London is a huge city with a lot of history and an outstanding collection of world class tourist attractions. 

	London attractions include the London Bridge and the nearby Tower of London with its colourful "Beefeaters". Among other must-see sights are The Houses of Parliament and the famous Clocktower, that houses Big Ben. Buckingham Palace is open to visitors in August and September, but the changing of Guard and the Horse Guards Parade can be seen all year round. St. Paul's Cathedral is another must-see tourist attraction on your London sightseeing itinerary. Madame Tussauds, British Museum, Trafalgar Square and Piccadilly Circus are also places most visitors would go to. Markets and museums are both part of Londons cultural past, perhaps in different ways. London has many world class museums, among these are British Museum and Victoria & Albert Museum. A good way to see many of London's major sights are on the open-top double-decker tourist buses. There are different routes and many pick up points around London. The buses are "hop on and hop off" so when you get to landmarks you want to explore further you simply hop of the bus, and hop on to another once you have finished seeing what you wanted.
