From the Golden Jubilee Bridge you look south over the Thames and see the big Ferris wheel London Eye up to Big Ben heaviest of the five bells that play the famous Westminster chime. The clock tower is part of the Palace of Westminster, a monumental, neo-Gothic building that houses the British Parliament, consisting of the House of Commons and the House of Lords. The palace is located in the City of Westminster on Parliament Square, very close to Whitehall. It was declared a World Heritage Site by UNESCO in 1987.
