London Bridge is a bridge between the City of London and Southwark in London, England, over the River Thames. Situated between Cannon Street Railway Bridge and Tower Bridge, it forms the western end of the Pool of London. On the south side of the bridge are Southwark Cathedral and London Bridge station; on the north side are the Monument to the Great Fire of London and Monument tube station.
Big Ben is the nickname for the great bell of the clock at the north-eastern end of the Palace of Westminster in London. The nickname is often also used to refer to the clock and the clock tower. This is the world's largest four-faced, chiming clock and the third largest free-standing clock tower in the world. It celebrates its 150th birthday in 2009, during which celebratory events are planned.
