Big Ben is the nickname for the Great Bell of the clock at the north end of the Palace of Westminster in London, and often extended to refer to the clock and the clock tower. The tower is officially known as Elizabeth Tower, renamed to celebrate the Diamond Jubilee of Elizabeth II in 2012; previously it was known simply as the Clock Tower. The tower holds the second largest four-faced chiming clock in the world. The tower was completed in 1859 and had its 150th anniversary on 31 May 2009, during which celebratory events took place. The tower has become one of the most prominent symbols of the United Kingdom and is often in the establishing shot of films set in London.

Many historical bridges named London Bridge have spanned the River Thames between the City of London and Southwark, in central London. The current crossing, which opened to traffic in 1974, is a box girder bridge built from concrete and steel. This replaced a 19th-century stone-arched bridge, which in turn superseded a 600-year-old medieval structure. This was preceded by a succession of timber bridges, the first built by the Roman founders of London.
