Big Ben is the nickname for the great bell of the clock at the north end of the Palace of Westminster in London, and is often extended to refer to the clock or the clock tower as well. Big Ben is the largest four-faced chiming clock and the third-tallest free-standing clock tower in the world. It celebrated its 150th anniversary in May 2009 (the clock itself first ticking on 31 May 1859), during which celebratory events took place.

Clock: The clock faces are large enough that the Clock Tower was once the largest four-faced clock in the world, but this has since been outdone by the Allen -Bradley Clock Tower in Milwaukee, Wisconsin. However, the builders of the Allen-Bradley Clock Tower did not add chimes to the clock, so the Great Clock of Westminster still holds the title of the "world's largest four-faced chiming clock". The clock and dials were designed by Augustus Pugin. The clock faces are set in an iron frame 7 metres (23 ft) in diameter, supporting 312 pieces of opal glass, rather like a stained-glass window. Some of the glass pieces may be removed for inspection of the hands. The surround of the dials is gilded. At the base of each clock face in gilt letters is the Latin inscription: " DOMINE SALVAM FAC REGINAM NOSTRAM VICTORIAM PRIMAM " Which means O Lord, keep safe our Queen Victoria the First.
