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 generally extended to refer to the clock or the clock tower (officially known simply as Clock Tower) as well. The clock tower holds the largest four-faced chiming clock in the world and is the third-tallest free-standing clock tower. It celebrated its 150th anniversary on 31 May 2009, during which celebratory events took place. The tower was completed in 1858 and has become one of the most prominent symbols of both London and England, often in the establishing shot of films set in the city.

The present Clock Tower – metonymically referred to as Big Ben, and historically confused with St Stephen's Tower – was raised as a part of Charles Barry's design for a new palace, after the old Palace of Westminster was largely destroyed by fire on the night of 16 October 1834. The new Parliament was built in a Neo-gothic style. Although Barry was the chief architect of the Palace, he turned to Augustus Pugin for the design of the Clock Tower, which resembles earlier Pugin designs, including one for Scarisbrick Hall. The design for the Clock Tower was Pugin's last design before his final descent into madness and death, and Pugin himself wrote, at the time of Barry's last visit to him to collect the drawings: "I never worked so hard in my life for Mr Barry for tomorrow I render all the designs for finishing his bell tower & it is beautiful." The tower is designed in Pugin's celebrated Gothic Revival style, and is 316 feet (96.3 m) high (roughly 16 storeys).
