Big Ben, Westminster Abbey and London Eye

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 usually extended to refer to both the clock and the clock tower as well. 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. When completed in 1859, it was, says clockmaker Ian Westworth, “the prince of timekeepers: the biggest, most accurate four-faced striking and chiming clock in the world.” The tower had its 150th anniversary on 31 May 2009, during which celebratory events took place. A British cultural icon, the tower is one of the most prominent symbols of the United Kingdom and is often in the establishing shot of films set in London. The Elizabeth Tower (previously called the Clock Tower), more popularly known as Big Ben, 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 in Lancashire. The design for the 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 315 feet (96.0 m) high.

Westminster Abbey, formally titled the Collegiate Church of St Peter at Westminster, is a large, mainly Gothic abbey church in the City of Westminster, London, just to the west of the Palace of Westminster. It is one of the United Kingdom's most notable religious buildings and the traditional place of coronation and burial site for English and, later, British monarchs. Between 1540 and 1556, the abbey had the status of a cathedral. Since 1560, however, the building is no longer an abbey nor a cathedral, having instead the status of a Church of England "Royal Peculiar"—a church responsible directly to the sovereign. The building itself is the original abbey church. According to a tradition first reported by Sulcard in about 1080, a church was founded at the site (then known as Thorn Ey (Thorn Island)) in the 7th century, at the time of Mellitus, a Bishop of London. Construction of the present church began in 1245, on the orders of King Henry III. Since the coronation of William the Conqueror in 1066, all coronations of English and British monarchs have been held in Westminster Abbey. There have been at least 16 royal weddings at the abbey since 1100. Two were of reigning monarchs (Henry I and Richard II), although, before 1919, there had been none for some 500 years.

The London Eye is a giant Ferris wheel on the South Bank of the River Thames in London. Also known as the Millennium Wheel, it has also been called by its owners the British Airways London Eye, the Merlin Entertainments London Eye, the EDF Energy London Eye and, as of mid-January 2015, the Coca-Cola London Eye. The structure is 443 feet (135 m) tall and the wheel has a diameter of 394 feet (120 m). When erected in 1999 it was the world's tallest Ferris wheel. Its height was surpassed by the 520 feet (158 m) tall Star of Nanchang in 2006, the 541 feet (165 m) tall Singapore Flyer in 2008, and the 550 feet (168 m) High Roller (Las Vegas) in 2014. Supported by an A-frame on one side only, unlike the taller Nanchang and Singapore wheels, the Eye is described by its operators as "the world's tallest cantilevered observation wheel". It is Europe's tallest Ferris wheel, and offered the highest public viewing point in London until it was superseded by the 804 feet (245 m) observation deck on the 72nd floor of The Shard, which opened to the public on 1 February 2013. It is the most popular paid tourist attraction in the United Kingdom with over 3.75 million visitors annually, and has made many appearances in popular culture.
