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.[3] The official name of the tower in which Big Ben is located was originally the Clock Tower, but it was renamed Elizabeth Tower in 2012 to mark the Diamond Jubilee of Elizabeth .

The tower was designed by Augustus Pugin in a neo-Gothic style. When completed in 1859, its clock was the largest and most accurate four-faced striking and chiming clock in the world.

The Tower of London, officially Her Majesty's Royal Palace and Fortress of the Tower of London, is a historic castle located on the north bank of the River Thames in central London. It lies within the London Borough of Tower Hamlets, which is separated from the eastern edge of the square mile of the City of London by the open space known as Tower Hill. It was founded towards the end of 1066 as part of the Norman Conquest of England. The White Tower, which gives the entire castle its name, was built by William the Conqueror in 1078

. Tower Bridge is in London: it crosses the River Thames near the Tower of London. It is a drawbridge, which allows ships through the bridge deck when the deck is raised in the center at an angle.

The London Eye is a large metal Ferris wheel. It is also known as the Millennium Wheel and is one of the largest observation wheels in the world. Since mid-January 2015 it has been known in branding as the Coca-Cola London Eye, after an agreement signed in September 2014.
