London highlights sightseeing full-day join-in tour from Harwich

Big Ben is the nickname for the Great Bell of the striking 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. 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 II. 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 stands 315 feet (96 m) tall, and the climb from ground level to the belfry is 334 steps. Its base is square, measuring 39 feet (12 m) on each side. Dials of the clock are 23 feet (7.0 m) in diameter.

Harwich is a town in Essex, England, and one of the Haven ports, located on the coast with the North Sea to the east. It is in the Tendring district. Nearby places include Felixstowe to the northeast, Ipswich to the northwest, Colchester to the southwest, and Clacton-on-Sea to the south. It is the northernmost coastal town within Essex. Its position on the estuaries of the Stour and Orwell rivers and its usefulness to mariners as the only safe anchorage between the Thames and the Humber led to a long period of maritime significance, both civil and military. The town became a naval base in 1657 and was heavily fortified, with Harwich Redoubt, Beacon Hill Battery, and Bath Side Battery. Harwich is the likely launch point of the Mayflower which carried English Puritans to North America and is the presumed birthplace of Mayflower Captain Christopher Jones. Harwich today is contiguous with Dovercourt and the two, along with Parkeston, are often referred to collectively as Harwich.
