Belfry (architecture) in the context of "Evesham Bell Tower"

A bell tower is a tower that contains one or more bells, or that is designed to hold bells even if it has none. Such a tower commonly serves as part of a Christian church, and will contain church bells, but there are also many secular bell towers, often part of a municipal building, an educational establishment, or a tower built specifically to house a carillon. Church bell towers often incorporate clocks, and secular towers usually do, as a public service.

The term campanile (/ˌkæmpəˈniːli, -leɪ/ KAM-pə-NEE-lee, -⁠lay, US also /ˌkɑːm-/ KAHM-, Italian: [kampaˈniːle]), from Italian and deriving from campana "bell", is synonymous with bell tower; though, in English usage, campanile tends to be used to refer to a free standing bell tower. A bell tower may also in some traditions be called a belfry, though this term may also refer specifically to the substructure that houses the bells and the ringers rather than the complete tower.

Big Ben is the nickname for the Great Bell of the Great Clock of Westminster, and, by extension, for the clock tower which stands at the north end of the Palace of Westminster in London, England. Originally named the Clock Tower, the structure was renamed the Elizabeth Tower in 2012 to mark the Diamond Jubilee of Queen Elizabeth II. The clock is a striking clock with five bells.

The tower was designed by Augustus Pugin and Sir Charles Barry in the Perpendicular Gothic style and was completed in 1859. It is decorated with stone carvings and features symbols related to the four countries of the United Kingdom and the Tudor dynasty. A Latin inscription celebrates Queen Victoria, under whose reign the palace was built. It stands 316 feet (96 m) tall, and the climb from ground level to the belfry is 334 steps. Its base is square, measuring 40 feet (12 m) on each side. The dials of the clock are 22.5 feet (6.9 m) in diameter.

The Giralda (Spanish: La Giralda [la xiˈɾalda]) is the bell tower of Seville Cathedral in Seville, Spain. It was built as the minaret for the Great Mosque of Seville in al-Andalus, during the reign of the Almohad dynasty, with a Renaissance-style belfry added by the Catholics after the expulsion of the Muslims from the area. The cathedral, including the Giralda, was registered in 1987 as a World Heritage Site by UNESCO, along with the Alcázar and the General Archive of the Indies. It remains one of the most important symbols of the city, as it has been since the Middle Ages. The tower is one of the most famous monuments of Moorish architecture in Spain and one of the most refined examples of Almohad architecture.

Douai (UK: /ˈduːeɪ/ DOO-ay, US: /duˈeɪ/ doo-AY, French: [dwɛ] ; Picard: Doï; Dutch: Dowaai; formerly spelled Douay or Doway in English) is a city in the Nord département in northern France. It is a sub-prefecture of the department. Located on the river Scarpe some 40 kilometres (25 miles) from Lille and 25 km (16 mi) from Arras, Douai is home to one of the region's most impressive belfries.

In architecture, a steeple is a tall tower on a building, topped by a spire and often incorporating a belfry and other components. Steeples are very common on Christian churches and cathedrals and the use of the term generally connotes a religious structure. They might be stand-alone structures, or incorporated into the entrance or center of the building.
