Clock tower in the context of Towers

The San Francisco Ferry Building is a terminal for ferries that travel across the San Francisco Bay, a food hall and an office building. It is located on The Embarcadero in San Francisco, California and is served by Golden Gate Ferry and San Francisco Bay Ferry routes.

On top of the building is a 245-foot-tall (75 m) clock tower with four clock dials, each 22 feet (6.7 m) in diameter, which can be seen from Market Street, a main thoroughfare of the city.

A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures.

Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building.

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.

Su Song (Chinese: 蘇頌; Pe̍h-ōe-jī: So͘ Siōng, 1020–1101), courtesy name Zirong (Chinese: 子容; Pe̍h-ōe-jī: Chú-iông), was a Chinese polymathic scientist and statesman who lived during the Song dynasty (960–1279). He excelled in numerous fields including but not limited to mathematics, astronomy, cartography, geography, metallurgy, mechanical engineering, hydraulic engineering, poetry, and statesmanship.

Su Song was the engineer for a hydro-mechanical astronomical clock tower located in Kaifeng. It employed an early escapement mechanism. The escapement mechanism of Su's clock tower was invented by the Tang dynasty Buddhist monk Yi Xing and government official Liang Lingzan in 725 AD to operate a water-powered armillary sphere, however Su's armillary sphere was the first to utilize a mechanical clock drive. Su's clock tower also featured the oldest known endless power-transmitting chain drive, called the tian ti (天梯), or "celestial ladder", as depicted in his horological treatise. The clock tower had 133 different clock jacks to indicate and sound the hours. The clock was dismantled by the invading Jurchen army in 1127 AD, and although attempts were made to reassemble it, the tower was never successfully reinstated.

A turret clock or tower clock is a clock designed to be mounted high in the wall of a building, usually in a clock tower, in public buildings such as churches, university buildings, and town halls. As a public amenity to enable the community to tell the time, it has a large face visible from far away, and often a striking mechanism which rings bells upon the hours.

The turret clock is one of the earliest types of clock. Beginning in 12th century Europe, towns and monasteries built clocks in high towers to strike bells to call the community to prayer. Public clocks played an important timekeeping role in daily life until the 20th century, when accurate watches became cheap enough for ordinary people to afford. Today the time-disseminating functions of turret clocks are not much needed, and they are mainly built and preserved for traditional, decorative, and artistic reasons.

The Zytglogge (Bernese German: [ˈtsiˌkːlɔkːə]; lit. 'time bell') is a landmark medieval tower in Bern, Switzerland. Built in the early 13th century, it has served the city as a guard tower, prison, clock tower, centre of urban life and civic memorial.

Despite the many redecorations and renovations it has undergone in its 800 years of existence, the Zytglogge is one of Bern's most recognisable symbols and the oldest monument of the city, and with its 15th-century astronomical clock, a major tourist attraction. It is a heritage site of national significance, and part of the Old City of Bern, a UNESCO World Heritage Site.

The Al-Askari Shrine (Arabic: مَرْقَد ٱلْإِمَامَيْن عَلِيّ ٱلْهَادِي وَٱلْحَسَن ٱلْعَسْكَرِيّ, romanized: Marqad al-ʾImāmayn ʿAlī al-Hādī wal-Ḥasan al-ʿAskarī, lit. 'Resting Place of the Two Imams Ali al-Hadi and Hasan al-Askari'), also known as the 'Askariyya Shrine and the Al-Askari Mosque, is a Twelver Shi'ite mosque and mausoleum, located in the city of Samarra, in the Saladin Governorate of Iraq.

Built in 944 CE, it is one of the most important Shia shrines in the world. The dome was destroyed in a bombing by Sunni extremists in February 2006 and its two remaining minarets were destroyed in another bombing in June 2007, causing widespread anger among Shias and instigation of the Iraqi Civil War between the country's Shia and Sunni factions. The remaining clock tower was also destroyed in July 2007. The dome and minarets were repaired and the mosque reopened in April 2009.

The Tower of the Winds, known as the Ωρολόγιο του Κυρρήστου in Greek, and by other names, is an octagonal Pentelic marble tower in the Roman Agora in Athens, named after the eight large reliefs of wind gods (in the form of young winged men and old men) around its top. Its date is uncertain, but was completed by about 50 BC, at the latest, as it was mentioned by Varro in his De re Rustica of about 37 BC. It is "one of the very small number of buildings from classical antiquity that still stands virtually intact", as it has been continuously occupied for a series of different functions.

Formerly topped by a wind vane, it is the only surviving horologium or clock tower from classical antiquity. It also housed a large water clock and incorporated sundials placed prominently on its exterior faces; "citizens were thus able by using this building to orient themselves in space and time. Architecture, sculpture and the new science were perfectly integrated".

The Beurs van Berlage (literally Berlage's stock market) is a building on the Damrak, in the centre of Amsterdam. It was designed by architect Hendrik Petrus Berlage and constructed between 1896 and 1903. It influenced many modernist architects, in particular functionalists and the Amsterdam School. It is now used as a venue for concerts, exhibitions and conferences.

The building is constructed of red brick, with an iron and glass roof, and stone piers, lintels and corbels. Its entrance is under a 40-metre (130 ft) high clock tower, while inside lie three large multi-storey halls, with offices and communal facilities grouped around them.

London Road Campus of the University of Reading is the original campus of that university. It is on the London Road, immediately to the south of Reading town centre in the English county of Berkshire.

The site for the campus was given to the university in 1904 by the Palmer family, owners of Reading's Huntley & Palmers biscuit makers. It served as the university's main site until after the much larger Whiteknights Campus was acquired in 1947.
