Tower in the context of Penthouse apartment

A church, church building, or chapel is a building used for Christian worship services and Christian activities. The earliest identified Christian church is a house church founded between 233 AD and 256 AD. The word church also describes a body or assembly of Christian believers, while "the Church" refers to the worldwide Christian religious community.

In traditional Christian architecture, the plan view of a church often forms a Christian cross. The center aisle and seating create the vertical beam, while the bema and altar form the horizontal arms. Towers or domes rise above the heaven-facing roof line to encourage contemplation of the divine. Modern churches employ varied architectural styles, and many buildings originally designed for other purposes have been converted to churches. From the 11th to the 14th centuries, Western Europe experienced a wave of church construction.

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.

A siege tower or breaching tower (or in the Middle Ages, a belfry) is a specialized siege engine, constructed to protect assailants and ladders while approaching the defensive walls of a fortification. The tower was often rectangular with four wheels with its height roughly equal to that of the wall or sometimes higher to allow archers or crossbowmen to stand on top of the tower and shoot arrows or quarrels into the fortification. While the towers were primarily constructed of wood and thus flammable, their builders typically incorporated whatever non-flammable coverings could be readily procured including iron and/or fresh animal skins.

Evidence for use of siege towers in Ancient Egypt and Anatolia dates to the Bronze Age. They were used extensively in warfare of the ancient Near East after the Late Bronze Age collapse, and in Egypt by Kushites from Sudan who founded the 25th dynasty. During classical antiquity they were common among Hellenistic Greek armies of the 4th century BC and later Roman armies of Europe and the Mediterranean, while also seeing use in ancient China during the Warring States Period and Han dynasty. Siege towers were of unwieldy dimensions and, like trebuchets, were therefore mostly constructed on site of the siege. Taking considerable time to construct, siege towers were mainly built if the defense of the opposing fortification could not be overcome by ladder assault ("escalade"), by mining, or by breaking walls or gates with tools such as battering rams.

A minaret is a type of tower typically built into or adjacent to mosques. Minarets are generally used to project the Muslim call to prayer (adhan) from a muezzin, but they also served as landmarks and symbols of Islam's presence. They can have a variety of forms, from thick, squat towers to soaring, pencil-thin spires.

A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world.

Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical suspender cables that transfer the live and dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework.

Italia turrita (pronounced [iˈtaːlja turˈriːta]; lit. 'Turreted Italy') is the national personification or allegory of Italy, in the appearance of a young woman with her head surrounded by a mural crown completed by towers (hence turrita or "with towers" in Italian). It is often accompanied by the Stella d'Italia ('Star of Italy'), which is the oldest national symbol of Italy, since it dates back to the Graeco-Roman tradition, from which the so-called Italia turrita e stellata ('turreted and starry Italy'), and by other additional attributes, the most common of which is the cornucopia. The allegorical representation with the towers, which draws its origins from ancient Rome, is typical of Italian civic heraldry, so much so that the mural crown is also the symbol of the cities of Italy.

Italia turrita, which is one of the national symbols of Italy, has been widely depicted for centuries in the fields of art, politics and literature. Its most classic aspect, which derives from the primordial myth of the Great Mediterranean Mother and which was definitively specified at the turn of the 16th and 17th centuries by Cesare Ripa, wants to symbolically convey the royalty and nobility of Italian cities (thanks to the presence of crown turrita), the abundance of agricultural crops of the Italian peninsula (represented by the cornucopia) and the shining destiny of Italy (symbolized by the Stella d'Italia).

In astronomy, axis mundi is the Latin term for the axis of Earth between the celestial poles. In a geocentric coordinate system, this is the axis of rotation of the celestial sphere. Consequently, in ancient Greco-Roman astronomy, the axis mundi is the axis of rotation of the planetary spheres within the classical geocentric model of the cosmos.

In 20th-century comparative mythology, the term axis mundi – also called the cosmic axis, world axis, world pillar, center of the world, or world tree – has been greatly extended to refer to any mythological concept representing "the connection between Heaven and Earth" or the "higher and lower realms". Mircea Eliade introduced the concept in the 1950s. Axis mundi closely relates to the mythological concept of the omphalos (navel) of the world or cosmos.Items presented as examples of the axis mundi by comparative mythologists include plants (notably a tree but also other types of plants such as a vine or stalk), a mountain, a column of smoke or fire, or a product of human manufacture (such as a staff, a tower, a ladder, a staircase, a maypole, a cross, a steeple, a rope, a totem pole, a pillar, a spire). Its proximity to heaven may carry implications that are chiefly religious (pagoda, Temple Mount, minaret, church) or secular (obelisk, lighthouse, rocket, skyscraper). The image appears in religious and secular contexts. The axis mundi symbol may be found in cultures utilizing shamanic practices or animist belief systems, in major world religions, and in technologically advanced "urban centers". In Mircea Eliade's opinion: "Every Microcosm, every inhabited region, has a Centre; that is to say, a place that is sacred above all."

A finial (from Latin finis 'end') or hip-knob is an element marking the top or end of some object, often formed to be a decorative feature.

In architecture, it is a small decorative device, employed to emphasize the apex of a dome, spire, tower, roof, or gable or any of various distinctive ornaments at the top, end, or corner of a building or structure. A finial is typically carved in stone. Where there are several such elements they may be called pinnacles. The very top of a finial can be a floral or foliated element called a bouquet.

A watchtower or guardtower (also spelt watch tower, guard tower) is a type of military/paramilitary or policiary tower used for guarding an area. Sometimes fortified, and armed with heavy weaponry, especially historically, the structures are built in areas of established control. These include military bases, cities occupied by military forces, prisons and more. A common equipment is searchlights.

It differs from a regular tower in that its primary use is military/policiary and from a turret in that it is usually a freestanding structure. Its main purpose is to provide a high, safe place from which a sentinel or guard may observe the surrounding area. In some cases, non-military towers, such as religious towers, may also be used as watchtowers.

This is a list of the tallest buildings. Tall buildings, such as skyscrapers, are intended here as enclosed structures with continuously occupiable floors and a height of at least 350 metres (1,150 ft). Such definition excludes non-building structures, such as towers.

A pagoda is a tiered tower with multiple eaves, common in Tibet, Thailand, Cambodia, Nepal, India, China, Japan, Korea, Myanmar, Vietnam, and other parts of Asia. Most pagodas were built to have a religious function, most often Buddhist, but sometimes Taoist or Hindu, and were often in or near viharas. The pagoda traces its origins to the stupa, while its design was developed in ancient India. Chinese pagodas (Chinese: 塔; pinyin: Tǎ) are a traditional part of Chinese architecture. In addition to religious use, since ancient times Chinese pagodas have been valued for the spectacular views they offer, and many classical poems attest to the joy of scaling pagodas.

The oldest and tallest pagodas were made of wood, but most that survived were made of brick or stone. Some are solid with no interior. Hollow pagodas have no higher floors or rooms, but the interior often contains an altar or a smaller pagoda, as well as a series of staircases for visitors to climb to see the view from an opening on one side of each tier. Most have between three and 13 tiers (almost always an odd number) and the classic gradual tiered eaves.

Tokyo Skytree (東京スカイツリー, Tōkyō Sukaitsurī; [toːkʲoː sɯ̥kaitsɯriː] ), also written as Tokyo Sky Tree, is a broadcasting and observation tower, located in Sumida, Tokyo, Japan. It has been the tallest tower in Japan since opening in 2012, and reached its full height of 634 m (2,080 ft) in early 2011, making it the tallest tower in the world, displacing the Canton Tower, and the third tallest structure in the world behind Merdeka 118 (678.9 m or 2,227 ft) and Burj Khalifa (829.8 m or 2,722 ft).

The tower is the primary television and radio broadcast site for the Kantō region; the older Tokyo Tower no longer gives complete digital terrestrial television broadcasting coverage because it is surrounded by high-rise buildings. Skytree was completed on Leap Day, 29 February 2012, with the tower opening to the public on 22 May 2012. The tower is the centerpiece of a large commercial development funded by Tobu Railway (which owns the complex) and a group of six terrestrial broadcasters headed by NHK. Trains stop at the adjacent Tokyo Skytree Station and nearby Oshiage Station. The complex is 7 km (4.3 mi) northeast of Tokyo Station. Sumida Aquarium is in the Tokyo Solamachi complex.

A transmission tower (also electricity pylon, hydro tower, or pylon) is a tall structure, usually a lattice or tubular tower made of steel, that is used to support an overhead power line. In electrical grids, transmission towers carry high-voltage transmission lines that transport bulk electric power from generating stations to electrical substations, from which electricity is delivered to end consumers; moreover, utility poles are used to support lower-voltage sub-transmission and distribution lines that transport electricity from substations to electricity customers.

There are four categories of transmission towers: (i) the suspension tower, (ii) the dead-end tower, (iii) the termination tower, and (iv) the transposition tower.The heights of transmission towers typically range from 15 to 55 m (49 to 180 ft), although when longer spans are needed, such as for crossing water, taller towers are sometimes used. More transmission towers are needed to mitigate climate change, and as a result, transmission towers became politically important in the 2020s.

A shot tower is a tower designed for the production of small-diameter shot balls by free fall of molten lead, which is then caught in a water basin. The shot is mainly used for projectiles in shotguns, and for ballast, radiation shielding, and other applications for which small lead balls are useful.

The fortifications of Kotor (Italian: Cattaro) are an integrated historical fortification system that protected the medieval town of Kotor containing ramparts, towers, citadels, gates, bastions, forts, cisterns, a castle, and ancillary buildings and structures. They incorporate military architecture of Illyria, the Byzantine Empire, Venice, and Austria. Together with the old town and its natural surroundings the fortifications were inscribed in the list of World Heritage Sites in 1979 labelled Natural and Culturo-Historical Region of Kotor and represent the only such site of cultural significance in Montenegro.

The fortified city of Kotor was also included in UNESCO's World Heritage Site list as part of Venetian Works of Defence between 15th and 17th centuries: Stato da Terra – western Stato da Mar in 2017.

The Laboe Naval Memorial (a.k.a. Laboe Tower, German: Marine-Ehrenmal Laboe) is a memorial located in Laboe, near Kiel, in Schleswig-Holstein, Germany. Started in 1927 and completed in 1936, the monument originally commemorated the World War I war dead of the Kaiserliche Marine, with the Kriegsmarine dead of World War II being added after 1945. In 1954 it was rededicated as a memorial for the sailors of all nationalities who were lost at sea and at the same time a memorial for peaceful sailing in open seas.

The monument consists of a 72-metre-high (236 ft) tower topped by an observation deck. The deck stands a total 85 m (279 ft) above sea level. A hall of remembrance and World War II-era German submarine U-995, which houses a technical museum, both sit near the foot of the monument, and the site is a popular tourist venue. U-995 is the world's only remaining Type VII U-boat.
