Spire in the context of NBC Tower

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.

This list of tallest church buildings ranks church buildings by height. From the Middle Ages until the advent of the skyscraper, Christian church buildings were often the world's tallest buildings. From 1311, when the spire of Lincoln Cathedral surpassed the height of the Great Pyramid of Giza, until the Washington Monument was completed in 1884, a succession of church buildings held this title.

• The tallest church building in the world is the Sagrada Família in Barcelona, which surpassed Ulm Minster (161.53 m) on 30 October 2025 when its central tower reached 162.91 m. The tower is intended to reach 172 m when completed, expected in 2026.
• The tallest church building in the world until 2025 was the Ulm Minster (161.53 m), the main Lutheran congregation in Ulm, Germany.
• The tallest domed church building, and the tallest Catholic church until surpassed by Sagrada Família, is the Basilica of Our Lady of Peace (158 m) in Yamoussoukro, Ivory Coast.
• The tallest cathedral as well as the tallest church building with two steeples is Cologne Cathedral (157.22 m) in Cologne, Germany.
• The tallest domed cathedral as well as the tallest Eastern Orthodox is People's Salvation Cathedral (132 m) in Bucharest, Romania.
• The tallest brickwork church building is St Martin's Church (130.6 m) in Landshut, Germany.
• The tallest brickwork church building with two steeples is St Mary's Church (125 m) in Lübeck, Germany.
• The tallest wooden church building is Săpânța-Peri Monastery church (78 m) in Săpânța, Romania.
• The tallest church building in the Americas is the Cathedral of Maringá (124 m) in Maringá, Brazil.

The cities with the most churches surpassing 99 metres (325 feet) are Hamburg (5 of the 29 tallest churches, with 5 towers overall), Lübeck (4 of the 56 tallest churches, two of which with twin towers → 6 towers overall), Vienna (2), Tallinn (2), St. Petersburg (2), New York City (2), Dortmund (2) and Stralsund (2).

One World Trade Center, also known as One WTC and as the Freedom Tower, is the main building of the rebuilt World Trade Center complex in Lower Manhattan, New York City. Designed by David Childs of Skidmore, Owings & Merrill, One World Trade Center is the tallest building in the United States, the tallest building in the Western Hemisphere, and the seventh-tallest in the world. The supertall structure has the same name as the North Tower of the original World Trade Center, which was destroyed in the terrorist attacks of September 11, 2001. The new skyscraper stands on the northwest corner of the 16-acre (6.5 ha) World Trade Center site, on the site of the original 6 World Trade Center. It is bounded by West Street to the west, Vesey Street to the north, Fulton Street to the south, and Washington Street to the east.

The construction of below-ground utility relocations, footings, and foundations for the new building began on April 27, 2006. One World Trade Center became the tallest structure in New York City on April 30, 2012, when it surpassed the height of the Empire State Building. The tower's steel structure was topped out on August 30, 2012. On May 10, 2013, the final component of the skyscraper's spire was installed, making the building, including its spire, reach a total height of 1,776 feet (541 m). Its height in feet is a deliberate reference to the year when the United States Declaration of Independence was signed. The building opened on November 3, 2014; the One World Observatory opened on May 29, 2015.

Salisbury Cathedral, formally the Cathedral Church of the Blessed Virgin Mary, is an Anglican cathedral in the city of Salisbury, England. The cathedral is regarded as one of the leading examples of Early English Gothic design. Built over a relatively short period, some 38 years between 1220 and 1258, it has a unity and coherence that is unusual in medieval English cathedrals. The tower and spire were completed by 1330. The cathedral's spire, at 404 feet (123 m), is the tallest in England.

The original cathedral in the district was located at Old Sarum, about 2 miles (3.2 km) north of the present city. In 1197 bishop Herbert Poore determined on a relocation but this was not taken forward until the episcopate of his brother, Richard Poore in the early 13th century. Foundation stones for the new building were laid on 28 April 1220 by the Earl and Countess of Salisbury. By 1258 the nave, transepts and choir were complete. The only major additions were the cloisters, added 1240, the chapter house in 1263, and the tower and spire, which was constructed by 1330. At its completion it was the third highest in England, but the collapse of those at Lincoln Cathedral and Old St Paul's Cathedral in the 16th century saw Salisbury become England's tallest.

Strasbourg Cathedral or the Cathedral of Our Lady of Strasbourg (French: Cathédrale Notre-Dame de Strasbourg, or Cathédrale de Strasbourg, German: Liebfrauenmünster zu Straßburg), also known as Strasbourg Minster (German: Straßburger Münster), is a Catholic cathedral in Strasbourg, Alsace, France. Although considerable parts of it are still in Romanesque architecture, it is widely considered to be among the finest examples of Rayonnant Gothic architecture. Architect Erwin von Steinbach is credited for major contributions from 1277 to his death in 1318, and beyond through his son Johannes von Steinbach, and his grandson Gerlach von Steinbach, who succeeded him as chief architects. The Steinbachs' plans for the completion of the cathedral were not followed through by the chief architects who took over after them, and instead of the originally envisioned two spires, a single, octagonal tower with an elongated, octagonal crowning was built on the northern side of the west facade by master Ulrich Ensingen and his successor, Johannes Hültz. The construction of the cathedral, which had started in the year 1015 and had been relaunched in 1190, was finished in 1439.

Standing in the centre of the Place de la Cathédrale, at 142 metres (466 feet), Strasbourg Cathedral was the world's tallest building from 1647 to 1874 (227 years), when it was surpassed by St. Nikolai's Church, Hamburg. Today it is the sixth-tallest church in the world and the tallest extant structure built entirely in the Middle Ages.

Saint Fin Barre's Cathedral (Irish: Ardeaglais Naomh Fionnbarra) is a Gothic Revival three-spire Church of Ireland cathedral in Cork city, Ireland. It is located on the south bank of the River Lee and dedicated to Finbarr of Cork, patron saint of the city. Formerly the sole cathedral of the Diocese of Cork, it is now one of three co-cathedrals in the United Dioceses of Cork, Cloyne and Ross in the ecclesiastical province of Dublin. Christian use of the site dates back 7th-century AD when, according to local lore, Finbarr of Cork founded a monastery. The original building survived until the 12th century, when it either fell into disuse or was destroyed during the Norman invasion of Ireland. Around 1536, during the Protestant Reformation, the cathedral became part of the established church, later known as the Church of Ireland. The previous building was constructed in the 1730s, but was widely regarded as plain and featureless.

The cathedral's demolition and rebuild was commissioned in the mid-19th century by an Anglican church intent on strengthening its hand after the reforms of penal law. Work began in 1863, and resulted in the first major commissioned project for the Victorian architect William Burges, who designed most of the cathedral's architecture, sculpture, stained glass, mosaics and interior furniture. Saint Fin Barre's foundation stone was laid in 1865. The cathedral was consecrated in 1870 and the limestone spires completed by October 1879.

The DC Towers, also known as the Donau City Towers, is a mixed-use skyscraper complex in the Donaustadt District of Vienna, Austria. The towers were designed by French architect Dominique Perrault. Werner Sobek AG was responsible for the structural engineering as well as the facade and height access planning of DC Tower 1.

DC Tower 1, the tallest skyscraper in Austria at 220 metres (720 ft) or 250 metres (820 ft) including the antenna spire, was officially finished with an opening ceremony on 26 February 2014 attended by architect Perrault and former astronaut Buzz Aldrin. Due to the 2008 financial crisis, ground breaking was delayed several times. Eventually, construction was started on 17 June 2010.

The Spire of Notre-Dame de Paris is located above the cross-section of the cathedral's transept. Notre-Dame de Paris has had three timber spires made of oak, known as flèches. The first was built between 1220 and 1230. It eventually became so damaged that it was removed in the late 18th century. The second was put into place by the French architect Eugène Viollet-le-Duc in 1859, and destroyed in a major fire on 15 April 2019. Work to construct a third one started in 2022, and was completed when the new copper rooster wind vane was placed on top of the new spire on 16 December 2023, and the third spire was unveiled on 13 February 2024.

A flèche (French: [flɛʃ] ; French for 'arrow') is the name given to spires in Gothic architecture. In French, the word is applied to any spire, but in English it has the technical meaning of a spirelet or spike on the rooftop of a building. In particular, the spirelets often were built atop the crossings of major churches in mediaeval French Gothic architecture are called flèches.

On the ridge of the roof on top of the crossing (the intersection of the nave and the transepts) of a church, flèches were typically light, delicate, timber-framed constructions with a metallic sheath of lead or copper. They are often richly decorated with architectural and sculptural embellishments: tracery, crockets, and miniature buttresses serve to adorn the flèche.

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.

A pinnacle is an architectural element originally forming the cap or crown of a buttress or small turret, but afterwards used on parapets at the corners of towers and in many other situations. The pinnacle looks like a small spire. It was mainly used in Gothic architecture.

Børsen (Danish for "the bourse" or "the stock exchange"), is a 17th-century commodity bourse and later stock exchange in the centre of Copenhagen, Denmark. The historic building is situated next to Christiansborg Palace, the seat of the Danish Parliament, on the island of Slotsholmen.

Built under the reign of Christian IV in 1619–1640, the building is considered a leading example of the Dutch Renaissance style in Denmark. It is a protected building for conservation purposes. A popular tourist attraction, Børsen is most noted for its distinctive spire, shaped as the tails of four dragons twined together, reaching a height of 56 m (184 ft). On 16 April 2024, the building was severely damaged by a fire, which toppled the spire.

Paul's Cross (alternatively "Powles Crosse") was a preaching cross and open-air pulpit in St Paul's Churchyard, the grounds of Old St Paul's Cathedral, City of London. It was the most important public pulpit in Tudor and early Stuart England, and many of the most important statements on the political and religious changes brought by the Reformation were made public from here. The pulpit stood in 'the Cross yard', the open space on the north-east side of St Paul's Churchyard, adjacent to the row of buildings that would become the home of London's publishing and book-selling trade.

A monumental memorial column called "Paul's Cross" with a golden statue of St Paul stands in this area of the Cathedral precinct since the early 20th century, but it is not on the exact spot where Paul's Cross stood. A stone carved with the words 'Here stood Paul's Cross' marks the actual location of the pulpit as it stood from 1449 until 1635, when it was taken down during Inigo Jones' renovation work.

The architecture of metropolitan Detroit continues to attract the attention of architects and preservationists alike. With one of the world's recognizable skylines, Detroit's waterfront panorama shows a variety of architectural styles. The post-modern neogothic spires of One Detroit Center refer to designs of the city's historic Art Deco skyscrapers. Together with the Renaissance Center, they form the city's distinctive skyline.

Detroit's architecture is recognized as being among the finest in the U.S. Detroit has one of the largest surviving collections of late-19th- and early-20th-century buildings in the U.S. Because of the city's economic difficulties, the National Trust for Historic Preservation has listed many of Detroit's skyscrapers and buildings as some of America's most endangered landmarks.

St Mark's Campanile (Italian: Campanile di San Marco, Venetian: Canpanièl de San Marco) is the bell tower of St Mark's Basilica in Venice, Italy. The campanile is a reconstruction completed in 1912, the previous tower having collapsed in 1902. At 98.6 metres (323 ft) in height, it is the tallest structure in Venice and is colloquially termed "el paròn de casa" (the master of the house). It is one of the most recognizable symbols of the city.

Located in Saint Mark's Square near the mouth of the Grand Canal, the campanile was initially intended as a watchtower to sight approaching ships and protect the entry to the city. It also served as a landmark to guide Venetian ships safely into harbour. Construction began in the early tenth century and continued sporadically over time as the tower was slowly raised in height. A belfry and a spire were first added in the twelfth century. In the fourteenth century the spire was gilded, making the tower visible to distant ships in the Adriatic. The campanile reached its full height in 1514 when the belfry and spire were completely rebuilt on the basis of an earlier Renaissance design by Giorgio Spavento. Historically, the bells served to regulate the civic and religious life of Venice, marking the beginning, pauses, and end of the work day; the convocation of government assemblies; and public executions.

The Collegiate Church of St. Peter and St. Guido (French: Collégiale Saints-Pierre-et-Guidon; Dutch: Sint-Pieter-en-Sint-Guidokerk) is a Catholic collegiate church in the historical centre of Anderlecht, a municipality of Brussels, Belgium. It is dedicated to Saint Peter and Saint Guy, the patron saint of Anderlecht.

The church, in Brabantine Gothic style, was built between the 14th and 16th centuries above an earlier Romanesque crypt. Partially attributed to the Flemish architect Jan van Ruysbroeck, it is a notable illustration of late medieval architecture in Brussels. Its neo-Gothic spire dates from the 19th century. The complex was designated a historic monument in 1938.
