Seville Cathedral in the context of "Roof lantern"

Hagia Sophia, officially the Hagia Sophia Grand Mosque, is a mosque serving as a major cultural and historical site in Istanbul, Turkey. It was formerly a church (360–1453) and a museum (1935–2020). The last of three church buildings to be successively erected on the site by the Eastern Roman Empire, it was completed in AD 537, becoming the world's largest interior space and among the first to employ a fully pendentive dome. It is considered the epitome of Byzantine architecture and is said to have "changed the history of architecture". From its dedication in 360 until 1453 Hagia Sophia served as the cathedral of Constantinople in the Byzantine liturgical tradition, except for the period 1204–1261 when the Latin Crusaders installed their own hierarchy. After the fall of Constantinople in 1453, it served as a mosque, having its minarets added soon after. The site became a museum in 1935, and was redesignated as a mosque in 2020.

The current structure was built by the Byzantine emperor Justinian I as the Christian cathedral of Constantinople between 532–537 and was designed by the Greek geometers Isidore of Miletus and Anthemius of Tralles. It was formally called the Temple of God's Holy Wisdom, (Greek: Ναὸς τῆς Ἁγίας τοῦ Θεοῦ Σοφίας, romanized: Naòs tês Hagías toû Theoû Sophías) the third church of the same name to occupy the site, as the prior one had been destroyed in the Nika riots. As the episcopal see of the ecumenical patriarch of Constantinople, it remained the world's largest cathedral for nearly a thousand years, until the Seville Cathedral was completed in 1520.

Seville (/səˈvɪl/ sə-VIL; Spanish: Sevilla, pronounced [seˈβiʎa] ) is the capital and largest city of the Spanish autonomous community of Andalusia and the province of Seville. It is situated on the lower reaches of the River Guadalquivir, in the southwest of the Iberian Peninsula.

Seville has a municipal population of about 686,741 as of 2024, and a metropolitan population of about 1.5 million, making it the largest city in Andalusia and the 5th-largest city in Spain. Its old town, with an area of 4 square kilometres (2 sq mi), contains a UNESCO World Heritage Site comprising three buildings: the Alcázar palace complex, the Cathedral and the General Archive of the Indies. The Port of Seville, located about 80 kilometres (50 miles) from the Atlantic Ocean, is the only river harbour in Spain. The capital of Andalusia enjoys hot temperatures in the summer, with daily maximums routinely above 35 °C (95 °F) in July and August.

Havana Cathedral (Catedral de la Purísima Concepción de María) is one of eleven Catholic cathedrals on the island. It is located in the Plaza de la Catedral on Calle Empedrado, between San Ignacio y Mercaderes, Old Havana, Havana, Cuba. The thirty by forty-nine meters rectangular church serves as the seat of the Archdiocese of San Cristóbal de la Habana. Christopher Columbus’s remains were kept in the cathedral between 1796 and 1898 before they were taken to Seville Cathedral.

It was built between 1748 and 1777 and was consecrated in 1782.

The Alcázar of Seville, officially called Royal Alcázar of Seville (Spanish: Real Alcázar de Sevilla or Reales Alcázares de Sevilla), is a historic royal palace in Seville, Spain and one of the official residences of the Spanish royal family. It was formerly the site of the Islamic-era citadel of the city, begun in the 10th century under the Umayyads and then developed into a larger palace complex by the Abbadid dynasty (11th century) and the Almohads (12th to early 13th centuries). After the Castilian conquest of the city in 1248, the site was progressively rebuilt and replaced by new palaces and gardens. Among the most important of these is a richly decorated Mudéjar-style palace built by Pedro I during the 1360s.

The palace is a preeminent example of Mudéjar style in the Iberian Peninsula and also includes sections with Gothic and Renaissance elements. The upper storeys of the Alcázar are still occupied by the royal family when they visit Seville and are administered by the Patrimonio Nacional. It was registered in 1987 by UNESCO as a World Heritage Site, along with the adjoining Seville Cathedral and the General Archive of the Indies.

The Archivo General de Indias (Spanish pronunciation: [aɾˈtʃiβo xeneˈɾal de ˈindjas]; standard abbreviation AGI; lit. 'General Archive of the Indies'), often simply called the Archive of the Indies, was created by Charles III and inaugurated in 1785. It is housed in the former merchant guild building in Seville, Spain, built in the late 16th century. It became the repository of archival materials documenting the history of the Spanish Empire in the Americas and Asia. The building was designed by Juan de Herrera; it is an Italianate example of Spanish Renaissance architecture. This structure and its contents were registered in 1987 by UNESCO as a World Heritage Site, together with the adjoining Seville Cathedral and the Alcázar of Seville.

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.

The Archbishop's Palace of Seville (Palacio Arzobispal) is a palace in Seville, Spain. It has served as the residence of bishops and archbishops of the episcopal sees and numerous nobleman and military figures to the present time. It is located in the southern section of Seville, in the Plaza Virgen de los Reyes, angled almost opposite the Giralda. It is situated on the northeastern side of Seville Cathedral in the neighborhood of Santa Cruz. Of Spanish Baroque architectural style, it has had the status of National Monument since 1969.
