TranseptA transept (with two semitransepts) is a transverse part of any building, which lies across the main body of the building. In cruciform churches, a transept is an area set crosswise to the nave in a cruciform ("cross-shaped") building within the Romanesque and Gothic Christian church architectural traditions. Each half of a transept is known as a semitransept. The transept of a church separates the nave from the sanctuary, apse, choir, chevet, presbytery, or chancel.
Late antiquityLate antiquity was the time of transition from classical antiquity to the Middle Ages, generally spanning the 4th–8th century in Europe and adjacent areas bordering the Mediterranean Basin. The popularization of this periodization in English has generally been credited to historian Peter Brown, after the publication of his seminal work The World of Late Antiquity (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD.
DomeA dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a rotunda wall, a drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome.
Semi-domeIn architecture, a semi-dome (or half-dome) is a half dome that covers a semi-circular area in a building. Semi-domes are a common feature of apses in Ancient Roman and traditional church architecture, and in mosques and iwans in Islamic architecture. A semi-dome, or the whole apse, may also be called a conch after the scallop shell often carved as decoration of the semi-dome (all shells were conches in Ancient Greek), though this is usually used for subsidiary semi-domes, rather than the one over the main apse.
IstanbulIstanbul (ˌɪstænˈbʊl , USalsoˈɪstænbʊl ; İstanbul isˈtanbuɫ), formerly known as Constantinople (Κωνσταντινούπολις; Constantinopolis; Ottoman Turkish: قسطنطينيه), is the largest city in Turkey, serving as the country's economic, cultural and historic hub. The city straddles the Bosporus strait, lying in both Europe and Asia, and has a population of over 15 million residents, comprising 19% of the population of Turkey. Istanbul is the most populous European city and the world's 15th-largest city.
ApseIn architecture, an apse (plural apses; from Latin absis 'arch, vault' from Ancient Greek ἀψίς 'arch'; sometimes written apsis, plural apsides) is a semicircular recess covered with a hemispherical vault or semi-dome, also known as an exedra. In Byzantine, Romanesque, and Gothic Christian church (including cathedral and abbey) architecture, the term is applied to a semi-circular or polygonal termination of the main building at the liturgical east end (where the altar is), regardless of the shape of the roof, which may be flat, sloping, domed, or hemispherical.
BasilicaIn Ancient Roman architecture, a basilica was a large public building with multiple functions, typically built alongside the town's forum. The basilica was in the Latin West equivalent to a stoa in the Greek East. The building gave its name to the architectural form of the basilica. Originally, a basilica was an ancient Roman public building, where courts were held, as well as serving other official and public functions.
Hagia SophiaHagia Sophia ( 'Holy Wisdom'; Ayasofya; Hagía Sophía; Sancta Sapientia), officially the Hagia Sophia Mosque (Ayasofya-i Kebir Cami-i Şerifi), is a mosque and a major cultural and historical site in Istanbul, Turkey. The last of three church buildings to be successively erected on the site by the Eastern Roman Empire, it was completed in 537 AD. It was an Orthodox church until the Ottoman conquest of Constantinople in 1453, then a mosque until 1935, then a museum and then from 2020 a mosque again, as well as being a Roman Catholic cathedral for some decades after the Fourth Crusade of 1204.
Dome of the RockThe Dome of the Rock (Qubbat aṣ-Ṣakhra) is an Islamic shrine at the center of the Al-Aqsa mosque compound on the Temple Mount in the Old City of Jerusalem. Its initial construction was undertaken by the Umayyad Caliphate on the orders of Abd al-Malik during the Second Fitna in 691–692 CE, and it has since been situated on top of the site of the Second Jewish Temple (built in 516 BCE to replace the destroyed Solomon's Temple and rebuilt by Herod the Great), which was destroyed by the Romans in 70 CE.
BuildingA building or edifice is an enclosed structure with a roof and walls, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see Nonbuilding structure for contrast.
