Triconch
A tetraconch, from the Greek for "four shells", is a building, usually a church or other religious building, with four apses, one in each direction, usually of equal size. The basic ground plan of the building is therefore a Greek cross. They are most common in Byzantine, and related schools such as Armenian and Georgian architecture. It has been argued that they were developed in these areas or Syria, and the issue is a matter of contention between the two nations in the Caucasus. Apart from churches, the form is suitable for a mausoleum or baptistery. Normally, there will be a higher central dome over the central space. Overview The Basilica of San Lorenzo, Milan (370) is possibly the first example of a grander type, the "aisled tetraconch", with an outer ambulatory. In middle Byzantine architecture, the cross-in-square plan was developed, essentially filling out the tetraconch to form a square-ish exterior. Either of these types may also be described less precisely as "cros ...

Cross-in-square
A cross-in-square or crossed-dome plan was the dominant architectural form of middle- and late-period Byzantine churches. It featured a square centre with an internal structure shaped like a cross, topped by a dome. The first cross-in-square churches were probably built in the late 8th century, and the form has remained in use throughout the Orthodox world unto the present day. In the West, Donato Bramante's first design (1506) for St. Peter's Basilica was a centrally planned cross-in-square under a dome and four subsidiary domes. In German, such a church is a , or ‘cross-dome church’. In French, it is an , ‘church with an inscribed cross’. Architecture Architectural form A cross-in-square church is centered around a quadratic naos (the ‘square’) which is divided by four columns or piers into nine bays (divisions of space). The inner five divisions form the shape of a quincunx (the ‘cross’). The central bay is usually larger than the other eight, and is ...

Semi-dome
In architecture, a semi-dome (or half-dome) is a half dome that covers a semi-circular area in a building. Architecture 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. Small semi-domes have been often decorated in a shell shape from ancient times, as in Piero della Francesca's ''Throned Madonna with saints and Federigo da Montefeltro'', and the example in the gallery below. Islamic examples may use muqarnas decorative corbelling, while in Late Antique, Byzantine and medieval church architecture the semi-dome is the classic location for a focal mosaic, or later fresco. Found in many Ancient Greek exedras, the semi-dome ...

Church Architecture
Church architecture refers to the architecture of buildings of churches, convents, seminaries etc. It has evolved over the two thousand years of the Christian religion, partly by innovation and partly by borrowing other architectural styles as well as responding to changing beliefs, practices and local traditions. From the birth of Christianity to the present, the most significant objects of transformation for Christian architecture and design were the great churches of Byzantium, the Romanesque abbey churches, Gothic cathedrals and Renaissance basilicas with its emphasis on harmony. These large, often ornate and architecturally prestigious buildings were dominant features of the towns and countryside in which they stood. However, far more numerous were the parish churches in Christendom, the focus of Christian devotion in every town and village. While a few are counted as sublime works of architecture to equal the great cathedrals and churches, the majority developed along ...

Ravenna
Ravenna ( , , also ; rgn, Ravèna) is the capital city of the Province of Ravenna, in the Emilia-Romagna region of Northern Italy. It was the capital city of the Western Roman Empire from 408 until its collapse in 476. It then served as the capital of the Ostrogothic Kingdom until it was re-conquered in 540 by the Byzantine Empire. Afterwards, the city formed the centre of the Byzantine Exarchate of Ravenna until the last exarch was executed by the Lombards in 751. Although it is an inland city, Ravenna is connected to the Adriatic Sea by the Candiano Canal. It is known for its well-preserved late Roman and Byzantine architecture, with eight buildings comprising the UNESCO World Heritage Site "Early Christian Monuments of Ravenna". History The origin of the name ''Ravenna'' is unclear. Some have speculated that "Ravenna" is related to "Rasenna" (or "Rasna"), the term that the Etruscans used for themselves, but there is no agreement on this point. Ancient era The origins of ...

Zvartnots Cathedral
Zvartnots Cathedral ( hy, Զուարթնոց ( classical); ( reformed), sometimes rendered in scholarly works as Zuart'nots' or Zuart'noc' ; literally 'celestial angels cathedral') is a medieval Armenian cathedral near Vagharshapat (Ejmiatsin), Armenia. Built in the seventh century and now lying in ruins, Zvartnots was noted for its circular exterior structure, unique in medieval Armenian architecture, and a set of interior piers that upheld a multifloor structure crowned with a dome. History Zvartnots was built during the first Muslim Arab raids to capture and conquer the territories of Byzantine and Sasanian Armenia. Construction of the cathedral began in 643, under the guidance of Catholicos Nerses III the Builder (''Shinogh''). Dedicated to St. Gregory, the cathedral was built on a location where a meeting between King Trdat III and Gregory the Illuminator was said to have taken place. According to the medieval Armenian historian Movses Kaghankatvatsi, the cathedra ...

Mausoleum Of Galla Placidia
The Mausoleum of Galla Placidia is a Late Antique Roman building in Ravenna, Italy, built between 425 and 450. It was added to the World Heritage List together with seven other structures in Ravenna in 1996. Despite its common name, the empress Galla Placidia (d. 450) was not buried in the building, a misconception dating from the thirteenth century; she died in Rome and was buried there, probably alongside Honorius in the Mausoleum of Honorius at Old Saint Peter's Basilica. History The "mausoleum" of Galla Placidia, built 425–450, is a cruciform chapel or oratory that originally adjoined the narthex of the Church of the Holy Cross (''Santa Croce'') in Ravenna. It was probably dedicated to Saint Lawrence. Aelia Galla Placidia, the likely patron of the building's construction, was the daughter of Theodosius I and Galla, the daughter of Valentinian I. Raised by Serena, wife of Stilicho, she was made '' nobilissima'' in her youth and granted a palace by her father in Co ...

Bramante
Donato Bramante ( , , ; 1444 – 11 April 1514), born as Donato di Pascuccio d'Antonio and also known as Bramante Lazzari, was an Italian architect and painter. He introduced Renaissance architecture to Milan and the High Renaissance style to Rome, where his plan for St. Peter's Basilica formed the basis of design executed by Michelangelo. His Tempietto ( San Pietro in Montorio) marked the beginning of the High Renaissance in Rome (1502) when Pope Julius II appointed him to build a sanctuary over the spot where Peter was martyred. Life Urbino Bramante was born under the name Donato d'Augnolo, Donato di Pascuccio d'Antonio, or Donato Pascuccio d'Antonio in Fermignano near Urbino. Here, in 1467, Luciano Laurana was adding to the Palazzo Ducale an arcaded courtyard and other Renaissance features to Federico da Montefeltro's ducal palace. Bramante's architecture has eclipsed his painting skills: he knew the painters Melozzo da Forlì and Piero della Francesca well, who ...

Mosaic
A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman Kingdom of Sicily in the 12th century, by the eastern-influenced Republic of Venice, and among the Rus. Mosaic fell ...

Ambulatory
The ambulatory ( la, ambulatorium, ‘walking place’) is the covered passage around a cloister or the processional way around the east end of a cathedral or large church and behind the high altar. The first ambulatory was in France in the 11th century but by the 13th century ambulatories had been introduced in England and many English cathedrals were extended to provide an ambulatory. The same feature is often found in Indian architecture and Buddhist architecture generally, especially in older periods. Ritual circumambulation or parikrama around a stupa or cult image is important in Buddhism and Hinduism. Often the whole building was circumambulated, often many times. The Buddhist chaitya hall always allowed a path for this, and the Durga temple, Aihole (7th or 8th century) is a famous Hindu example. The term is also used to describe a garden feature in the grounds of a country house. A typical example is the one shown, which stands in the grounds of Horton Court in Glouces ...

Basilica Of St
In Ancient Roman architecture, a basilica is 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. Basilicas are typically rectangular buildings with a central nave flanked by two or more longitudinal aisles, with the roof at two levels, being higher in the centre over the nave to admit a clerestory and lower over the side-aisles. An apse at one end, or less frequently at both ends or on the side, usually contained the raised tribunal occupied by the Roman magistrates. The basilica was centrally located in every Roman town, usually adjacent to the forum and often opposite a temple in imperial-era forums. Basilicas were also built in private residences ...
