Cathedrals, collegiate churches, and monastic churches like those of abbeys and priories, often have certain complex structural forms that are found less often in parish churches. They also tend to display a higher level of contemporary architectural style and the work of accomplished craftsmen, and occupy a status both ecclesiastical and social that an ordinary parish church rarely has. Such churches are generally among the finest buildings locally and a source of regional pride. Many are among the world's most renowned works of architecture. These include St Peter's Basilica, Notre-Dame de Paris, Cologne Cathedral, Salisbury Cathedral, Antwerp Cathedral, Prague Cathedral, Lincoln Cathedral, the Basilica of Saint-Denis, Santa Maria Maggiore, the Basilica of San Vitale, St Mark's Basilica, Westminster Abbey, Saint Basil's Cathedral, Antoni Gaudí's incomplete Sagrada Família and the ancient cathedral of Hagia Sophia in Istanbul, now a mosque.
Donato Bramante, 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 the design executed by Michelangelo. His Tempietto 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.
Byzantine architecture is the architecture of the Byzantine Empire, or Eastern Roman Empire, usually dated from 330 AD, when Constantine the Great established a new Roman capital in Byzantium, which became Constantinople, until the fall of the Byzantine Empire in 1453. There was initially no hard line between the Byzantine and Roman Empires, and early Byzantine architecture is stylistically and structurally indistinguishable from late Roman architecture. The style continued to be based on arches, vaults and domes, often on a large scale. Wall mosaics with gold backgrounds became standard for the grandest buildings, with frescos a cheaper alternative.
In architecture, an apse is a semicircular recess covered with a hemispherical vault or semi-dome, also known as an exedra. In Byzantine, Romanesque, and Gothic Christian church architecture, the term is applied to a semi-circular or polygonal termination of the main building at the liturgical east end, regardless of the shape of the roof, which may be flat, sloping, domed, or hemispherical. Smaller apses are found elsewhere, especially in shrines.
A rotunda is any roofed building with a circular ground plan, and sometimes covered by a dome. It may also refer to a round room within a building. The Pantheon in Rome is perhaps the most famous, and is the most influential rotunda. A band rotunda is a circular bandstand, usually with a dome.
Jvari Monastery is a sixth-century Georgian Orthodox monastery near Mtskheta, eastern Georgia. Jvari is a rare case of an Early Medieval Georgian church that has survived to the present day almost unchanged. The church became the founder of its type, the Jvari type of church architecture, prevalent in Georgia and Armenia. Built atop of Jvari Mount, the monastery is an example of harmonious connection with the natural environment, characteristic to medieval Georgian architecture. Along with other historic structures of Mtskheta, the monastery was listed as a World Heritage Site by UNESCO in 1994.
Santa Costanza is a 4th-century church in Rome, Italy, on the Via Nomentana, which runs north-east out of the city. It is a round building with well preserved original layout and mosaics. It has been built adjacent to a horseshoe-shaped church, now in ruins, which has been identified as the initial 4th-century cemeterial basilica of Saint Agnes. Santa Costanza and the old Saint Agnes were both constructed over the earlier catacombs in which Saint Agnes is believed to be buried.
Saint Hripsime Church is a seventh century Armenian Apostolic church in the city of Vagharshapat (Etchmiadzin), Armenia. It is one of the oldest surviving churches in the country. The church was erected by Catholicos Komitas to replace the original mausoleum built by Catholicos Sahak the Great in 395 AD that contained the remains of the martyred Saint Hripsime to whom the church is dedicated. The current structure was completed in 618 AD. It is known for its fine Armenian-style architecture of the classical period, which has influenced many other Armenian churches since. It was listed as a UNESCO World Heritage Site along with other nearby churches, including Etchmiadzin Cathedral, Armenia's mother church, in 2000.
The Saint Gayane Church is a 7th-century Armenian church in Vagharshapat (Etchmiadzin), the religious center of Armenia. It is located within walking distance from the Etchmiadzin Cathedral of 301. St. Gayane was built by Catholicos Ezra I in the year 630. Its design has remained unchanged despite partial renovations of the dome and some ceilings in 1652.
The Ateni Sioni Church is an early 7th-century Georgian Orthodox church in the village of Ateni, some 10 km (6.2 mi) south of the city of Gori, Georgia. It stands in a setting of Ateni gorge in the Tana River valley known not only for its historical monuments, but also for its picturesque landscapes and wine. The name "Sioni" derives from Mount Zion at Jerusalem. Ateni is the tetraconch church, typical for the period. Its frescoes are one of the best examples of the Georgian painting.
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.

Ishkani or Ishkhan, is a ruined Christian monastery in the territory of Turkey in the village of İşhan, Artvin province. The name Ishkhani derives from the word “Իշխան” (Ishkhan) which means “prince” in the Armenian language. It was one of the important spiritual centers in the Middle Ages Tayk/Tao-Klarjeti. Only the magnificent church and the adjacent chapel have survived. The earliest mention of the monastery is found in The Life of Grigol Khandzteli, a Georgian manuscript dating from the year 951, which is now kept in Jerusalem.
Domes were a characteristic element of the architecture of Ancient Rome and of its medieval continuation, the Byzantine Empire. They had widespread influence on contemporary and later styles, from Russian and Ottoman architecture to the Italian Renaissance and modern revivals. The domes were customarily hemispherical, although octagonal and segmented shapes are also known, and they developed in form, use, and structure over the centuries. Early examples rested directly on the rotunda walls of round rooms and featured a central oculus for ventilation and light. Pendentives became common in the Byzantine period, provided support for domes over square spaces.
The early domes of the Middle Ages, particularly in those areas recently under Byzantine control, were an extension of earlier Roman architecture. The domed church architecture of Italy from the sixth to the eighth centuries followed that of the Byzantine provinces and, although this influence diminishes under Charlemagne, it continued on in Venice, Southern Italy, and Sicily. Charlemagne's Palatine Chapel is a notable exception, being influenced by Byzantine models from Ravenna and Constantinople. The Dome of the Rock, an Umayyad Muslim religious shrine built in Jerusalem, was designed similarly to nearby Byzantine martyria and Christian churches. Domes were also built as part of Muslim palaces, throne halls, pavilions, and baths, and blended elements of both Byzantine and Persian architecture, using both pendentives and squinches. The origin of the crossed-arch dome type is debated, but the earliest known example is from the tenth century at the Great Mosque of Córdoba. In Egypt, a "keel" shaped dome profile was characteristic of Fatimid architecture. The use of squinches became widespread in the Islamic world by the tenth and eleventh centuries. Bulbous domes were used to cover large buildings in Syria after the eleventh century, following an architectural revival there, and the present shape of the Dome of the Rock's dome likely dates from this time.
Samshvilde Sioni church is a ruined medieval Christian cathedral and one of the main architectural features of the historic site of Samshvilde in Georgia's southern region of Kvemo Kartli. A centralized domed building with apsed sanctuary and pastophoria, the church was built between 759 and 777. It is now in ruins and only fragments of the eastern wall remain standing. The church is inscribed on the list of the Immovable Cultural Monuments of National Significance of Georgia.
The Dzveli Gavazi church of the Mother of God is an early medieval Christian church in the eastern Georgian region of Kakheti. It is a tetraconch with the dome positioned over the centre of the square. Exactly when Dzveli Gavazi was built is not known. The church is dated on typological grounds to the 6th century, but it was reworked with the addition of an ambulatory at a later date, probably in the 9th century, and substantially repaired in 1852. The church is inscribed on the list of the Immovable Cultural Monuments of National Significance of Georgia.
