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.
The richest interiors were finished with thin plates of marble or coloured and patterned stone. Some of the columns were also made of marble. Other widely used materials were bricks and stone. [1] Mosaics made of stone or glass tesserae were also elements of interior architecture. Precious wood furniture, like beds, chairs, stools, tables, bookshelves and silver or golden cups with beautiful reliefs, decorated Byzantine interiors. [2]
Early Byzantine architecture drew upon earlier elements of Roman and Greek architecture. Stylistic drift, technological advancement, and political and territorial changes meant that a distinct style gradually resulted in the Greek cross plan in church architecture. [3] Civil architecture continued Greco-Roman trends; the Byzantines built impressive fortifications and bridges, but generally not aqueducts on the same scales as the Romans.
This terminology was introduced by modern historians to designate the medieval Roman Empire as it evolved as a distinct artistic and cultural entity centered on the new capital of Constantinople (modern-day Istanbul) rather than the city of Rome and its environs. Its architecture dramatically influenced the later medieval architecture throughout Europe and the Near East.
When the Roman Empire became Christian (after having extended eastwards) with its new capital at Constantinople, its architecture became more sensuous and ambitious. This new style with exotic domes and richer mosaics would come to be known as "Byzantine" before it traveled west to Ravenna and Venice and as far north as Moscow. Most of the churches and basilicas have high-riding domes, which created vast open spaces at the centers of churches, thereby heightening the light. The round arch is a fundamental of Byzantine style. Magnificent golden mosaics with their graphic simplicity brought light and warmth into the heart of churches. Byzantine capitals break away from the Classical conventions of ancient Greece and Rome with sinuous lines and naturalistic forms, which are precursors to the Gothic style.
In the same way the Parthenon is the most impressive monument for Classical religion, Hagia Sophia remained the iconic church for Christianity. The temples of these two religions differ substantially from the point of view of their interiors and exteriors. For Classical temples, only the exterior was important, because only the priests entered the interior, where the statue of the deity to whom the temple was dedicated was kept. The ceremonies were held outside, in front of the temple. Instead, Christian liturgies were held inside the churches. [4]
Byzantine columns are quite varied, mostly developing from the classical Corinthian, with the ornamentation undercut with drills, and fluted shafts almost entirely abandoned. The block of stone was left rough as it came from the quarry, and the sculptor evolved new designs to his own fancy, so that one rarely meets with many repetitions of the same design. One of the most remarkable designs features leaves carved as if blown by the wind; the finest example being at the 7th-century Hagia Sophia (Thessaloniki). Those in the Cathedral of Saint Mark, Venice (1071) specially attracted John Ruskin's fancy. Others appear in Sant'Apollinare in Classe, Ravenna (549).
The column in San Vitale, Ravenna (547) shows above it the dosseret required to carry the arch, the springing of which was much wider than the abacus of the column. On eastern columns the eagle, the lion and the lamb are occasionally carved, but treated conventionally.
There are two types of columns used at Hagia Sophia: Composite and Ionic. The Composite column that emerged during the Late Byzantine Empire, mainly in Rome, combines the Corinthian with the Ionic. Composite columns line the principal space of the nave. Ionic columns are used behind them in the side spaces, in a mirror position relative to the Corinthian or Composite orders (as was their fate well into the 19th century, when buildings were designed for the first time with a monumental Ionic order). At Hagia Sophia, though, these are not the standard imperial statements. The columns are filled with foliage in all sorts of variations. In some, the small, lush leaves appear to be caught up in the spinning of the scrolls – clearly, a different, nonclassical sensibility has taken over the design.
The columns at Basilica of San Vitale show wavy and delicate floral patterns similar to decorations found on belt buckles and dagger blades. Their inverted pyramidal form has the look of a basket.
Buildings increased in geometric complexity, brick and plaster were used in addition to stone in the decoration of important public structures, classical orders were used more freely, mosaics replaced carved decoration, complex domes rested upon massive piers, and windows filtered light through thin sheets of alabaster to softly illuminate interiors. Most of the surviving structures are sacred, with secular buildings having been destroyed.
Prime examples of early Byzantine architecture date from the Emperor Justinian I's reign and survive in Ravenna and Istanbul, as well as in Sofia (the Church of St Sophia).
One of the great breakthroughs in the history of Western architecture occurred when Justinian's architects invented a complex system providing for a smooth transition from a square plan of the church to a circular dome (or domes) by means of pendentives.
In Ravenna, the longitudinal basilica of Sant'Apollinare Nuovo, and the octagonal, centralized structure of the church of San Vitale, commissioned by Emperor Justinian but never seen by him, was built. Justinian's monuments in Istanbul include the domed churches of Hagia Sophia and Hagia Irene(both discussed in more detail below), but there is also an earlier, smaller church of Saints Sergius and Bacchus (locally referred to as "Little Hagia Sophia"), which might have served as a model for both in that it combined the elements of a longitudinal basilica with those of a centralized building.
Other structures include the ruins of the Great Palace of Constantinople, the innovative walls of Constantinople (with 192 towers) and Basilica Cistern (with hundreds of recycled classical columns). A mosaic in the church begun by the Ostrogoths, San Apollinare in Nuovo in Ravenna, depicts an early Byzantine palace.
Hagios Demetrios in Thessaloniki, Saint Catherine's Monastery on Mount Sinai, Jvari Monastery in present-day Georgia, and three Armenian churches of Echmiadzin all date primarily from the 7th century and provide a glimpse on architectural developments in the Byzantine provinces following the age of Justinian.
Remarkable engineering feats include the 430 m long Sangarius Bridge, the pointed arch of Karamagara Bridge, as well as the dome of the Church of Hagia Sophia.
In the Macedonian dynasty, it is presumed that Basil I's votive church of the Theotokos of the Pharos and the Nea Ekklesia (both no longer existent) served as a model for most cross-in-square sanctuaries of the period, including the Cattolica di Stilo in southern Italy (9th century), the monastery church of Hosios Lukas in Greece (c. 1000), Nea Moni of Chios (a pet project of Constantine IX), and the Daphni Monastery near Athens (c. 1050). All three of the later churches display the important shifts in architectural design that occurred following the end of Iconoclasm, when architectural design and decoration became more standardized. [5]
The Hagia Sophia church in Ochrid (present-day North Macedonia), built in the First Bulgarian Empire in the time of Boris I of Bulgaria, and eponymous cathedral in Kyiv (present-day Ukraine) testify to a vogue for multiple subsidiary domes set on drums, which would gain in height and narrowness with the progress of time.[ citation needed ]
In Istanbul and Asia Minor the architecture of the Komnenian period is almost non-existent, with the notable exceptions of the Elmali Kilise and other rock sanctuaries of Cappadocia, and of the Churches of the Pantokrator and of the Theotokos Kyriotissa in Istanbul. Most examples of this architectural style and many of the other older Byzantine styles only survive on the outskirts of the Byzantine world, as most significant and ancient churches and buildings were in Asia Minor. During World War I, almost all churches that ended up within the Turkish borders were destroyed or converted into mosques. Some were abandoned as a result of the Greek and Christian genocides from 1915 to 1923. Similar styles can be found in countries such as Bulgaria, Croatia, North Macedonia, Russia, Serbia and other Slavic lands, as well as in Sicily (Cappella Palatina) and Veneto (St Mark's Basilica, Torcello Cathedral).
In Middle Byzantine architecture "cloisonné masonry" refers to walls built with a regular mix of stone and brick, often with more of the latter. The exterior of the 11th- or 12th-century Pammakaristos Church in Istanbul is an example, though it is even more renowned for Late Byzantine additions discussed below.
The Paleologan period is well represented in a dozen former churches in Istanbul, notably St Saviour at Chora and St Mary Pammakaristos. Unlike their Slavic counterparts, the Paleologan architects never accented the vertical thrust of structures. As a result, the late medieval architecture of Byzantium (barring the Hagia Sophia of Trebizond) is less prominent in height.
The Church of the Holy Apostles (Thessaloniki) is cited as an archetypal structure of the late period with its exterior walls intricately decorated with complex brickwork patterns or with glazed ceramics. Other churches from the years immediately predating the fall of Constantinople survive on Mount Athos and in Mistra (e.g. Brontochion Monastery). That site also has preserved secular architecture such as the Palace of the Despots and several houses.
In the late Byzantine period, c. 1310, a highly ornate parekklesion was added to the Pammakaristos Church in Constantinople for the tomb of Michael Glabas Tarchaniotes, a Byzantine aristocrat and general who lived c. 1235 to c. 1305–08. [6] It displays the attenuated proportions favored in the late Byzantine era, as well as shifts in style in the mosaics' treatment of figures.
As early as the building of Constantine's churches in Palestine there were two chief types of plan in use: the basilican, or axial, type, represented by the basilica at the Holy Sepulchre, and the circular, or central, type, represented by the great octagonal church once at Antioch.
Those of the latter type we must suppose were nearly always vaulted, for a central dome would seem to furnish their very purpose. The central space was sometimes surrounded by a very thick wall, in which deep recesses, to the interior, were formed, as at Church of St. George, Sofia, built by the Romans in the 4th century as a cylindrical domed structure built on a square base, and the noble Church of Saint George, Thessaloniki (5th century), or by a vaulted aisle, as at Santa Costanza, Rome (4th century); or annexes were thrown out from the central space in such a way as to form a cross, in which these additions helped to counterpoise the central vault, as at the Mausoleum of Galla Placidia, Ravenna (5th century). The most famous church of this type was that of the Holy Apostles, Constantinople. Vaults appear to have been early applied to the basilican type of plan; for instance, at Hagia Irene, Constantinople (6th century), the long body of the church is covered by two domes.
At Saint Sergius, Constantinople, and San Vitale, Ravenna, churches of the central type, the space under the dome was enlarged by having apsidal additions made to the octagon. Finally, at Hagia Sophia (6th century) a combination was made which is perhaps the most remarkable piece of planning ever contrived. A central space of 100 ft (30 m) square is increased to 200 ft (60 m) in length by adding two hemicycles to it to the east and the west; these are again extended by pushing out three minor apses eastward, and two others, one on either side of a straight extension, to the west. This unbroken area, about 260 ft (80 m) long, the larger part of which is over 100 ft (30 m) wide, is entirely covered by a system of domical surfaces. Above the conchs of the small apses rise the two great semi-domes which cover the hemicycles, and between these bursts out the vast dome over the central square. On the two sides, to the north and south of the dome, it is supported by vaulted aisles in two stories which bring the exterior form to a general square.
At the Holy Apostles (6th century) five domes were applied to a cruciform plan; the central dome was the highest. After the 6th century there were no churches built which in any way competed in scale with these great works of Justinian, and the plans more or less tended to approximate to one type. The central area covered by the dome was included in a considerably larger square, of which the four divisions, to the east, west, north and south, were carried up higher in the vaulting and roof system than the four corners, forming in this way a sort of nave and transepts. Sometimes the central space was square, sometimes octagonal, or at least there were eight piers supporting the dome instead of four, and the nave and transepts were narrower in proportion.
If we draw a square and divide each side into three so that the middle parts are greater than the others, and then divide the area into nine from these points, we approximate to the typical setting out of a plan of this time. Now add three apses on the east side opening from the three divisions, and opposite to the west put a narrow entrance porch running right across the front. Still in front put a square court. The court is the atrium and usually has a fountain in the middle under a canopy resting on pillars. The entrance porch is the narthex . Directly under the center of the dome is the ambo , from which the Scriptures were proclaimed, and beneath the ambo at floor level was the place for the choir of singers. Across the eastern side of the central square was a screen which divided off the bema, where the altar was situated, from the body of the church; this screen, bearing images, is the iconostasis . The altar was protected by a canopy or ciborium resting on pillars. Rows of rising seats around the curve of the apse with the patriarch's throne at the middle eastern point formed the synthronon. The two smaller compartments and apses at the sides of the bema were sacristies, the diaconicon and prothesis . The ambo and bema were connected by the solea, a raised walkway enclosed by a railing or low wall.
The continuous influence from the East is widely shown in the fashion of decorating external brick walls of churches built about the 12th century, in which bricks roughly carved into form are set up so as to make bands of ornamentation which it is quite clear are imitated from Cufic writing. This fashion was associated with the disposition of the exterior brick and stone work generally into many varieties of pattern, zig-zags, key-patterns etc.; and, as similar decoration is found in many Persian buildings, it is probable that this custom also was derived from the East. The domes and vaults to the exterior were covered with lead or with tiling of regional variety. The window and door frames were of marble. The interior surfaces were adorned all over by mosaics or frescoes in the higher parts of the edifice, and below with incrustations of marble slabs, which were frequently of very beautiful varieties, and disposed so that, although in one surface, the coloring formed a series of large panels. The better marbles were opened out so that the two surfaces produced by the division formed a symmetrical pattern.
Ultimately, Byzantine architecture in the West gave way to Carolingian, Romanesque, and Gothic architecture. But a great part of current Italy used to belong to the Byzantine Empire before that. Great examples of Byzantine architecture are still visible in Ravenna (for example Basilica di San Vitale which architecture influenced the Palatine Chapel of Charlemagne).
As for the East, Byzantine architectural tradition exerted a profound influence on early Islamic architecture, particularly Umayyad architecture. During the Umayyad Caliphate era (661-750), as far as the Byzantine impact on early Islamic architecture is concerned, the Byzantine arts formed a fundamental source to the new Muslim artistic heritage, especially in Syria. There are considerable Byzantine influences which can be detected in the distinctive early Islamic monuments in Syria (709–715). While these give clear reference in plan - and somewhat in decoration - to Byzantine art, the plan of the Umayyad Mosque has also a remarkable similarity with 6th- and 7th-century Christian basilicas, but it has been modified and expanded on the transversal axis and not on the normal longitudinal axis as in the Christian basilicas. The tile work, geometric patterns, multiple arches, domes, and polychrome brick and stone work that characterize Muslim and Moorish architecture were influenced heavily by Byzantine architecture.
In Bulgaria, North Macedonia, Serbia, Romania, Belarus, Georgia, Armenia, Ukraine, Russia and other Orthodox countries the Byzantine architecture persisted even longer, from the 16th up to the 18th centuries, giving birth to local post-Byzantine schools of architecture.
Neo-Byzantine architecture was followed in the wake of the 19th-century Gothic revival, resulting in such jewels as Westminster Cathedral in London, and in Bristol from about 1850 to 1880 a related style known as Bristol Byzantine was popular for industrial buildings which combined elements of the Byzantine style with Moorish architecture. It was developed on a wide-scale basis in Russia during the reign of Alexander II by Grigory Gagarin and his followers who designed St Volodymyr's Cathedral in Kyiv, St Nicholas Naval Cathedral in Kronstadt, Alexander Nevsky Cathedral in Sofia, Saint Mark's church in Belgrade and the New Athos Monastery in New Athos near Sukhumi. The largest Neo-Byzantine project of the 20th century was the Church of Saint Sava in Belgrade.
One of the less famous Byzantine churches is Hagia Irene. This church served as a model church for the more famous church, Hagia Sophia. Construction on the church began in the 4th century. This was the first church that was built in Constantinople, but due to its location, it was severely damaged by earthquakes and the Nika riots, and required repair several times. The Hagia Irene is defined by its large atrium, and is in fact the only surviving building of the Byzantine Empire to have such a feature. [8]
Hagia Irene is composed mainly of three materials: stone, brick, and mortar. Bricks 70 cm x 35 cm x 5 cm were used, and these bricks were glued together using mortar approximately 5 cm thick. The building materials chosen for the construction of the church had to be lightweight, durable, and strong. Volcanic materials were chosen for this purpose, as volcanic concrete is very light and durable. Perhaps the most definite feature of the Hagia Irene is the strict contrast between the interior and exterior design. While the plain outside composed of stone and brick favors functionality, the interior is decorated in elaborate mosaics, decorative marble, and, in some places, covered in plaster. Another important characteristic of the church include two domes that follow one behind another, the first being a lower oval, and the second being a higher semi-circle. [8]
Throughout history Hagia Irene has undergone several changes. There were multiple repairs due to the Nika riots and earthquakes. When the Ottomans took over Hagia Irene they repurposed it and made a few changes, but none as drastic as what was done to Hagia Sophia. [8] Today, Hagia Irene is still standing and open to visitors as a museum. It is open everyday, except for Tuesdays.

The most famous example of Byzantine architecture is the Hagia Sophia, and it has been described as "holding a unique position in the Christian world", [9] and as an architectural and cultural icon of Byzantine and Eastern Orthodox civilization. [10] [11] [9] The Hagia Sophia held the title of largest church in the world until the Ottoman Empire sieged the Byzantine capital. After the fall of Constantinople, the church was used by the Muslims for their religious services until 1931, when it was reopened as a museum in 1935. Translated from Greek, the name Hagia Sophia means "Holy Wisdom". [12]
The construction is a combination of longitudinal and central structures. This church was a part of a larger complex of buildings created by Emperor Justinian. This style influenced the construction of several other buildings, such as St. Peter's Basilica. Hagia Sophia should have been built to withstand earthquakes, but since the construction of Hagia Sophia was rushed this technology was not implemented in the design, which is why the building has had to be repaired so many times due to damages from the earthquakes. The dome is the key feature of Hagia Sophia as the domed basilica is representative of Byzantine architecture. Both of the domes collapsed at different times throughout history due to earthquakes and had to be rebuilt. [13]
The original construction of Hagia Sophia was possibly ordered by Constantine, but ultimately carried out by his son Constantius II in 360. Constantine's building of churches, specifically the Hagia Sophia, was considered an incredibly significant component in his shift of the centralization of power from Rome in the west to Constantinople in the east, and was considered the high-point of religious and political celebration. The construction of the final version of the Hagia Sophia, which still stands today, was overseen by Emperor Justinian. Between the rule of these two Emperors, Hagia Sophia was destroyed and rebuilt twice. Following its reconstruction, Hagia Sophia was considered the center of Orthodox Christianity for 900 years, until the fall of Constantinople to the Ottomans. [14]

Constantinople became the capital of the Roman Empire during the reign of Constantine the Great in 330. Following the collapse of the Western Roman Empire in the late 5th century, Constantinople remained the capital of the Eastern Roman Empire, the Latin Empire (1204–1261), and the Ottoman Empire (1453–1922). Following the Turkish War of Independence, the Turkish capital then moved to Ankara. Officially renamed Istanbul in 1930, the city is today the second largest city in Europe, straddling the Bosporus strait and lying in both Europe and Asia, and the financial center of Turkey.
Isidore of Miletus was one of the two main Byzantine Greek mathematician, physicist and architects that Emperor Justinian I commissioned to design the cathedral Hagia Sophia in Constantinople from 532 to 537. He was born c. 475 AD. The creation of an important compilation of Archimedes' works has been attributed to him. The spurious Book XV from Euclid's Elements has been partly attributed to Isidore of Miletus.
Hagia Sophia, officially the Hagia Sophia Grand Mosque, is a mosque and former church serving as 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 AD 537. The site was a Greek Orthodox church from AD 360 to 1453, except for a brief time as a Latin Catholic church between the Fourth Crusade and 1261. After the fall of Constantinople in 1453, it served as a mosque until 1935, when it became a museum. In 2020, the site once again became a mosque.
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.
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.
Byzantine art comprises the body of artistic products of the Eastern Roman Empire, as well as the nations and states that inherited culturally from the empire. Though the empire itself emerged from the decline of western Rome and lasted until the Fall of Constantinople in 1453, the start date of the Byzantine period is rather clearer in art history than in political history, if still imprecise. Many Eastern Orthodox states in Eastern Europe, as well as to some degree the Islamic states of the eastern Mediterranean, preserved many aspects of the empire's culture and art for centuries afterward.
The Basilica Cistern, or Cisterna Basilica, is the largest of several hundred ancient cisterns that lie beneath the city of Istanbul, Turkey. The cistern, located 150 metres (490 ft) southwest of the Hagia Sophia on the historical peninsula of Sarayburnu, was built in the 6th century during the reign of Byzantine emperor Justinian I. Today it is kept with little water, for public access inside the space.
Neo-Byzantine architecture was a revival movement, most frequently seen in religious, institutional and public buildings. It incorporates elements of the Byzantine style associated with Eastern and Orthodox Christian architecture dating from the 5th through 11th centuries, notably that of Constantinople and the Exarchate of Ravenna.
The Church of the Holy Apostles, also known as the Imperial Polyandrion, was a Byzantine Eastern Orthodox church in Constantinople, capital of the Eastern Roman Empire. The first structure dated to the 4th century, though future emperors would add to and improve upon it. It was second in size and importance only to the Hagia Sophia among the great churches of the capital.
The Basilica of San Vitale is a late antique church in Ravenna, Italy. The sixth-century church is an important surviving example of early Byzantine art and architecture, and its mosaics in particular are some of the most-studied works in Byzantine art. It is one of eight structures in Ravenna inscribed on the UNESCO World Heritage List. Its foundational inscription describes the church as a basilica, though its centrally-planned design is not typical of the basilica form. Within the Roman Catholic Church it holds the honorific title of basilica for its historic and ecclesial importance.
Hagia Irene or Hagia Eirene, sometimes known also as Saint Irene, is an Eastern Orthodox church located in the outer courtyard of Topkapı Palace in Istanbul. It is the oldest known church structure in the city and one of the only Byzantine churches in Istanbul that was never converted into a mosque, alongside the Church of Saint Mary of the Mongols, as it was used as an arsenal for storing weapons until the 19th century. The Hagia Irene today operates as a museum and concert hall.
The Little Hagia Sophia mosque, formerly the Church of Saints Sergius and Bacchus, is a former Greek Orthodox church dedicated to Saints Sergius and Bacchus in Constantinople, built between 532 and 536, and converted into a mosque during the Ottoman Empire.
The Pammakaristos Church, also known as the Church of Theotokos Pammakaristos, is one of the most famous Byzantine church buildings in Istanbul, Turkey, and was the last pre-Ottoman building to house the Ecumenical Patriarchate. Converted in 1591 into the Fethiye Mosque, it is today partly a museum housed in a side chapel or parekklesion. One of the most important examples of Constantinople's Palaiologan architecture, the mosque contains the largest quantity of Byzantine mosaics in Istanbul after the Hagia Sophia and The Chora.
The Hagia Sophia is a church located in Thessaloniki, Greece. With its current structure dating from the 7th century, it is one of the oldest churches in the city still standing today. Because of its outstanding Byzantine art and architecture, in addition to its importance in early Christianity, it is one of several monuments in Thessaloniki listed as a UNESCO World Heritage Site in 1988.
Hirami Ahmet Pasha Mosque is a former Eastern Orthodox church converted into a mosque by the Ottomans. The small church, one among the 36 dedicated to Saint John the Baptist in Constantinople, was part of a monastery bearing the same name. Its full name was Saint John the Forerunner by-the-Dome. It is the smallest Byzantine church of Constantinople still extant and has never been studied.
The architecture of Istanbul describes a large mixture of structures which reflect the many influences that have made an indelible mark in all districts of the city. The ancient part of the city is still partially surrounded by the Walls of Constantinople, erected in the 5th century by Emperor Theodosius II to protect the city from invasion. The architecture inside the city proper contains buildings and structures which came from Byzantine, Genoese, Ottoman, and modern Turkish sources. The city has many architecturally significant entities. Throughout its long history, Istanbul has acquired a reputation for being a cultural and ethnic melting pot. As a result, there are many historical mosques, churches, synagogues, palaces, castles and towers to visit in the city.
In architecture, a semi-dome is a half dome that covers a semi-circular area in a building.
The Church of St. Polyeuctus was an ancient Byzantine church in Constantinople built by the noblewoman Anicia Juliana and dedicated to Saint Polyeuctus. Intended as an assertion of Juliana's own imperial lineage, it was a lavishly decorated building, and the largest church of the city before the construction of the Hagia Sophia. It introduced the large-scale use of Sassanid Persian decorative elements, and may have inaugurated the new architectural type of domed basilica, perfected in the later Hagia Sophia.
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.
Byzantine mosaics are mosaics produced from the 4th to 15th centuries in and under the influence of the Byzantine Empire. Mosaics were some of the most popular and historically significant art forms produced in the empire, and they are still studied extensively by art historians. Although Byzantine mosaics evolved out of earlier Hellenistic and Roman practices and styles, craftspeople within the Byzantine Empire made important technical advances and developed mosaic art into a unique and powerful form of personal and religious expression that exerted significant influence on Islamic art produced in Umayyad and Abbasid Caliphates and the Ottoman Empire.
