and inhumation inside Christian basilicas themselves. Conversely, new basilicas often were erected on the site of existing early Christian cemeteries and ''martyria'', related to the belief in
Bodily Resurrection, and the cult of the sacred dead became monumentalised in basilica form.
Traditional civic basilicas and ''
bouleuteria'' declined in use with the weakening of the
curial class () in the 4th and 5th centuries, while their structures were well suited to the requirements of congregational liturgies.
The conversion of these types of buildings into Christian basilicas was also of symbolic significance, asserting the dominance of Christianity and supplanting the old political function of public space and the city-centre with an emphatic Christian social statement.
Traditional monumental civic amenities like
''gymnasia'',
''palaestrae'', and ''thermae'' were also falling into disuse, and became favoured sites for the construction of new churches, including basilicas.
Under Constantine, the basilica became the most prestigious style of church building, was "normative" for church buildings by the end of the 4th century, and were ubiquitous in western Asia, North Africa, and most of Europe by the close of the 7th century.

Hypostyle synagogues, often built with apses in Palestine by the 6th century, share a common origin with the Christian basilicas in the civic basilicas and in the pre-Roman style of hypostyle halls in the Mediterranean Basin, particularly in Egypt, where pre-classical hypostyles continued to be built in the imperial period and were themselves converted into churches in the 6th century.

''atria'' and
''triclinia'' of élite Roman dwellings.

The function of Christian churches was similar to that of the civic basilicas but very different from temples in contemporary
Graeco-Roman polytheism: while pagan temples were entered mainly by priests and thus had their splendour visible from without, within Christian basilicas the main ornamentation was visible to the congregants admitted inside.
Christian priests did not interact with attendees during the rituals which took place at determined intervals, whereas pagan priests were required to perform individuals' sacrifices in the more chaotic environment of the temple precinct, with the temple's façade as backdrop.

party, preferred by the Theodosian dynasty, sought to wrest the use of the basilica from the Nicene partisan Ambrose.
According to Augustine of Hippo, the dispute resulted in Ambrose organising an 'orthodox' sit-in at the basilica and arranged the miraculous invention and translation of martyrs, whose hidden remains had been revealed in a Vision (spirituality), vision.
During the sit-in, Augustine credits Ambrose with the introduction from the "eastern regions" of antiphonal chanting, to give heart to the orthodox congregation, though in fact music was likely part of Christian ritual since the time of the Pauline epistles.
The arrival and reburial of the martyrs' uncorrupted remains in the basilica in time for the Easter celebrations was seen as powerful step towards divine approval.
At Philippi, the market adjoining the 1st-century forum was demolished and replaced with a Christian basilica.
Civic basilicas throughout Asia Minor became Christian places of worship; examples are known at Ephesus, Aspendos, and at Magnesia on the Maeander.
The ''Great Basilica'' in Antioch of Pisidia is a rare securely dated 4th century Christian basilica and was the city's cathedral church.
The mosaics of the floor credit Optimus, the bishop, with its dedication.
Optimus was a contemporary of Basil of Caesarea and corresponded with him c. 377.
Optimus was the city's delegate at the First Council of Constantinople in 381, so the 70 m-long single-apsed basilica near the city walls must have been constructed around that time.
Pisidia had a number of Christian basilicas constructed in Late Antiquity, particularly in former ''bouleuteria'', as at Sagalassos, Selge, Pednelissus, while a civic basilica was converted for Christians' use in Cremna.
At Chalcedon, opposite Constantinople on the Bosporus, the relics of Euphemia – a supposed Christian martyr of the Diocletianic Persecution – were housed in a ''martyrium'' accompanied by a basilica.
The basilica already existed when Egeria (pilgrim), Egeria passed through Chalcedon in 384, and in 436 Melania the Younger visited the church on her own journey to the Holy Land.
From the description of Evagrius Scholasticus the church is identifiable as an aisled basilica attached to the ''martyrium'' and preceded by an ''atrium''. The Council of Chalcedon (8–31 October 451) was held in the basilica, which must have been large enough to accommodate the more than two hundred bishops that attended its third session, together with their translators and servants; around 350 bishops attended the Council in all. In an ekphrasis in his eleventh sermon, Asterius of Amasea described an icon in the church depicting Euphemia's martyrdom.
The church was restored under the patronage of the ''patricia'' and daughter of Olybrius'','' Anicia Juliana. Pope Vigilius fled there from Constantinople during the Three-Chapter Controversy. The basilica, which lay outside the walls of Chalcedon, was destroyed by the Persians in the Byzantine–Sasanian War of 602–628 during one of the Sasanian occupations of the city in 615 and 626. The relics of Euphemia were reportedly Translation (relic), translated to a new Palace of Antiochos#Church of Saint Euphemia, Church of St Euphemia in Constantinople in 680, though Cyril Mango argued the translation never took place. Subsequently, Asterius's sermon ''On the Martyrdom of St Euphemia'' was advanced as an argument for iconodulism at the Second Council of Nicaea in 787.
In the late 4th century, a large basilica church dedicated to Mary, mother of Jesus was constructed in
Ephesus

The Basilica of the Virgin Mary was probably the venue for the 431 Council of Ephesus and the 449 Second Council of Ephesus, both convened by Theodosius II.
At some point during the Christianisation of the Roman world, Christian crosses were cut into the faces of the colossal statues of Augustus and Livia that stood in the basilica-''stoa'' of Ephesus; the crosses were perhaps intended to exorcise demons in a process akin to baptism.
In the eastern cemetery of Hierapolis the 5th century domed octagonal ''martyrium'' of Philip the Apostle was built alongside a basilica church, while at Myra the St. Nicholas Church, Demre, Basilica of St Nicholas was constructed at the tomb of Saint Nicholas.
At Constantinople the earliest basilica churches, like the 5th century basilica at the Monastery of Stoudios, were mostly equipped with a small cruciform crypt (), a space under the church floor beneath the altar.
Typically, these crypts were accessed from the apse's interior, though not always, as at the 6th century Church of St John at the Hebdomon, where access was from outside the apse.
At Thessaloniki, the Roman bath where tradition held Demetrius of Thessaloniki had been martyred was subsumed beneath the 5th century basilica of Hagios Demetrios, forming a crypt.
The largest and oldest basilica churches in Egypt were at Pbow, a coenobitic monastery established by Pachomius the Great in 330.
The 4th century basilica was replaced by a large 5th century building (36 × 72 m) with five aisles and internal colonnades of pink granite columns and paved with limestone.
This monastery was the administrative centre of the Pachomian order where the monks would gather twice annually and whose library may have produced many surviving manuscripts of biblical, Gnostic, and other texts in Greek and Coptic language, Coptic.
In North Africa, late antique basilicas were often built on a doubled plan.
In the 5th century, basilicas with two apses, multiple aisles, and doubled churches were common, including examples respectively at Archaeological site of Sbeitla, Sufetula, Tipasa, and Djémila.
Generally, North African basilica churches' altars were in the nave and the main building medium was ''opus africanum'' of local stone, and ''spolia'' was infrequently used.
The Church of the East's Council of Seleucia-Ctesiphon was convened by the Sasanian Emperor Yazdegerd I at his capital at Ctesiphon; according to ''Synodicon Orientale'', the emperor ordered that the former churches in the Sasanian Empire to be restored and rebuilt, that such clerics and Asceticism, ascetics as had been imprisoned were to be released, and their Nestorianism, Nestorian Christian communities allowed to circulate freely and practice openly.

, the Church of the East developed at typical pattern of basilica churches.
Separate entrances for men and women were installed in the southern or northern wall; within, the east end of the nave was reserved for men, while women and children were stood behind. In the nave was a ''bema'', from which Scripture could be read, and which were inspired by the equivalent in synagogues and regularised by the Church of Antioch.
The Council of 410 stipulated that on Sunday the archdeacon would read the Gospels from the ''bema''.
Standing near the ''bema'', the Laity, lay folk could chant responses to the reading and if positioned near the ''šqāqonā'' ("a walled floor-level pathway connecting the ''bema'' to the altar area") could try to kiss or touch the Gospel Book as it was processed from the deacons' room to the ''bema'' and thence to the altar.
Some ten Eastern churches in eastern Syria have been investigated by thorough archaeology.
A Christian basilica was constructed in the first half of the 5th century at Olympia, Greece, Olympia, where the Statue of Zeus at Olympia, statue of Zeus by Phidias had been noted as one of the Seven Wonders of the Ancient World ever since the 2nd century BC list compiled by Antipater of Sidon.
Cultural tourism thrived at Olympia and Ancient Greek religion continued to be practised there well into the 4th century.
At Nicopolis in Epirus, founded by Augustus to commemorate his victory at the Battle of Actium at the end of the Last war of the Roman Republic, four early Christian basilicas were built during Late Antiquity whose remains survive to the present.
In the 4th or 5th century, Nicopolis was surrounded by a new city wall.

Leonid period
On Crete, the Roman cities suffered from repeated earthquakes in the 4th century, but between c. 450 and c. 550, a large number of Christian basilicas were constructed.
Crete was throughout Late Antiquity a Roman province, province of the Diocese of Macedonia, governed from Thessaloniki.
Nine basilica churches were built at Nea Anchialos, ancient Phthiotic Thebes (), which was in its heyday the primary port of Thessaly. The episcopal see was the three-aisled ''Basilica A'', the Hagios Demetrios, Church of St Demetrius of Thessaloniki, and similar to the Church of the Acheiropoietos in Thessaloniki.
Its atrium perhaps had a pair of towers to either side and its construction dates to the late 5th/early 6th century.
The Elpidios Basilica ''Basilica B'' was of similar age, and the city was home to a large complex of ecclesiastical buildings including ''Basilica G'', with its luxurious mosaic floors and a mid-6th century inscription proclaiming the patronage of the bishop Peter. Outside the defensive wall was ''Basilica D'', a 7th-century cemetery church.
Stobi, () the capital from the late 4th century of the province of Macedonia Salutaris, Macedonia II Salutaris, had numerous basilicas and six palaces in late antiquity.
The ''Old Basilica'' had two phases of geometric pavements, the second phase of which credited the bishop Eustathios as patron of the renovations. A newer episcopal basilica was built by the bishop Philip atop the remains of the earlier structure, and two further basilicas were within the walls.
The ''Central Basilica'' replaced a

Various mosaics and sculptural decorations have been found there, and while the city suffered from the Ostrogoths in 479 and an earthquake in 518, ceasing to be a major city thereafter, it remained a bishopric until the end of the 7th century and the ''Basilica of Philip'' had its ''templon'' restored in the 8th century.

Justinianic period
Justinian I constructed at Ephesus a large basilica church, the Basilica of St. John, Basilica of St John, above the supposed tomb of John the Apostle.
The church was a domed cruciform basilica begun in 535/6; enormous and lavishly decorated, it was built in the same style as Justinian's Church of the Holy Apostles in Constantinople.
The Justinianic basilica replaced an earlier, smaller structure which Egeria (pilgrim), Egeria had planned to visit in the 4th century, and remains of a aqueduct branch built to supply the complex with water probably dates from Justinian's reign.
The Ephesians' basilicas to St Mary and St John were both equipped with Baptistery, baptisteries with filling and draining pipes: both
fonts were flush with the floor and unsuitable for infant baptism.
As with most Justinianic baptisteries in the Balkans and
Asia Minor
Anatolia (), also known as Asia Minor, is a peninsula in West Asia that makes up the majority of the land area of Turkey. It is the westernmost protrusion of Asia and is geographically bounded by the Mediterranean Sea to the south, the Aegean ...
, the baptistery at the Basilica of St John was on the northern side of the basilica's nave; the 734 m
2 baptistery was separated from the basilica by a 3 m-wide corridor.
According to the 6th century Syriac language, Syriac writer John of Ephesus, a Syriac Orthodox Church, Syriac Orthodox Christian, the Heterodoxy, heterodox Miaphysitism, Miaphysites held ordination services in the courtyard of the Basilica of St John under cover of night.
Somewhat outside the ancient city on the Ayasuluk Hill, hill of Selçuk, the Justinianic basilica became the centre of the city after the 7th century Arab–Byzantine wars.
At Constantinople, Justinian constructed the largest domed basilica: on the site of the 4th century basilica Church of Holy Wisdom, the emperor ordered construction of the huge domed basilica that survives to the present: the Hagia Sophia.
This basilica, which "continues to stand as one of the most visually imposing and architecturally daring churches in the Mediterranean", was the cathedral of Constantinople and the patriarchal church of the Patriarch of Constantinople.
Hagia Sophia, originally founded by Constantine, was at the social and political heart of Constantinople, near to the Great Palace of Constantinople, Great Palace, the Baths of Zeuxippus, and the Hippodrome of Constantinople, while the headquarters of the Ecumenical Patriarchate of Constantinople, Ecumenical Patriarchate was within the basilica's immediate vicinity.
The mid-6th century Bishop of Poreč ( or ; ) replaced an earlier 4th century basilica with the magnificent Euphrasian Basilica in the style of contemporary basilicas at Ravenna.
Some column Capital (architecture), capitals were of marble from Greece identical to those in Basilica of San Vitale and must have been imported from the Byzantine centre along with the columns and some of the ''opus sectile''.
There are Conch (architecture), conch mosaics in the basilica's three apses and the fine ''opus sectile'' on the central apse wall is "exceptionally well preserved".
The 4th century basilica of Saint Sophia Church, Sofia, Saint Sophia Church at Serdica (Sofia, Bulgaria) was rebuilt in the 5th century and ultimately replaced by a new monumental basilica in the late 6th century, and some construction phases continued into the 8th century.
This basilica was the cathedral of Serdica and was one of three basilicas known to lie outside the walls; three more churches were within the walled city, of which the Church of Saint George, Sofia, Church of Saint George was a former Roman bath built in the 4th century, and another was a former Mithraeum.
The basilicas were associated with cemeteries with Christian inscriptions and burials.
Another basilica from this period in Bulgaria was the Belovo Basilica (6th century AD).
The Miaphysitism, Miaphysite convert from the Church of the East, Ahudemmeh constructed a new basilica dedicated to Saint Sergius at ''ʿ''Ain Qenoye (or ''ʿ''Ain Qena according to Bar Hebraeus) after being ordained bishop of Dioceses of the Syriac Orthodox Church#Iraq, Beth Arbaye by Jacob Baradaeus and while proselytizing among the Bedouin of Arbayistan in the Sasanian Empire.
According to Ahudemmeh's biographer this basilica and its ''martyrium'', in the upper Tigris valley, was supposed to be a copy of the Basilica of St Sergius at Sergiopolis (Resafa), in the middle Euphrates, so that the Arabs would not have to travel so far on pilgrimage.
More likely, with the support of Khosrow I for its construction and defence against the Nestorians who were Miaphysites' rivals, the basilica was part of an attempt to control the frontier tribes and limit their contact with the Roman territory of Justinian, who had agreed in the 562 Fifty-Year Peace Treaty to pay 30,000 Solidus (coin), ''nomismata'' annually to Khosrow in return for a demilitarization of the frontier after the latest phase of the Roman–Persian Wars#Byzantine–Sasanian wars, Roman–Persian Wars.
After being mentioned in 828 and 936, the basilica at ''ʿ''Ain Qenoye disappeared from recorded history, though it may have remained occupied for centuries, and was rediscovered as a ruin by Carsten Niebuhr in 1766. The name of the modern site Qasr Serīj is derived from the basilica's dedication to St Sergius.
Qasr Serīj's construction may have been part of the policy of toleration that Khosrow and his successors had for Miaphysitism a contrast with Justinian's persecution of heterodoxy within the Roman empire.
This policy itself encouraged many tribes to favour the Persian cause, especially after the death in 569 of the Ghassanid Kingdom's Miaphysite king al-Harith ibn Jabalah (, ) and the 584 suppression by the Romans of his successors' dynasty.

Palace basilicas

In the Roman imperial period, Roman Imperial period (after about 27 BC), a basilica for large audiences also became a feature in palaces. In the 3rd century of the Christian era, the governing elite appeared less frequently in the forums.
They now tended to dominate their cities from opulent palaces and country villas, set a little apart from traditional centers of public life. Rather than retreats from public life, however, these residences were the forum made private.

Christian adoption of the basilica form
In the 4th century, once the Imperial authorities had decriminalised Christianity with the 313 Edict of Milan, and with the activities of Constantine the Great and Christianity, Constantine the Great and his mother Helena (Empress), Helena, Christians were prepared to build larger and more handsome edifices for worship than the furtive meeting-places (such as the Cenacle, cave-churches, house churches such as Santi Giovanni e Paolo al Celio, that of the martyrs John and Paul) they had been using. Architectural formulas for temples were unsuitable due to their pagan associations, and because pagan cult ceremonies and sacrifices occurred outdoors under the open sky in the sight of the gods, with the temple, housing the cult figures and the treasury, as a backdrop. The usable model at hand, when Constantine wanted to memorialise his imperial piety, was the familiar conventional architecture of the basilicas.
There were several variations of the basic plan of the secular basilica, always some kind of rectangular hall, but the one usually followed for churches had a central nave with one aisle at each side and an apse at one end opposite to the main door at the other end. In (and often also in front of) the apse was a raised platform, where the altar was placed, and from where the clergy officiated. In secular building this plan was more typically used for the smaller audience halls of the emperors, governors, and the very rich than for the great public basilicas functioning as law courts and other public purposes. Constantine built a basilica of this type in his palace complex at Trier, later very easily adopted for use as a church. It is a long rectangle two storeys high, with ranks of arch-headed windows one above the other, without aisles (there was no mercantile exchange in this imperial basilica) and, at the far end beyond a huge arch, the apse in which Constantine held state.

Development
Putting an altar instead of the throne, as was done at Trier, made a church. Basilicas of this type were built in western Europe, Greece, Syria, Egypt, and Palestine, that is, at any Early centers of Christianity, early centre of Christianity. Good early examples of the architectural basilica include the Church of the Nativity at Bethlehem (6th century), the church of St Elias at Thessalonica (5th century), and the two great basilicas at Ravenna.
The first basilicas with transepts were built under the orders of Emperor Constantine, both in Rome and in his "New Rome", Constantinople:
Around 380, Gregory Nazianzen, describing the Constantinian Church of the Holy Apostles at Constantinople, was the first to point out its resemblance to a cross. Because the True Cross, cult of the cross was spreading at about the same time, this comparison met with stunning success.
:— Yvon Thébert, in Veyne, 1987
Thus, a Christian symbolic theme was applied quite naturally to a form borrowed from civil semi-public precedents. The first great Imperially sponsored Christian basilica is that of Basilica of St. John Lateran, St John Lateran, which was given to the Bishop of Rome by Constantine right before or around the Edict of Milan in 313 and was consecrated in the year 324. In the later 4th century, other Christian basilicas were built in Rome: Santa Sabina, and Basilica of Saint Paul Outside the Walls, St Paul's Outside the Walls (4th century), and later Basilica di San Clemente, St Clement (6th century).
A Christian basilica of the 4th or 5th century stood behind its entirely enclosed Courtyard, forecourt ringed with a colonnade or arcade, like the stoa or

that was its ancestor or like the cloister that was its descendant. This forecourt was entered from outside through a range of buildings along the public street. This was the architectural ground-plan of Old St. Peter's Basilica, St. Peter's Basilica in Rome, until in the 15th century it was demolished to make way for a modern church built to a new plan.
In most basilicas, the central nave is taller than the aisles, forming a row of windows called a clerestory. Some basilicas in the Caucasus, particularly those of Armenia and Georgia (country), Georgia, have a central nave only slightly higher than the two aisles and a single pitched roof covering all three. The result is a much darker interior. This plan is known as the "oriental basilica", or "pseudobasilica" in central Europe. A peculiar type of basilica, known as three-church basilica, was developed in early medieval Georgia, characterised by the central nave which is completely separated from the aisles with solid walls.
Gradually, in the Early Middle Ages there emerged the massive Romanesque architecture, Romanesque churches, which still kept the fundamental plan of the basilica.
In First Bulgarian Empire, Medieval Bulgaria the Great Basilica, Pliska, Great Basilica was finished around 875. The architectural complex in Pliska, the first capital of the First Bulgarian Empire, included a

[1 CIC 1917, can. 1180 as quoted in ''Basilicas Historical and Canonical Development'', GABRIEL CHOW HOI-YAN, Toronto, Ontario, Canada 13 May 2003 (revised 24 June 2003). "It was not until 1917 that the Code of Canon Law officially recognized de jure churches that had the immemorial custom of using the title of basilica as having such a right to the title.81 We refer to such churches as immemorial."][The title of minor basilicas was first attributed to the church of Basilica di San Nicola a Tolentino, San Nicola di Tolentino in 1783. An older minor basilica is referred to as an "immemorial basilica".] Basilica churches are distinguished for ceremonial purposes from other churches. The building does not need to be a basilica in the architectural sense. Basilicas are either major basilicas – of which there are four, all in the diocese of Rome—or minor basilicas, of which there were 1,810 worldwide .
The Umbraculum is displayed in a basilica to the right side (i.e. the Epistle side) of the altar to indicate that the church has been awarded the rank of a basilica.
