Islamic architecture comprises the architectural styles of buildings associated with Islam. It encompasses both secular and religious styles from the early history of Islam to the present day. The Islamic world encompasses a wide geographic area historically ranging from western Africa and Europe to eastern Asia. Certain commonalities are shared by styles across all these regions, but over time different regions developed their own styles according to local materials and techniques, local dynasties and patrons, different regional centers of artistic production, and sometimes different religious affiliations.

Early history (up to 10th century)

Origins

The Mosque of the Prophet, standing on the site of Muhammad’s first mosque in Medina. The present-day building is the result of many reconstructions and expansions up to modern times.

The Islamic era began with the formation of Islam under the leadership of Muhammad in early 7th-century Arabia. The first mosque was a structure built by Muhammad in Medina in 622, right after his Hijrah (migration) from Mecca, which corresponds to the site of the present-day Mosque of the Prophet (al-Masjid an-Nabawi). It is usually described as his house, but may have been designed to serve as a community center from the beginning. It consisted of a simple courtyard structure built in unbaked brick, with a rectangular, almost square, floor plan measuring about 53 by 56 meters. A shaded portico supported by palm trunks stood on the north side of the courtyard, in the direction of prayer (the qibla), which was initially towards Jerusalem. When the qibla was changed to face towards Mecca in 624, a similar portico was added on the south side, facing towards that city.Muhammad and his family lived in separate rooms attached to the mosque, and Muhammad himself was buried in one of these rooms upon his death in 632. Over the rest of the 7th century and in the 8th century the mosque was repeatedly expanded to include a large flat-roofed prayer hall supported by columns (a hypostyle hall) with a central courtyard.It became one of the main models for the early mosques built elsewhere. Scholars generally agree that aside from Muhammad’s mosque/house, the architecture of the Arabian Peninsula seems to have had only a limited role in the formulation of later Islamic architecture.

Prior to the start of the Arab-Muslim conquests of the 7th century, the two major powers in the Middle East and the eastern Mediterranean world were the Byzantine (Eastern Roman) Empire and the Sasanian Empire. These two empires both cultivated their own major architectural traditions. Occupying the borderlands between these two empires – in the desert and steppe regions of Syria, Palestine, Mesopotamia and northern Arabia – were two Arab tribal client states: the Lakhmids, who were clients of the Sasanians and had their capital at al-Hira (in present-day Iraq), and the Ghassanids, who were clients of the Byzantines and protected their eastern borders.These two Arab dynasties were significant patrons of architecture in their respective regions. Their architecture is not well understood due to the scarcity of identifiable remains today, but they borrowed and adapted the architecture of their Byzantine and Sasanian suzerains. Some of their buildings are known from archeology or historical texts, such as the Lakhmid palaces of Khawarnaq and al-Sadir in al-Hira, a Ghassanid church with mosaic decoration at Nitil (near Madaba), and a Ghassanid audience hall incorporated into the later Umayyad rural residence at ar-Rusafa. The culture and architecture of the Lakhmids and Ghassanids probably played a subsequent role in transmitting and filtering the architectural traditions of the Sasanian and the Byzantine/Roman worlds to the later Arab Islamic dynasties who established their political centers in the same regions.

When the early Arab-Muslim conquests spread out from the Arabian Peninsula in the 7th century and advanced across the Middle East and North Africa, new garrison cities were established in the conquered territories, such as Fustat in Egypt and Kufa in present-day Iraq. The central congregational mosques of these cities were built in the hypostyle format.In other cities, especially in Syria, new mosques were established by converting or occupying parts of existing churches in existing cities, as for example in Damascus and Hama.These early mosques had no minaret, although small shelters may have been constructed on the roofs to protect the muezzin while issuing the call to prayer.

Umayyad and Abbasid eras

The Umayyad Caliphate (661–750) combined elements of Byzantine architecture and Sasanian architecture, but Umayyad architecture introduced new combinations of these style The reuse of elements from classical Roman and Byzantine art was still widely evident because political power and patronage was centered in Syria, a former Roman/Byzantine province.Some former Ghassanid structures also appear to have been reused and modified during this period.However, a significant amount of experimentation occurred as Umayyad patrons recruited craftsmen from across the empire and architects were allowed, or even encouraged, to mix elements from different artistic traditions and to disregard traditional conventions and restraints. Partly as a result of this, Umayyad architecture is distinguished by the extent and variety of decoration, including mosaics, wall painting, sculpture and carved reliefs.While figural scenes were notably present in monuments like Qusayr ‘Amra, non-figural decoration and more abstract scenes became highly favoured, especially in religious architecture.

They Umayyads were the first to add the mihrab to mosque design, a concave niche in the qibla wall of the mosque.The first mihrab reportedly appeared at Muhammad’s mosque in Medina when it was rebuilt by al-Walid I in 707. It seems to have represented the place where the Prophet stood when leading prayer This almost immediately became a standard feature of all mosques. In hypostyle mosques, the Umayyads also introduced the tradition of making the “nave” or aisle in front of the mihrab wider than the others, dividing the prayer room along its central axis. Several major early monuments of Islamic architecture built under the Umayyads include the Dome of the Rock in Jerusalem (built by Caliph Abd al-Malik) and the Great Mosque of Damascus (built by al-Walid I). The Al-Aqsa Mosque on the Haram al-Sharif, also in Jerusalem, was also rebuilt by al-Walid I, replacing an earlier simple structure built around 670.Both the al-Aqsa Mosque and the Great Mosque of Damascus featured a hypostyle hall and a dome above the space in front of the mihrab, and both were influential in the design of later mosques elsewhere.A number of palaces from this period have also partially survived or have been excavated in modern times. The horseshoe arch appears for the first time in Umayyad architecture, later to evolve to its most advanced form in al-Andalus (Iberian Peninsula).

The walls and minaret of the Great Mosque of Samarra built by the Abbasids in the 9th century

The Abbasid architecture of the Abbasid Caliphate (750–1513) was particularly influenced by Sasanian architecture, which in turn featured elements present since ancient Mesopotamia.Other influences such as ancient Soghdian architecture in Central Asia have also been noted. This was partly a result of the caliphate’s political center shifting further east to the new capital of Baghdad, in present-day Iraq. Features from the late Umayyad period, such as vaulting, carved stucco, and painted wall decoration, were continued and elaborated in the Abbasid period. Abbasid mosques all followed the courtyard plan with hypostyle halls. The earliest was the mosque that Caliph al-Mansur built in Baghdad (since destroyed). The Great Mosque of Samarra built by al-Mutawakkil measured 256 by 139 metres (840 by 456 ft), had a flat wooden roof supported by columns, and was decorated with marble panels and glass mosaics. The prayer hall of the Abu Dulaf Mosque at Samarra had arcades on rectangular brick piers running at right angles to the qibla wall. Both of the Samarra mosques have spiral minarets, the only examples in Iraq.A mosque at Balkh in what is now Afghanistan was about 20 by 20 metres (66 by 66 ft) square, with three rows of three square bays, supporting nine vaulted domes.While the origins of the minaret are uncertain, it is believed that the first true minarets appeared in this period. Several of the Abbasid mosques built in the early ninth century had minaret towers which stood at the northern ends of the building, opposite the central mihrab. Among the most famous of these is the Malwiyya minaret, a stand-alone tower with a “spiral” form built for the Great Mosque of Samarra.

Early regional styles

The mihrab and maqsura area of the Great Mosque of Cordoba, added to the mosque by al-Hakam II in the late 10th century

After the overthrow of the Umayyad Caliphate in 750 by the Abbasids, a new branch of the Umayyad dynasty succeeded in taking control of Al-Andalus in 756, creating the Emirate of Cordoba and reaching the apogee of its power during the Caliphate of Cordoba in the 10th century. The Great Mosque at Córdoba, built in 785–786, marks the earliest major monument of Moorish architecture in the Iberian Peninsula (Al-Andalus). This style of architecture established in Al-Andalus was also largely shared with the architecture of western North Africa (the Maghreb), from which later empires in the region would also emerge and contribute to its artistic evolution.The original Great Mosque of Cordoba was noted for its unique hypostyle hall with rows of double-tiered, two-coloured, arches, which were repeated and maintained in later extensions of the building. The mosque was expanded multiple times, with the expansion by al-Hakam II (r. 961–976) introducing important aesthetic innovations such as interlacing arches and ribbed domes, which were imitated and elaborated in later monuments in the region. The construction of Madinat al-Zahra, a new capital and monumental palace-city in the 10th century, also created an important complex of royal architecture and patronage. Smaller monuments such as the early form of the Qarawiyyin Mosque in Fez (present-day Morocco) and the Bab al-Mardum Mosque in Toledo demonstrate the prevalence of the same stylistic elements across the region.

After its initial apogee of power, the Abbasid Caliphate became partly fragmented into regional states in the 9th century which were formally obedient to the caliphs in Baghdad but were de facto independent. The Aghlabids in Ifriqiya (roughly modern-day Tunisia) were notable patrons of architecture themselves, responsible for rebuilding both the Great Mosque of Kairouan (originally founded by Uqba ibn Nafi in 670) and the Zaytuna Mosque of Tunis in much of their current forms, as well as for building numerous other structures in the region. In Egypt, Ahmad ibn Tulun established a short-lived dynasty, the Tulunids, and built himself a new capital (Al-Qata’i) and a new congregational mosque, known as the Ibn Tulun Mosque, which was completed in 879. It was strongly influenced by Abbasid architecture in Samarra and remains one of the most notable and best-preserved examples of 9th-century architecture from the Abbasid Caliphate.

Bab al-Futuh gate built by the Fatimid vazir Badr al-Jamali

In the 10th century the Fatimid Caliphate rose to power in Ifriqiya, where it built a new fortified capital at Mahdia. In 970 the Fatimids moving their center of power to Egypt and they founded another new capital, Cairo.Fatimid architecture in Egypt followed Tulunid techniques and used similar materials, but also developed those of their own. Their first congregational mosque in Cairo was al-Azhar Mosque, founded at the same time as the city (970), which became the spiritual center for the Ismaili Shi’a branch of Islam. Other notable monuments include the large Mosque of al-Hakim (founded in 990 under al-‘Aziz but completed around 1013 under al-Hakim), the small Aqmar Mosque (1125) with its richly-decorated street façade, and the domed Mashhad of Sayyida Ruqayya (1133), notable for its mihrab of elaborately-carved stucco. Under the powerful vizier Badr al-Jamali (r. 1073–1094), the city walls were rebuilt in stone along with several monumental gates, three of which have survived to the present-day: Bab al-Futuh, Bab al-Nasr, and Bab Zuweila).

Characteristics

Some characteristics of Islamic architecture were inherited from pre-Islamic architecture of that region while some characteristics like minarets, muqarnas, arabesque, Islamic geometric motifs, pointed arch, multifoil arch, onion dome and pointed dome developed later.

Gardens

Main article: Islamic garden

Shalamar Gardens, a Mughal paradise garden in Lahore, Pakistan

Gardens and water have for many centuries played an essential role in Islamic culture, and are often compared to the garden of Paradise. The comparison originates from the Achaemenid Empire. In his dialogue “Oeconomicus”, Xenophon has Socrates relate the story of the Spartan general Lysander’s visit to the Persian prince Cyrus the Younger, who shows the Greek his “Paradise at Sardis”. The classical form of the Persian Paradise garden, or the charbagh, comprises a rectangular irrigated space with elevated pathways, which divide the garden into four sections of equal size:

One of the hallmarks of Persian gardens is the four-part garden laid out with axial paths that intersect at the garden’s centre. This highly structured geometrical scheme, called the chahar bagh, became a powerful metaphor for the organization and domestication of the landscape, itself a symbol of political territory.^[

A Charbagh from Achaemenid time has been identified in the archaeological excavations at Pasargadae. The gardens of Chehel Sotoun (Isfahan), Fin Garden (Kashan), Eram Garden (Shiraz), Shazdeh Garden (Mahan), Dowlatabad Garden (Yazd), Abbasabad Garden (Abbasabad), Akbarieh Garden (South Khorasan Province), Pahlevanpour Garden, all in Iran, form part of the UNESCO World Heritage.Large Paradise gardens are also found at the Taj Mahal (Agra), and at Humayun’s Tomb (New Delhi), in India; the Shalimar Gardens (Lahore, Pakistan) or at the Alhambra and Generalife in Granada, Spain.

Courtyard (sahn)

In the architecture of the Muslim world courtyards are found in secular and religious structures.

Residences and other secular buildings typically contain a central private courtyard or walled garden. This was also called the wast ad-dar (“middle of the house”) in Arabic. The tradition of courtyard houses was already widespread in the ancient Mediterranean world and Middle East, as seen in Greco-Roman houses (e.g. the Roman domus). The use of this space included the aesthetic effects of plants and water, the penetration of natural light, allowing breezes and air circulation into the structure during summer heat, as a cooler space with water and shade, and as a protected and proscribed place where the women of the house need not be covered in the hijab clothing traditionally necessary in public.
A ṣaḥn (Arabic: صحن) is the formal courtyard found in almost every mosque in Islamic architecture. The courtyards are open to the sky and surrounded on all sides by structures with halls and rooms, and often a shaded semi-open arcade riwaq. A mosque courtyard is used for performing ablutions and as a patio for rest or gathering. Sahns usually feature a central pool or fountain to aid with ablutions, sometimes sheltered under an open domed pavilion. Historically, because of the warm Mediterranean and Middle Eastern climates, the courtyard also served to accommodate larger numbers of worshippers during Friday prayers.

Hypostyle hall

A hypostyle, i.e., an open hall supported by columns, is considered to be derived from architectural traditions of Achaemenid period Persian assembly halls (apadana). This type of building originated from the Roman-style basilica with an adjacent courtyard surrounded by colonnades, like Trajan’s Forum in Rome. The Roman type of building has developed out of the Greek agora. In Islamic architecture, the hypostyle hall is the main feature of the hypostyle mosque. One of the earliest hypostyle mosques is the Tarikhaneh Mosque in Iran, dating back to the eighth century.

Some scholars refer to the early hypostyle mosque with courtyard as the “Arab plan” or “Arab-type” mosque.Such mosques were constructed mostly under the Umayyad and Abbasid dynasties; subsequently, however, the simplicity of this type of plan limited the opportunities for further development, and as a result, these mosques gradually fell out of popularity in some egions.

Vaulting

In Islamic buildings, vaulting follows two distinct architectural styles: While Umayyad architecture in the west continues Syrian traditions of the sixth and seventh century, eastern Islamic architecture was mainly influenced by Sasanian styles and forms.

Umayyad diaphragm arches and barrel vaults

Qusair ‘Amra

In their vaulting structures, Umayyad period buildings show a mixture of ancient Roman and Persian architectural traditions. Diaphragm arches with lintelled ceilings made of wood or stone beams, or, alternatively, with barrel vaults, were known in the Levant since the classical and Nabatean period. They were mainly used to cover houses and cisterns. The architectural form of covering diaphragm arches with barrel vaults, however, was likely newly introduced from Iranian architecture, as similar vaulting was not known in Bilad al-Sham before the arrival of the Umayyads. However, this form was well known in Iran from early Parthian times, as exemplified in the Parthian buildings of Aššur. The earliest known example for barrel vaults resting on diaphragm arches from Umayyad architecture is known from Qasr Harane in Syria. During the early period, the diaphragm arches are built from coarsely cut limestone slabs, without using supporting falsework, which were connected by gypsum mortar. Later-period vaults were erected using pre-formed lateral ribs modelled from gypsum, which served as a temporal formwork to guide and center the vault. These ribs, which were left in the structure afterwards, do not carry any load. The ribs were cast in advance on strips of cloth, the impression of which can still be seen in the ribs today. Similar structures are known from Sasanian architecture, for example from the palace of Firuzabad. Umayyad-period vaults of this type were found in Amman Citadel and in Qasr Amra.

Iwans

An iwan in the Jameh Mosque of Isfahan

An iwan is a hall that is walled on three sides and open on one side. It is typically covered by a vault although this can vary.This feature was present in Sasanian architecture, though its exact origins are older and still debated. It was later incorporated into Islamic architecture. Its usage became more common and widespread under the Seljuks in the 10th century. Iwans were used in a variety of ways and arranged in varying positions in relation to the rest of the building. They are found in many types of buildings including mosques, madrasas, palaces, and caravanserais. A common layout is the four-iwan plan.

The related Persian term, pishtaq, means the entrance portal (sometimes an iwan) projecting from the façade of a building, often decorated with calligraphy bands, glazed tilework, and geometric designs.

Domes

Domes in Iran and Central Asia

Because of its long history of building and re-building, spanning the time from the Abbasids to the Qajar dynasty, and its excellent state of conservation, the Jameh Mosque of Isfahan provides an overview over the experiments Islamic architects conducted with complicated vaulting structures.

The system of squinches, which is a construction filling in the upper angles of a square room so as to form a base to receive an octagonal or spherical dome, was already known in Sasanian architecture. The spherical triangles of the squinches were split up into further subdivisions or systems of niches, resulting in a complex interplay of supporting structures forming an ornamental spatial pattern which hides the weight of the structure.

The tradition of double-shelled brick domes in Iran has been traced back to the 11th century.At the beginning of the 15th century, major Timurid monuments like the Gur-i Amir Mausoleum and the Bibi Khanum Mosque (both completed around 1404) were notable in their use of large double-shelled domes. These domes were composed of an inner shell which was visible from the interior and a larger outer shell, visible from the exterior and often of a slightly different shape. The Gur-i Amir Mausoleum’s dome, the oldest one to have survived to the present day, features an exterior ribbed profile with a band of muqarnas around its drum. However, domes of this shape and style were likely constructed earlier, as evidenced by the Sultaniyya Mausoleum in Cairo, which was built earlier in the 1350s and appears to have copied this same design from the Iranian tradition.

The “non-radial rib vault”, an architectural form of ribbed vaults with a superimposed spherical dome, is the characteristic architectural vault form of the Islamic East. From its beginnings in the Jameh Mosque of Isfahan, this form of vault was used in a sequence of important buildings up to the period of Safavid architecture. Its main characteristics are:

four intersecting ribs, at times redoubled and intersected to form an eight-pointed star;
the omission of a transition zone between the vault and the supporting structure;
a central dome or roof lantern on top of the ribbed vault.
