Islamic architecture

• 1. Introduction

  ›

  Islamic architecture is one of the most geographically sweeping building traditions in history, stretching from Western Africa and Europe all the way to Eastern Asia. It began in earnest in 622, the year Muhammad built the first mosque in Medina right after his migration from Mecca. That structure was a simple courtyard of unbaked brick measuring about 53 by 56 meters, with palm trunks holding up a shaded portico. It was modest enough that scholars debate whether it was a house or a community center from the start. Yet from that single courtyard would eventually grow minarets, muqarnas, ribbed domes, geometric tile work, and paradise gardens found across three continents. How did a regional building tradition born in seventh-century Arabia absorb and transform the architectural languages of Rome, Persia, Byzantium, and Mesopotamia? And what shared logic holds together monuments as different as the Dome of the Rock in Jerusalem and the Taj Mahal outside Agra? The answers turn out to lie not in any single origin, but in a series of encounters, experiments, and decisions made by craftsmen, caliphs, and patrons across more than fourteen centuries.

• 2. The First Mosques

  Muhammad's mosque in Medina changed twice before his death in 632. When the direction of prayer shifted from Jerusalem to Mecca in 624, a matching portico was added to the south side of the courtyard. Over the rest of the seventh century and into the eighth, repeated expansions gave the building a large flat-roofed prayer hall supported by columns, the form scholars call a hypostyle hall, with a central courtyard open to the sky. That layout became the template copied by the earliest mosques built elsewhere as Arab-Muslim forces moved out of the Arabian Peninsula. New garrison cities founded in conquered territories, places like Fustat in Egypt and Kufa in present-day Iraq, each received a central congregational mosque in the hypostyle format. In Syria, where existing cities were taken over rather than built fresh, mosques were established by converting or occupying parts of churches in cities like Damascus and Hama. None of these early structures had a minaret. Small shelters may have been built on roofs to protect the person giving the call to prayer, but the soaring tower was not yet part of the picture. The Umayyad Caliphate, which came to power in 661, changed that equation by recruiting craftsmen from across the empire and actively encouraging architects to blend elements from different traditions in ways that had no precedent.

• 3. Umayyad Innovation

  Caliph Abd al-Malik built the Dome of the Rock in Jerusalem, and al-Walid I built the Great Mosque of Damascus, which is also known as the Umayyad Mosque. Both monuments drew on late antique mosaic craftsmen and motifs, and both became touchstones for what followed. Al-Walid I also rebuilt Muhammad's mosque in Medina in 707, and it was during that rebuilding that the first mihrab appeared: a concave niche set into the wall facing Mecca that reportedly marked the spot where Muhammad stood when leading prayer. It became a standard feature of every mosque built afterward. The Umayyads also introduced the wider central aisle in front of the mihrab, almost certainly borrowing the idea from Christian basilica plans already common in Syria. Figural decoration appeared in secular palaces like Qusayr Amra, while non-figural and abstract ornamentation dominated religious buildings. The Dome of the Rock itself carries calligraphic inscriptions from the Quran that scholars have interpreted as a deliberate theological statement, quoting verses about the human nature of Jesus and the oneness of God in ways that announce the arrival of Islam and distinguish it from Christianity. The horseshoe arch also makes its first documented appearance in Umayyad architecture and would later evolve into its most complex forms in al-Andalus on the Iberian Peninsula.

• 4. Abbasid Shifts and Regional Flowering

  ›

  When the Abbasids overthrew the Umayyad Caliphate in 750, the political center of the Islamic world moved east to Baghdad in present-day Iraq, pulling architectural emphasis with it toward Sasanian and ancient Mesopotamian models. Samarra, built in the ninth century as a new capital, became a laboratory for formal experiment. The Great Mosque of Samarra, built by al-Mutawakkil, measured 256 by 139 meters and was decorated with marble panels and glass mosaics. Its minaret, the Malwiyya, rises in a spiral form that remains unique in Iraq. Samarra is also where the four-centred arch was first documented, in the Qasr al-Ashiq palace, and where decorative stucco was transformed from vegetal into more abstract stylized forms. That so-called beveled style spread quickly across the Islamic world. Meanwhile, in al-Andalus, a branch of the Umayyad dynasty had taken power in 756 and built the Great Mosque of Cordoba starting in 785-786. Its hypostyle hall with double-tiered, two-coloured arches was unlike anything in the east, and the expansion by al-Hakam II after 961 added ribbed domes whose ribs intersect off-center, leaving the central space for a smaller cupola, a structural solution that became a model for later buildings in the Maghreb and the Iberian Peninsula. The Ibn Tulun Mosque in Egypt, completed in 879, was strongly influenced by Abbasid Samarra and remains one of the best-preserved examples of ninth-century construction from that tradition.

• 5. Signature Elements

  Three ornamental systems define the visual identity of Islamic buildings across regions and centuries. The first is calligraphy. Because of the central importance of the written word in Islam, epigraphic decoration appears on virtually every surface, from foundation inscriptions naming patrons and dates to Quranic verses chosen for explicit theological purpose. The second is the arabesque, a floral motif extended into what the source describes as an infinitely repeated pattern that extends beyond the visible material world. The third is elaborate geometric patterning. Together these three systems are rendered in an unusually wide range of materials: stone carving, carved stucco, glazed tilework, glass mosaic, marble paneling, brickwork, and stained glass. Muqarnas, sometimes called honeycomb or stalactite vaults, are a fourth element particular to Islamic architecture. They are three-dimensional sculpted motifs created by subdividing a vaulting structure into miniature pointed-arch niches. The earliest surviving examples appear in the late tenth and early eleventh centuries in geographically distant locations, including the Arab-Ata Mausoleum of 977-978 in Tim in Uzbekistan, the Gunbad-i Qabus of 1006-1007 in northeastern Iran, and the Duvazdah Imam Mausoleum of 1037-1038 in Yazd. The near-simultaneous emergence in such distant places has made their origin a persistent scholarly debate. From the twelfth century onward, muqarnas appeared on cornices, portals, mihrabs, entire domes, and entrance portals, including the celebrated entrance portal of the Bimaristan of Nur al-Din in Damascus, which dates from 1154.

• 6. Domes Across Dynasties

  ›

  Mimar Sinan, the Ottoman architect, spent much of his career working on a problem left unresolved by the Hagia Sophia in Constantinople: how to support a massive central dome in a way that opened up the interior space beneath it. His Suleymaniye Mosque in Istanbul, built between 1550 and 1557, used four pillars with two flanking shield walls and two semi-domes. His Selimiye Mosque in Edirne, built between 1568 and 1574, used eight pillars with four diagonal semi-domes. Ottoman sources described the Selimiye dome as surpassing that of the Hagia Sophia. In Iran, a separate tradition developed around double-shelled domes, traceable to the eleventh century. Major Timurid monuments like the Gur-i Amir Mausoleum and the Bibi Khanum Mosque, both completed around 1404, made large double-shelled domes a marker of imperial ambition. The Gur-i Amir's dome, the oldest of its type to have survived, features an exterior ribbed profile with muqarnas around its drum. Shah Abbas initiated the reconstruction of Isfahan in 1598, and the Shah Mosque built under the Safavids reached 53 meters in height when it was finished in 1629, with 14 meters of space between the two shells of its dome resting on an octagonal chamber. The seven-colour tile style developed during the Safavid period enabled richer patterns by applying more colours to each tile. In South Asia, Mughal domes derived from the Iranian tradition but with a distinctly more bulbous profile. The Tomb of Humayun, completed around 1571-72, drew on Timurid models from Samarkand, and the Taj Mahal's central dome is also double-shelled.

• 7. Cities and Their Logic

  ›

  Early Muslim garrison settlements, called amsar in Arabic, were deliberately placed outside existing non-Muslim cities. Kufa and Basra in Iraq, Fustat in Egypt, and Kairouan in North Africa all began as these encampments and developed into urbanized commercial and administrative centers. The basic facilities built first were a mosque, a governor's residence, and a market, placed at the center. When Islamic rulers took over existing cities rather than founding new ones, the urban fabric changed more slowly. In Damascus and Aleppo, both of Roman-Byzantine heritage, Islamic presence was initially marked only by a mosque and, in Damascus, a royal palace. The underlying logic of the Islamic city differs from the European model. Streets lead from public main roads down to dead-end byroads, then inward to private plots. There are few or no connections between different quarters. To move from one quarter to another, a person must return to the main road. Individual houses orient themselves inward around courtyards rather than outward toward the street, their exterior walls largely unadorned. The source describes this spatial structure as a reflection of the ancient nomadic tradition of living in a family group, held together by asabiyyah, a bond of cohesion or family loyalty, strictly separated from the outside. The privacy hierarchy runs from the public square through the tribal quarter, through the family home, down to the inner rooms reserved for women and children, with only the family head holding unlimited access. The excavated city of Anjar in Lebanon represents a rare example of a city planned during the Umayyad period on a Roman ideal-city model, with crossing main roads in the Roman cardo and decumanus pattern.

• 8. Gardens and Sacred Space

  ›

  The tradition of the paradise garden in Islamic architecture traces back to the Achaemenid Empire, a connection preserved in Xenophon's dialogue Oeconomicus, where Socrates relates the story of the Spartan general Lysander visiting a Persian prince's paradise at Sardis. The classic form is the charbagh or chahar bagh, a rectangular irrigated space divided into four sections by axial paths meeting at a central point. A garden of this type from Achaemenid times has been identified in excavations at Pasargadae. The UNESCO World Heritage list includes a collection of Persian gardens spanning from the Fin Garden in Kashan to the Shazdeh Garden in Mahan and the Pahlevanpour Garden. The same form appears at the Taj Mahal in Agra, at Humayun's Tomb in New Delhi, at the Shalimar Gardens in Lahore, and at the Alhambra and Generalife in Granada. The courtyard, or sahn, performs a parallel function in mosque architecture. Almost every mosque contains one: an open space surrounded by halls and often a shaded arcade, used for ablutions, rest, and gathering. Sahns typically feature a central pool or fountain. Historically, because of warm Mediterranean and Middle Eastern climates, the courtyard also accommodated overflow worshippers during Friday prayers. The calligraphic inscriptions adorning the Dome of the Rock, the Safavid monuments in Isfahan executed by Ali Reza Abbasi as master calligrapher from 1598 onward, and the mihrab of elaborately carved stucco in the Fatimid Mashhad of Sayyida Ruqayya of 1133 all point to the same conviction embedded across Islamic building: that geometry, nature, and the written word are not decorative afterthoughts but the architectural argument itself.
