Umayyad Mosque: Great Mosque of Damascus

The Great Mosque of Damascus (the Umayyad Mosque) is the first monumental architectural work in Islamic history and the oldest stone mosque still standing. The building served, after Mecca, as a central rallying point to unite Muslims in their faith and to consolidate Umayyad rule over the surrounding regions.

The Umayyad Caliphate established Damascus as its capital, setting the stage for the city's continued development as a living Arab-Muslim metropolis on which every subsequent dynasty has left—and continues to leave—its mark. The Umayyad Mosque is one of the largest and oldest mosques in the world; its original construction and subsequent changes have influenced Islamic architecture through their vitality, structural design, and details drawn from ancient cultures. The mosque's religious significance was enhanced by its famous medieval manuscripts and by being regarded as one of the wonders of the world because of its beauty and scale.

Introduction

The Great Mosque of Damascus (the Umayyad Mosque) is the first monumental architectural work in Islamic history and the oldest stone mosque still standing. The building served, after Mecca, as a central rallying point to unite Muslims in their faith and to consolidate Umayyad rule over the surrounding regions.

The Umayyad Caliphate established Damascus as its capital, setting the stage for the city's continued development as a living Arab-Muslim metropolis on which every subsequent dynasty has left—and continues to leave—its mark. The Umayyad Mosque is one of the largest and oldest mosques in the world; its original construction and subsequent changes have influenced Islamic architecture through their vitality, structural design, and details drawn from ancient cultures. The mosque's religious significance was enhanced by its famous medieval manuscripts and by being regarded as one of the wonders of the world because of its beauty and scale.

Construction history

The site of the Umayyad Mosque contains sacred buildings dating back thousands of years, each transformed over time to suit the prevailing faith. The ancient Aramaic temple dedicated to the god Haddad is the oldest layer discovered in archaeological excavations. During the Roman period it became a temple for Jupiter, the god of rain, and the site was then the largest temple in Syria.

In the fourth century, when the Roman Empire adopted Byzantine Christianity, Emperor Theodosius (ruled 379–395) converted the building into a church. It was later expanded to form St. John's Cathedral, located on the west side of the ancient temple, and the cathedral became the seat of the second-highest bishop of the Patriarchate of Antioch.

Period of the Umayyad Caliphate

The Umayyad dynasty ruled the Islamic world from 661 to 750 AD. After they came to power, Damascus became the capital of the Islamic state. During the reign of the first Umayyad caliph, Muawiya ibn Abi Sufyan, Muslims and Christians shared St. John's Cathedral: Muslims prayed in the eastern part, called the chapel, while Christians used the western side. This shared use continued until the reign of Caliph al-Walid ibn Abd al-Malik, when the prayer space was no longer sufficient—both in capacity and in the need for an architectural monument representing the new religion.

Al-Walid negotiated with Christian leaders to obtain the site; in return he promised that all other churches in the city would remain safe and that Christians would receive a new church dedicated to the Virgin Mary as compensation. The mosque was then built between 705 and 715 by order of Caliph al-Walid I.

When construction began, the remaining Roman and Byzantine elements on the site were removed to make way for an innovative grand mosque planned according to Islamic principles.

The plan of the Umayyad Mosque reflected the rising political stature of the Muslim world as a major power. Its majestic presence became a model for mosques built throughout newly conquered lands.

Thousands of workers and artists took part in the construction over nine years. The cost was large; funding came from war spoils and taxes on Damascus's inhabitants. Unlike the simpler mosques of the period, the Umayyad Mosque followed a large basilica plan with three parallel aisles and a central courtyard aligned to lead from the entrance to the mosque to the mihrab — the second concave niche in the world (place of prayer).

The mosque is known for its rich marble paneling and for an extensive gold mosaic of floral motifs covering about 4,000 square meters (43,000 square feet), which is likely one of the largest such mosaics in the world.

Abbasid Caliphate Period

Under Abbasid rule (750–860), new structures were added, including the treasury dome and the Minaret of the Bride, while the Mamluks (1260–1516) carried out major restorations and added the Qaitbay minaret. The Umayyad Mosque helped invent and shape early Islamic architecture and influenced other major mosque complexes—such as the Great Mosque of Córdoba in Spain and Al-Azhar Mosque in Egypt—based on its model. Although the original structure has been altered several times by fires, war damage, and repairs, the mosque remains one of the few that has preserved the same general form and architectural features of its eighth-century construction and retained its Umayyad character.

Engineering Design

The mosque's plan is a rectangle measuring 97 m × 156 m, with a courtyard on the north side enclosed on four edges. The sanctuary occupies the southern part of the rectangle, so the outer wall has three gates that open to the city from the north, east, and west. The southern outer wall bordering the sanctuary has a door that opens directly to the outside. The rectangular stone pavement of the nave was repaired repeatedly over the mosque's history, so its surface became uneven and higher than the original ground level. The original Umayyad paving level has recently been restored with patterned stone.

The courtyard contains three main features: an ablution basin covered by a dome supported on columns, the treasury dome on the western side supported by eight Corinthian columns, and the Dome of Zine El Abidine on the eastern side, also supported by eight columns. Stone columns and buttresses—alternating with single piers between pairs of columns—support the portico around the nave. The double-height portico is asymmetrical along the nave because the 1759 earthquake destroyed the northern part; it was later rebuilt without columns and with a different type of stucco applied to the stronger supporting piers.

Three arcades parallel to the qibla form the inner sanctuary space and are supported by two rows of Corinthian stone columns. Each portico has two levels: the lower with large semicircular arches and the upper with double arches (the same pattern repeats in the nave portico). The three arcades meet in the middle with a larger, higher portico perpendicular to the qibla wall and opposite the mihrab and minbar. The main octagonal dome, the Eagle Dome, rests on this wide portico and reaches 36 meters in height. This dome has openings, and in the eastern part of the sanctuary, between the columns of the portico, there is a small classical marble structure that holds the tomb of St. John the Baptist—known in the Qur'anic tradition as the Prophet Yahya. (A sixth-century Christian tradition linked the earlier church structure to John the Baptist, claiming his head was buried there.)

The mosque's outer walls date from Roman times, when the site served as a temple; four defensive towers stood at the corners, but only the two southern towers remained by the time al-Walid began his project. These towers became the foundations for the eastern and western minarets. A third tower-shaped minaret, the Minaret of the Bride, stands near the northern gate. Its lower part remains original; the middle section is an Ayyubid addition built after the fire of 1174. The eastern minaret, the Minaret of Jesus, reflects different architectural styles corresponding to changing political contexts: it has a Mamluk base and an Ottoman upper section due to renovation after the 1759 earthquake. The western minaret is notable for its stone inscriptions, which were restored in 1488 and again after Timur's 1401 conquest.

Two main materials were used for cladding: mosaics and marble. The mosaic tesserae combine colored glass particles, gold- and silver-leafed glass, and pieces of stone and marble to create a reflective surface decorated with geometric and floral patterns. Mosaics originally covered the upper parts of the sanctuary walls (inside and outside), arcades, arches, and the lower sides of vaults. The painted compositions also formed picturesque scenes meant to evoke Damascus's landscapes—such as the Barada River, which flows along the great Umayyad palaces and their fruit groves—an imagined view of the countryside and sky.

Highly veined marble was used to clad the lower parts of the walls because it is more durable than mother-of-pearl mosaics. Marble slabs were attached to the wall up to a height of about four meters above the ground, and their veining was used to form decorative patterns.

Only small holes now remain where these panels were fixed to the walls. A richly carved marble band separated the marble cladding from the mosaics; its plant-inspired designs were known as the "great golden vines" because they resembled interlocking vine motifs common in the classical Roman and Byzantine periods. Fragments of this famous band still survive in the mosque. Ottoman blue-glazed tiles later replaced missing marble slabs in the nave.

Inscribed text filled the gaps between decorative elements, adding another layer of detail to the walls. Verses, dates, and dedications to various patrons were also used when restoring parts of the mosque. These inscriptions were often executed in mosaics using two contrasting colors—usually gold script on a royal blue background.

Religious significance

The mosque is the fourth-holiest site in Islam. A Christian tradition dating back to the sixth century linked the earlier cathedral structure to John the Baptist, and legend held that his head was buried there. Ibn al-Faqih reports that during the mosque's construction workers discovered a cave chapel containing a box with the head of John the Baptist, whom Muslims know as Yahya ibn Zakaria. When al-Walid examined it, he ordered the head to be reburied beneath a certain pillar in the mosque, later inlaid with marble.

The site holds great significance for both Shia and Sunni Muslims. It became the destination of the women and children of the Prophet Muhammad's family who were forced to march here from Iraq after the Battle of Karbala; they were held there for sixty days. Two shrines commemorating the Prophet's grandson, al-Husayn ibn Ali, are located inside the complex.

According to a hadith narrated by Muslim ibn al-Hajjaj, the Great Mosque of Damascus is the place where Jesus will descend from heaven at his second coming, appearing on the "white minaret." Most Muslim theologians interpret this hadith symbolically rather than literally. In a study of Islamic sources, William Richard Oaks notes that some elements of this hadith may date to the late Umayyad period, when the mosque was built, rather than to the time of Muhammad, when Damascus had not yet been conquered by Muslims.

Conclusion

At the beginning of the eighth century, during his ten-year reign as caliph, al-Walid ibn Abd al-Malik addressed the citizens of Damascus:

"People of Damascus, four things you are superior to the rest of the world: your climate, your water, your fruit, your baths. And I wanted to add to these a fifth: this mosque."
