The Great Mosque of Kairouan, also known as the Mosque of Uqba (Arabic: جامع القيروان الأكبر), stands at the spiritual and historical heart of the Medina of Kairouan in central Tunisia. Rebuilt in its present and largely preserved form in AD 836 under the Aghlabid dynasty, it is one of the oldest and most influential monuments of Islamic civilisation in North Africa. More than an architectural landmark, the mosque represents the moment when Islam became firmly rooted in the Maghreb, shaping religious practice, urban life, and intellectual traditions for centuries.

A Sacred Legacy Through the Ages
The origins of the Great Mosque are inseparable from the foundation of Kairouan itself. In AD 670, the Arab general Uqba ibn Nafi established the city as a military encampment during the early Islamic expansion into North Africa. At its centre, he founded a simple oratory that marked the first Muslim place of worship in the Maghreb. This act transformed Kairouan into a permanent religious and administrative base, rather than a temporary military outpost.
Over the following centuries, the mosque endured periods of destruction, rebuilding, and enlargement, reflecting the political instability of early Ifriqiya. The most decisive transformation occurred in AD 836, when Ziyadat Allah I of the Aghlabid dynasty ordered a complete reconstruction. This rebuilding established the mosque’s essential layout and monumental character. Although later dynasties—including the Fatimids, Zirids, and Hafsids—introduced repairs and limited modifications, the Aghlabid design has remained remarkably intact, making the mosque a rare and invaluable witness to early Islamic architecture.
Architectural Brilliance of the Great Mosque
The Great Mosque forms a vast quadrilateral measuring approximately 135 meters by 80 meters, covering more than 9,000 square meters. Its layout reflects the classical hypostyle mosque plan that later spread across the Islamic world. The northern section is dominated by a wide marble-paved courtyard surrounded by porticoes. Carefully engineered with a slight slope, the courtyard channels rainwater into underground cisterns, demonstrating a sophisticated understanding of hydraulic engineering in the 9th century.
At the northern end of the courtyard rises the monumental square minaret, approximately 32 meters high. Built in three stacked levels, it is widely regarded as the oldest surviving minaret in North Africa. Its massive, almost fortress-like appearance recalls Roman watchtowers and lighthouses, illustrating how early Islamic builders adapted local and late antique architectural forms to new religious functions.
The southern section contains the hypostyle prayer hall, composed of 17 parallel naves supported by an extraordinary forest of 414 columns made of marble and porphyry. Most of these columns were reused from Roman and Byzantine buildings in Carthage, Sousse, and other ancient cities. This reuse of spolia was both practical and symbolic, linking the new Islamic monument to the deep classical past of the Mediterranean world.
The mihrab, indicating the direction of Mecca, is among the most richly decorated elements of the mosque. It is adorned with 9th-century lustre tiles imported from Baghdad, evidence of strong artistic and commercial connections between Ifriqiya and the Abbasid heartlands. Nearby stands the celebrated wooden minbar, crafted from Indian teak and assembled from more than 300 intricately carved pieces. As the oldest surviving minbar in the Islamic world, it is a key object for the study of early Islamic woodwork and decorative art.
“The Great Mosque of Kairouan is not only a place of worship but a living testament to the birth of Islamic art and architecture in North Africa.”

Spiritual and Intellectual Importance
Beyond its architectural significance, the Great Mosque of Kairouan played a central role in the intellectual history of the Islamic West. From the 9th to the 11th century, it functioned as a major centre of learning where scholars gathered to study theology, law, grammar, mathematics, astronomy, and medicine. The mosque was particularly influential in the development and dissemination of Maliki jurisprudence, which later became dominant across North and West Africa.
For many centuries, Kairouan was regarded as the fourth holiest city in Islam, after Mecca, Medina, and Jerusalem. Pilgrimage to Kairouan carried deep spiritual meaning, especially for believers unable to undertake the long journey to Mecca. This religious prestige ensured the city’s continued importance even after political power shifted elsewhere.
The Iconic Minaret
The square minaret of the Great Mosque is one of the earliest known examples in Islamic architecture. Its three-tiered structure served both religious and strategic purposes, acting as a call-to-prayer tower and a lookout over the surrounding plain, symbolising faith, authority, and permanence.
Legacy and Architectural Influence
Recognised under UNESCO criterion (ii), the Great Mosque of Kairouan exerted a profound influence on later Islamic architecture throughout the Maghreb and al-Andalus. Its hypostyle plan, minaret form, decorative vocabulary, and use of spolia became reference points for later mosque construction. Nearby, the Mosque of the Three Gates, built in AD 866, further illustrates Kairouan’s importance, featuring the oldest known sculpted mosque façade in Islamic architecture.
How to Get to Kairouan
Kairouan is located in central Tunisia and, while it is not connected to the national railway network, it is easily accessible by road from the country’s major cities. Travel to Kairouan also offers insight into the historical geography of Tunisia, as the city was deliberately founded inland for strategic and religious reasons.
From Tunis, the capital, visitors can reach Kairouan in approximately two hours. Shared taxis known as louages depart frequently and are the fastest and most flexible option. Long-distance buses also operate regularly and offer a more economical alternative.
From Sousse, one of Tunisia’s major coastal cities, buses and louages connect directly to Kairouan in about two hours. There is no direct public transport from El Djem; travellers must change in Sousse.
From Hammamet, visitors usually travel first to Tunis or Sousse and then continue to Kairouan by louage or bus. From Sfax, located in southern Tunisia, regular bus and louage services provide access to the city.
Both the bus station and the louage station are located to the northwest of the Medina. Drivers will often drop passengers near a Medina gate if requested, allowing easy access to the historic centre and the Great Mosque itself.
Conclusion
The Great Mosque of Kairouan is far more than a historic monument. It is a living record of early Islamic civilisation in North Africa, where architecture, faith, scholarship, and political history intersect. For historians, it offers a rare opportunity to study a major early mosque that has preserved its original form and function across more than twelve centuries, standing as a timeless witness to the foundations of Islamic culture in the Maghreb.
An interesting discussion is worth comment. I think that you should write more on this topic, it might not be a taboo subject but generally people are not enough to speak on such topics. To the next. Cheers
