The Mansouri Great Mosque (also known as the Grand Mansouri Mosque, Great Mosque of Tripoli; ar|المسجد المنصوري الكبير) is a mosque in Tripoli, Lebanon. It was built in the Mamluk period, from 1294 to 1298. This was the first building to be erected in Mamluk Tripoli. The Grand Mansouri Mosque was built on the ruins of an earlier Crusader church. The current minaret tower was probably part of the Church of St. Mary, possibly with Lombard elements. The mosque's main entrance also appears to incorporate a former Crusader church gate. The rest of the mosque, however, is a Muslim creation dating from after the Mamluk conquest of the city. The Grand Mansouri Mosque is one of the most important historical landmarks of Mamluk-era Tripoli.
The mosque was built on the site of a former Crusader suburb near the Castle of Saint-Gilles (Tripoli Citadel), and has been mistaken for a repurposed Christian church by medieval travelers like al-Nabulsi, and modern historians. The main entrance and the minaret tower are the only remnants of a previous Crusader church, known from contemporary sources as the church of Marie de la Tour (Mary of the Tower). The church fell in disrepair following the massive earthquakes in 1170 and 1201; and as a result of the Mamluk sultan al-Manṣur Qalawun's siege of the city. Although the main entrance and minaret tower originated from a previous Christian structure, the mosque’s core elements—including its courtyard, arcades, fountain, and prayer hall are distinctly Islamic.
Known as the Jami al-Mansuri al-Kabir (Great Mansouri Mosque), the mosque was named after al-Manṣur Qalawun, who conquered Tripoli from the Crusaders in 1289. Inscriptions in the mosque reveal that Qalawun's sons, Sultans al-Ashraf Khalil and al-Nasir Muhammad, were responsible for its construction in 1294 and the addition of the courtyard arcades in 1314, respectively.
Six madrasas were built around the mosque during the Mamluk period: al-Khayriyya Hasan Madrasa (or after), al-Qartawiyya (founded), al-Nuriyya (14th century), al-Shamsiyya (1349), al-Nasiriyya (1354–1360) and an unidentified "Mashhad" Madrasa.
The mosque played a social, political, and cultural role primarily during the colonial period, when the mosque served as the site for non-violent resistance movements against the French Mandate authorities.
The Great Mosque is situated in Tripoli's historical center, in an-Nuri neighborhood, on the left bank of the Kadisha River, at the foot and west of the Tripoli Citadel.
The Great Mosque covers an area of approximately . While its facade is relatively simple, the mosque is easily recognized by its prominent minaret and main northern gate, which are the only remains of the Christian church that existed on the site. Some scholars hold that the preexisting church was converted into a mosque with only minor Mamluk modifications, rather than being largely new construction; these views, however, are not widely accepted and are primarily based on outdated 19th-century Orientalist scholarship.Crusader craftsmanship is especially visible in the main entrance's design and ornamentation: This rectangular door is framed by a series of arches featuring alternating plain and zigzag stone moldings, which rest on two slender white marble colonnettes and four narrow wall segments. The entrance is preceded by a cross-vaulted passageway. The zigzag motif, known as "chevron" or "dogtooth," has a clear Norman origin and was introduced to the Levant by the Crusaders. A closer examination reveals distinctive elements that clarify the doorway’s origins. Behind the main entrance, a row of spiky quatrefoil rosettes decorates the inner side of the arched entryway. These rosettes are not found in Muslim decorative tradition, making it unlikely that a Muslim architect would create them for an Islamic arch. In contrast, identical rosettes appear in Western architecture from the twelfth and thirteenth centuries, particularly in Crusader structures in Syria and Palestine. Similar four-petaled rosettes can be seen in Norman architecture throughout Europe, including some Norman buildings in the Levant.The layout of the Great Mosque follows a traditional Islamic arrangement, featuring a central courtyard bordered by single porticoes on the north, east, and west sides, the porticoes consist of identical low arches, complemented by a continuous corridor with simple cross-vaulting behind. The courtyard's qibla side is bordered by a double-vaulted portico leading to the mosque's prayer hall. In line with tradition, the mosque has three axial entrances aligned to the north, east, and west, supplemented by two additional entrances flanking the prayer hall. English architectural historian K. A. C. Creswell posits that the three axial entrances are characteristic of Syrian architecture, originating by chance in the Umayyad mosque in Damascus. Upon entering the courtyard, visitors will notice two granite columns rising from the pavement to the right of the main entrance. These remnants from classical times appear to serve no practical or decorative purpose, similar to the two columns in front of Taynal's mosque and the Madrasa Saqraqiyya. The riwaqs were constructed by al-Malik al-Nasir in 1314 when he completed the mosque. At the center of the courtyard, the three-tiered wudu fountain consists of two adjoining square units, one of which is topped with a dome. Al-Nabulsi, who visited Tripoli in 1700, described the fountain as "having a huge dome and pillars so large that four men would be needed to embrace them."
The prayer hall measures 51.5m (169feet) by 11.3m (37.1feet) and occupies the entire qibla side of the mosque. It is divided into two aisles by six large piers, creating fourteen areas—thirteen covered by simple cross-vaults and the area in front of the mihrab topped by a small dome. The qibla wall features three mihrabs: a main axial mihrab with a rosette above it, accompanied by two side mihrabs and a minbar. The minbar is wooden, adorned with intricate geometric carvings. Above it, a painted rosette—reused from an earlier context—displays the word Allah in its center, with decorative motifs similar to those found at the main entrance. The rosettes in relief surround the circumference of the roundel, with a zigzag pattern forming circles within. This decorative rosette, akin to the style seen at the entrance, likely originated from the same Crusader church.
The square-towered minaret, consisting of four levels, has undergone numerous restorations. Over the last level, an octagonal topped by a conical dome, was added in later times. The minaret's first floor is windowless, the second floor features two arched windows with a central column on each of its four sides. The third and fourth floors have three arched windows on the north and south sides, and two on the east and west ones. The minaret likely belonged to the Crusader Church of St. Mary, which is known to have stood near the base of the Citadel. Although Arab historical records do not detail its distinctive characteristics, Western scholars have debated its unusual form since the 19th century. French diplomat and historian Marquis Melchior de Vogüé, and Swiss historian Max van Berchem diplomat and historian, noted the resemblance between the tower and Christian bell towers of Lombardy in Italy.
The building features four inscriptions, two of which document the construction date and the names of its founders. The first inscription, located above the main entrance lintel, measures 260cm (100inches) by 39cm (15inches), and is composed of three lines written in naskh script. It reads: In the left corner between the main entrance lintel and the arch, three short additional lines are tightly inscribed. They mention the name of the moqsue architect and read:The second inscription is located on the eastern wall of the arcade surrounding the mosque's courtyard and marks the mosque's completion. It is inscribed on a white marble plaque, featuring ten lines of naskh script. The inscription reads:A third inscription, found on a secondary mihrab to the left of the main mihrab, contains four lines of naskh. It records that in 1478, Usindamur ordered the marble revetment of the mihrab:The fourth inscription is located on the mosque's minbar, featuring two lines in naskh script. It identifies the donor as Amir Qaratay, the twice-governor of Tripoli, from 1316 to 1326 and from 1332 to 1333, and dates the minbar’s construction to 1326. The inscription reads:
A hair from the beard of the Prophet Muhammad is stored in the Mansouri Great Mosque. This relic was a gift from Ottoman Sultan Abdul Hamid II to the people of Tripoli in 1891 AD. The gift was presented in recognition of the loyalty of the Tripoli residents to the Ottoman Empire and was sent after the restoration of the Hamidy Mosque. Originally intended for this mosque, the relic was instead placed in the Mansouri Great Mosque, which was larger and more central to the city. The relic is preserved in a golden box and kept in a specially built room within the Mansouri Great Mosque, referred to as the "Room of the Noble Relic." This room has been renovated and transformed into a small religious museum. The relic, is considered one of the most valuable Islamic religious items in Lebanon and is traditionally visited on the last Friday of Ramadan and on the Prophet's birthday. The room also displays other Islamic historical objects, adding to its significance as a cultural and religious site in Tripoli.
