The Introducing the remarkable leader, Sultan al-Zahir Baybars:

He was not merely the builder of a magnificent mosque, but a pioneer in shaping Islamic history. A man who rose from humble beginnings to great heights, he started as a slave sold in the markets, then became one of the greatest Muslim rulers. He wrote immortal epics in the face of the Crusaders and the Mongols, achieving great victories at the battles of Mansoura and Ain Jalut. He also recaptured Antioch, eradicated the Assassins, and revived the Abbasid Caliphate in Cairo. Known for his courage, shrewdness, justice, and love of scholars, he was a great sultan whose memory is immortalized in the pages of history. Baybars died in 676 AH / 1277 CE.

The Titles of Sultan al-Zahir Baybars

A number of sultanic titles appear in the founding texts, such as:

al-Malik al-Zahir

Rukn al-Dunya wa al-Din

Sultan al-Islam wa al-Muslimin

Abu al-Fath Baybars

Qasim Amir al-Mu'minin

Khalid Allah Malikahu

These titles serve a political function in addition to their inscriptional function; they affirm the sultan's status and his religious and political authority, and link the construction of the mosque to his person and his reign.

The Mosque of al-Zahir Baybars

The Mosque of al-Zahir Baybars is one of the greatest and oldest architectural monuments from the Mamluk era in Egypt, and the third largest historical mosque in the country in terms of area after the mosques of Ahmad Ibn Tulun and al-Hakim bi-Amr Allah. The mosque extends over a vast area of ​​approximately 3 acres (about 12,600 square meters), measuring about 108 meters in length and 105 meters in width. It is surrounded by a massive wall 11 meters high, topped with battlements 1.5 meters high. It contains 60 marble columns and four spacious iwans with wide facades and expansive courtyards.

The Location and Origin

Al-Maqrizi stated that the mosque is located outside Cairo in the al-Husayniyya district, and that its site was originally a square (known as the Sultan's Camel Park or al-Qashashi/Qaraqush Square).

The Reason for Construction

Al-Maqrizi, quoting from "al-Sirah al-Zahiriyya," recounts that Sultan al-Malik al-Zahir Rukn al-Din Baybars al-Bunduqdari consulted his engineers and judges about a suitable location for building a large mosque, and the chosen site was [missing information]. The atmosphere was beautiful, so the Sultan said: No, by God, I will not make the mosque a place of beauty. The first thing I will make it is my field where I play ball and which is my recreation. So he made it his private field and a blessed mosque at the same time.

The Description and Area

Al-Maqrizi noted the mosque's immense size and grandeur, describing it as a prominent architectural masterpiece. This was later confirmed by modern studies, which identified it as one of the largest mosques in historic Cairo.

The Construction Date

It was built by the famous Mamluk Sultan, Al-Zahir Rukn al-Din Baybars al-Bunduqdari.

King Al-Zahir Baybars began construction of this mosque in the square where he used to play ball.

The Construction began in 1266 CE (665 AH) and was completed in 1268 CE. He endowed the remaining square to the mosque.

The Location

Al-Zahir Square, in the heart of the present-day Al-Zahir district, Historic Cairo, Egypt.

Al-Gish Street, Al-Zahir Square, Al-Waili district (Al-Zahir area), Cairo, Egypt.

The Architectural Design

Time has preserved many of its decorative details, both stucco and stone carvings. These remains give us a true idea of ​​the mosque's splendor and magnificence at the time of its construction.

It belongs to the Mamluk architectural style and features an open design inspired by the Ibn Tulun Mosque and the Al-Masjid al-Nawawi Mosque. The Prophet's Mosque.

It consists of a huge central courtyard surrounded by four arcades, the largest of which is the Qibla arcade.

The Exterior Architectural Design

The exterior architectural design of the Al-Zahir Baybars Mosque is characterized by a majestic, military style reminiscent of fortresses and castles. This design reflects the power and grandeur of the Mamluk state in its early days.

The Exterior Facades and Walls

Stone Facades

The mosque's four facades are constructed entirely of stone. These thick, massive walls, supported by stone buttresses, give the mosque the appearance of an impregnable fortress and reflect the military and religious character of early Mamluk architecture.

The Corner Towers

The mosque features four square towers erected at its four outer corners, a defensive architectural style reminiscent of city walls and fortresses.

The High Windows

Rectangular windows, topped with stucco arches and decorated with delicate geometric and floral motifs, were opened high in the facades to allow light and ventilation.

The Cornered Balconies

The exterior walls were crowned with crenellated stone battlements in the form of "al-Muraq" or terraced balconies, adding an aesthetic touch to the austere structure of the walls.

The Outer Moat

An outer moat surrounded the mosque for protection and rainwater drainage. It has been recently restored and cleaned.

The Projecting Entrances

The mosque is distinguished by three projecting entrances that extend beyond the facade. These entrances are located on three facades, excluding the southeastern facade (the qibla facade). This style is an extension of the entrance of the Fatimid Al-Hakim Mosque. The entrances were paved with alternating courses of white and red stone (al-Tashzish), creating a distinctive geometric decorative style.

The Main Entrance (Northwest)

It's located in the center of the facade opposite the mihrab, it is the largest of the entrances (reaching a width of approximately 12 meters) and is considered the second oldest known example of projecting doors in Cairo architecture after the Mosque of Al-Hakim bi-Amr Allah. It features a massive architectural arch surrounded by decorative niches culminating in muqarnas and other architectural embellishments. The mosque's main minaret once stood above this entrance before it was destroyed in later periods.

The Two Side Entrances

One is located on the seaward (southwest) facade and the other on the southern (northeast) facade. They lead directly to the courtyard.

The Ablaq Decoration

These entrances were constructed using alternating courses (rows) of white and red stone (the ablaq style). The northeastern entrance of the mosque is considered the oldest example of the use of ablaq stone decoration in Cairo's architecture.

The Arches and Muqarnas

The arches of the entrances are decorated with muqarnas niches and niches, along with foundation plaques that record the name of the founder and the date of construction.

The Outer Dome and Imported Materials

The Dome's Position

Although the mosque's great dome is located inside, covering the mihrab (prayer niche), its immense size (with sides measuring 20 meters) made it a prominent and complete element of the mosque's exterior skyline before its historical collapse. (It was the largest dome built over a mihrab in Egypt at the time, and it has been recently restored and rebuilt.)

The Materials and Spoils of War

Sultan Baybars used wood and marble, specially brought from the Jaffa fortress in Palestine after he conquered it and destroyed its fortifications in 1267 AD, to decorate the vital parts of the entrances and facades, in order to document his military victories as religious and architectural symbols inside the mosque..

The Interior Design

The interior architectural design of the Al-Zahir Baybars Mosque is characterized by its adherence to the "traditional layout of congregational mosques" (a central open courtyard and portico). The Al-Zahir Baybars Mosque in Cairo is considered the oldest and first large sultanic mosque built during the Mamluk era, and is regarded as a cornerstone of the state's major religious structures.

The Open Central Courtyard (Fountain)

The mosque's center is occupied by a spacious, rectangular courtyard.

The courtyard measures approximately 60 x 75 meter

Four covered porticoes surround the courtyard, directly overlooking it

The courtyard opens to the outside through three massive, monumental entrances projecting from the outer wall. The main western entrance is located directly opposite the mihrab, while the other two entrances are situated between the side walls of the courtyard (northeast and southwest).

The courtyard suffered severe damage during the French campaign and the British occupation.

It was fully restored to its former glory after a comprehensive restoration project and reopened in 2023.

The Floors

Historical Components of the Floor

The Jaffa Marble

When the mosque was first built in 1266 CE, Sultan al-Zahir Baybars brought the marble and wood used in the arcades and floors from the Jaffa Citadel in Palestine after its recapture from the Crusaders.

What They Said About the Mosque

What did al-Maqrizi say about the Mosque of al-Zahir Baybars?

The Mosque of al-Zahir Baybars is mentioned in al-Mawa'iz wa al-I'tibar bi-Dhikr al-Khitat wa al-Athar (known as al-Khitat al-Maqriziyya) by Imam Taqi al-Din Ahmad ibn Ali al-Maqrizi, who dedicated an entire chapter to describing the construction, history, and story of this mosque.

The Neglect and Vandalism Throughout the Ages

The mosque's floors and columns have been subjected to vandalism and relocation throughout history, most notably during the era of Muhammad Ali Pasha, when some of the mosque's stones and columns were moved to construct the Sharqawiyya portico at Al-Azhar Mosque.

The Current State of the Floors

(After Restoration)

The stone and Marble Floors

The floors of the Al-Zahir Baybars Mosque in Cairo underwent a complete and radical transformation as part of a massive restoration and reconstruction project that has been completed and officially opened. Completely new marble and stone floors were installed to cover the mosque's courtyard and various porticoes, based on its original Mamluk architectural style.

An Ancient Water Cistern

An ancient water cistern was discovered beneath the floor of the courtyard of the Al-Zahir Baybars Mosque in Cairo during the restoration work that the mosque underwent, which was completed in 2023.

The Discovery Location

The archaeological mission and the Arab Contractors Company discovered it beneath the mosque's open central courtyard while raising the flooring and lowering the groundwater level.

The Cleaning Work

The mosque's reconstruction plan included the complete cleaning and disinfection of this cistern to restore it to its original state and protect it from further deterioration.

The Main Purpose

It was customary in Islamic and Mamluk architecture to construct large cisterns beneath the courtyards of major mosques to store water. This provided a reserve source of water for ablution and drinking for worshippers in case of water scarcity or interruption, ensuring the uninterrupted performance of religious rites.

The Mihrab and the Massive Dome

The Mihrab

It's located in the center of the qibla wall, it was adorned with intricate marble carvings and elegant decorations. Sultan al-Zahir Baybars employed the most skilled builders and brought in luxurious marble and wood from various regions (including some from the Jaffa Citadel) to cover the mihrab and the surrounding walls of the qibla iwan with elegant marble "ablaq" decorations. The qibla wall and mihrab were distinguished by their colorful marble mosaics and stucco decorations carved in stone.

The Royal Pavilion

This area, located directly beneath the dome and preceding the mihrab, is known as the maqsurah. It was remarkably spacious, historically described as "an independent sanctuary within the mosque," and was dedicated to the sultan's comfort and protection.

The Massive Dome of the Mihrab

It's preceding the mihrab was a massive square dome, 20 meters on each side. It was the largest dome built over a mihrab in Mamluk mosques. The arches of this dome rested on massive square piers, at the corners of which were sturdy round columns.

The Design

Built in the style of the Imam al-Shafi'i Dome, and despite its later collapse, it remains a landmark in the history of Islamic architecture as the largest dome erected over a mihrab in Mamluk mosques. The original dome suffered collapse and destruction throughout history due to neglect and military transformations of the mosque (especially during the French campaign). Recently, the mosque underwent a comprehensive and massive restoration and reconstruction process that lasted for years in cooperation between Egypt and Kazakhstan. The large dome above the mihrab was rebuilt and reconstructed based on archaeological and historical research to return to its original form. The mosque was officially opened in June 2023 with high-level international attendance.

The Minbar

The wooden minbar is distinguished by its highly detailed carving. Its two sides and the two leaves of its door are decorated with star-shaped patterns and inlaid woodwork. The minbar is topped by a kiosk, which is a small inlaid wooden dome. It complements the wooden surfaces of the rest of the arcades, which were treated with lacquer paint to reveal the natural details of the aged wood.

The Four Arcades and Iwans

The central courtyard is surrounded by four iwans, each internally divided into arcades by rows of arches.

The Qibla Iwan (southeast)

is the deepest and widest of the four iwans.

It comprises six arcades of arches supported by marble columns and structural piers.

The eastern and western iwans

Surround the courtyard on both sides, sharing the same architectural plan. Each contains three arcades (rows of arches) parallel to the courtyard walls.

The northern iwan (opposite the Qibla Iwan) is the shallowest, consisting of only two arcades. This iwan is distinguished by its exterior stone facade, which contains one of the mosque's three main entrances. This particular entrance was once surmounted by the mosque's old minaret before it was destroyed due to historical factors and the French campaign.

The Interior Columns and Arches

The architectural features of the arches and columns in the Mosque of al-Zahir Baybars are distinguished by a combination of marble columns and structural piers (supports). This architectural diversity stems from the builders' desire to provide strong structural support commensurate with the mosque's vast area, especially the area surrounding the courtyard and the area preceding the mihrab.

The Characteristics of the Columns and Their Supports

The Elegant Marble Columns

Most of the arches of the interior arcades are supported by columns made of white (Carrara) marble, connected to a shaft, base, and capital, all hand-carved. Some of these precious materials were brought from the fortresses of Jaffa and Antioch.

The Transfer of Columns from the Mosque of al-Zahir Baybars

In 1812 CE (corresponding to 1227 AH), at the request of Sheikh Abdullah al-Sharqawi, the Sheikh of al-Azhar Mosque at that time, a number of marble columns and some stones were transferred from the Mosque of al-Zahir Baybars (in the al-Zahir district of Cairo) for use in the construction of the "Sharqawiyya Arcade" for students from the Sharqia region within al-Azhar. Then they were replaced with new marble columns during the last restoration. This was not limited to Al-Azhar only, but it was mentioned historically that some of the mosque's stones and columns were also taken in later periods for use in other structures such as the Nile Palace.

The Stone Pillars (Bands)

Not all arches rested on marble columns. The arches directly overlooking the open courtyard, as well as the third row of arches in the qibla portico (on the eastern side), were supported by rectangular structural piers. In the historic Mosque of al-Zahir Baybars, stone piers (rectangular structural supports) were used to support the arches overlooking the courtyard and the third row of arches in the qibla iwan, while the remaining arches rested on marble columns.

The Role and Distribution of Stone Pillars

- Supporting the Main Arches

The arches surrounding the open central courtyard rested on them.

- The Distributing Loads

They were placed in the third row of arches within the qibla iwan to increase the structural rigidity and bear the weight of the roof and arcades.

- The Architectural Harmony

They formed a geometric contrast with the elegant marble columns that supported the remaining arcade arches. Dome Support Columns

The massive dome's arches, located in front of the mihrab, rested on huge square piers. These piers featured round columns integrated into their four corners to increase their strength and support the dome's weight.

The Characteristics of the Arches

The Variety of Supports

The mosque's arches are strategically distributed. The interior arches of the arcades rest on slender marble columns, while the arches facing and overlooking the courtyard rest on more robust stone piers to withstand the elements.

The Arched Windows

The upper facades of the mosque are distinguished by windows with arches carved into the stone.

The Commemorative Arches of the Entrances

The main western (and northwestern) entrance is distinguished by a massive architectural arch surrounded by geometric decorations and muqarnas inspired by Fatimid architecture and the architecture of earlier mosques, such as the Al-Aqmar Mosque.

The Decorations and Artistic Details

The stone and Plaster Decorations

The remaining fragments today reveal an important aspect of the mosque's original decorations.

The Stone Decorations

The stone decorations are primarily found on the mosque's exterior facades, which are constructed of stone. The interior was originally built largely of brick, plaster, and marble. Plaster decorations are among the most distinctive artistic elements of the mosque, especially in the stucco windows.

The Stucco Windows

The stucco windows were widespread throughout the mosque's openings, and their decorations varied between floral and geometric designs. Studies and restoration work indicate the presence of 72 stucco windows inside, including 14 original windows in the qibla iwan, in addition to three windows created by the Committee for the Preservation of Arab Antiquities in the northeastern wall.

The Minaret's Stucco Decorations

Another striking element is the stucco decoration on the minaret's square body. Its sides are adorned with star-shaped stucco designs, adding a distinct geometric element to the minaret's ornamentation.

The Calligraphic Inscriptions

These are among the most important artistic elements of the mosque, ranging from foundation texts and Quranic verses to devotional phrases and the sultan's titles. Specialized studies indicate that the mosque's inscriptions were executed primarily in various styles of Kufic script, such as foliated and floral Kufic, in addition to the Mamluk Thuluth script.

1. The Main Foundation Inscription

Above the mosque's commemorative entrance is a stone foundation inscription. It includes the Basmala (the opening phrase "In the name of God, the Most Gracious, the Most Merciful") followed by the verse:

"Only those who believe in God and the Last Day maintain the mosques of God." It then states that the mosque was built by order of Sultan al-Malik al-Zahir Baybars.

2. The Quranic Inscriptions

Quranic verses are found throughout the mosque, including inscriptions around the entrances and windows, and on the walls.

Among the texts found in the entrance decorations are:

تَبَارَكَ الَّذِي إِنْ شَاءَ جَعَلَ لَكَ خَيْرًا مِنْ ذَٰلِكَ جَنَّاتٍ وَيَجْعَلْ لَكَ قُصُورًا

“Blessed is He who, if He wills, can grant you better than that—gardens—and grant you palaces.”

فِي بُيُوتٍ أَذِنَ اللَّهُ أَنْ تُرْفَعَ وَيُذْكَرَ فِيهَا اسْمُهُ

“In houses which God has permitted to be raised and in which His name is mentioned.”

But, the recent restoration work indicates the presence of internal stucco bands containing Quranic verses in the qibla iwan, which have been restored and treated for preservation.

2. Kufic inscriptions

Kufic inscriptions represent one of the most prominent decorative features in the mosque, especially in the calligraphic bands and decorations surrounding the window openings and some architectural elements. These inscriptions are distinguished by the fact that the letters do not only perform a textual function, but rather turn into a decorative element that is integrated with the plant decorations; therefore, the foliated Kufic and the flowery Kufic appeared in the mosque.

3. Mamluk Thuluth Script

Alongside Kufic, the Mamluk Thuluth script was used in some inscriptions. It is a script characterized by the flexibility and clarity of its letters and its ability to fill large architectural spaces. This diversity between Kufic and Thuluth reflects an important stage in the development of architectural writing during the early Mamluk period.

The Important historical milestones

The mosque witnessed harsh transformations throughout history that altered its features and function before it regained its status.

1. The Ottoman Era

(The Financial Neglect)

The mosque's vast area (approximately 3 acres) made its continuous maintenance difficult. The mosque suffered from severe neglect due to insufficient financial allocations during this period.

2. The French Campaign (1198–1201 CE)

The French converted the mosque into a military fortress known as "Solkoski Fortress" or "The Apparent Fortress."

They installed cannons atop its walls and turned its minaret into a watchtower. They also built quarters for soldiers inside. Parts of the mosque suffered cracks and collapses due to this military use.

3. The Era of Muhammad Ali Pasha

(The camp and Factory)

- In 1812, some of the mosque's columns were moved to Al-Azhar Mosque to build the Sharqawiyya Portico (for students of the Sharqia region).

- The historical edifice was converted into a camp for the Senegalese Takarna community.

- It was later used as a soap factory.

4. The British Occupation

(Animal Slaughterhouse)

- The mosque witnessed one of the worst periods of historical desecration; in 1882, following the British occupation of Egypt, the occupying army used the Al-Zahir Baybars Mosque as a storehouse for military supplies, then as a bakery, and finally as a slaughterhouse to provide meat for the British forces, until the slaughtering stopped in 1915, leading to the obliteration of its features.

The Efforts of the Committee for the Preservation of Arab Monuments and Restoration (1893–2023)

In 1893,

The Committee for the Preservation of Arab Monuments began its work on the mosque, repairing the areas surrounding the mihrab to create a prayer hall.

In 1918

the remaining courtyard of the mosque was converted into a public park by the Urban Planning Department.

In June 2023

after decades of closure and extensive restoration, the Ministry of Religious Endowments officially reopened the mosque, restoring it to its original function as a religious and historical landmark in the heart of Cairo.

In June 2026

the latest phase of its development was completed with the installation of a state-of-the-art panoramic lighting system that highlights its captivating Mamluk decorations at night.
