Rumor says this mosque boasts a hidden story. It involves expansion, a famous architect, and centuries of reverence. We are standing before the Abdülkadir Geylani Camii. This is more than just a mosque. It’s a testament to faith. It is also a blend of architectural styles.
Initially, this site housed a school. Ebû Saîd el-Muharrimî, a Hanbali scholar, taught here. Abdülkâdir-i Geylânî, his student, later expanded it. He added a tekke, a Sufi religious building. In 1165-66, Abdülkâdir-i Geylânî died. He was buried here and a tomb was built in his name. This marked the beginning of the Abdülkadir Geylani Camii’s significance.
Centuries later, Süleyman the Magnificent ordered a renovation in 1534. He added a mosque next to the tomb. An almshouse, a madrasa, and dervish lodge cells were also built. Mimar Sinan, the renowned architect, designed this expansion. Construction finished in 1574. Elvendzâde Ali Pasha was the governor of Baghdad at the time.
Throughout its history, the Abdülkadir Geylani Camii underwent several repairs. Murad IV ordered work in 1638. Silâhdar Hüseyin Pasha oversaw renovations in 1674. Ahmed III initiated repairs in 1708. Abdülaziz contributed in 1865. Abdülhamid II had it repaired between 1900 and 1904. Then, between 1970 and 1974, the trustees also had it repaired. Each era left its mark on the structure of the Abdülkadir Geylani Camii.
High walls surround a large courtyard. Two monumental gates provide access from the east and west. The facade’s pointed archways imitate Seljuk style. They were renovated in 1974. The graveyard and garden wall on the south side have a modern design. The tomb and mosque are connected. Because the mosque’s plan adapted to the older tomb, there is a slight irregularity in the overall layout.
The mosque and tomb are surrounded by double porticos on three sides. Thirty-eight small domes cover the porticos. Black marble columns support these domes. Four sections above the mosque and tomb have muqarnas decorations. The rest are plain.
The tomb forms the core of the complex. It has a square plan. A dome rests on corner vaults. A small transition space reminds us of Seljuk architecture. Inside, marble and crystal glass adorn the tomb. The outer dome has carpet-patterned tiles. An Ottoman-era sarcophagus stands within. It features various inscriptions and motifs. A silver cage protects it.
Inside the mosque, an 18.5-meter dome covers the prayer hall. Eight supports hold it up. Two-story galleries are on three sides. The mihrab rises to the dome. Few windows create a dim interior. Ottoman-era tiles once decorated the mosque. They have been replaced with marble. The new minbar is simple. The dome resembles Istanbul domes more than Iraqi ones. The Abdülkadir Geylani Camii’s plan is similar to the Silivrikapı Hadım İbrahim Pasha Mosque. Its interior resembles the Fâtih Bâli Pasha Mosque.
Other structures line the courtyard. Three tombs near the east gate belong to Geylânî’s descendants. The Sheikh Abdurrahman Tomb has inscriptions from the reigns of Süleyman and Murad IV. Two-story buildings enclose the northwest of the courtyard. They house a madrasa, tekke, almshouse cells, and a library. The ground floor cells have two sections. The main space is accessed through a wide pointed arch. The upper floor rooms were planned as dormitories. They have flat-covered porticos. Muqarnas-headed wooden columns support them.
A distorted rectangular prayer area sits between the mosque and the north porticos. A Seljuk-era minaret stands in the southeast corner. Its thick shaft is decagonal up to the first balcony. Above that, it is round with a smaller cone. Another brick minaret with mosaic tile decoration rises above the west gate. A 19th-century three-story clock tower is in the southwest corner. These are Ottoman additions.
The Abdülkadir Geylani Camii stands as a testament to history. It shows faith and architectural evolution. It is a place of peace. It is also a symbol of Istanbul’s diverse heritage.
