Al-Muallaq Mosque, Ottoman mosque in old city of Acre, Israel

Al-Muallaq Mosque stands above the street between Khan al-Umdan and Khan al-Ifranj, on the edge of Acre's Old City market. Its main body is a large square prayer hall entered through a triple-domed portico, with a smaller former library room beside it. Outside, the low dome and the round base of the demolished minaret mark the building; a stairway under a covered entryway leads into the courtyard.

The building served as Acre's Ramchal Synagogue until 1746. The Arab ruler Daher al-Umar rebuilt it as a mosque in 1758, compensating the Jewish owners with a synagogue in Acre's Jewish quarter. It stands on the site of a Crusader structure that later became the gate to the Genoese quarter. The former minaret was demolished by the municipality in 1950 over safety concerns.

The mosque's name, al-Muallaq ("the suspended"), comes from its position raised above the street along the Old City market. Inside, the former synagogue's niche for the Holy Ark and Hebrew inscriptions remain in place. The small room beside the prayer hall now serves as a library.

Visitors should remove their shoes before entering and dress respectfully, with women covering their hair with a scarf. Access is possible, though it is best to check beforehand whether a visit is welcome and to avoid times of prayer.

The minaret that once stood here was demolished by the municipality of Acre in 1950, citing a public safety risk. What remains is its round base, and the mosque entrance now sits beneath it. The building began as a Crusader-era structure that later served as the gate to the Genoese quarter.
