Amir Jamal al-Din al-Ustadar Mosque is a historic mosque in the city of Cairo. It is located inside Islamic Cairo, facing the Al-Tambakshiya Street to the north and the Habas al-Rahb Street to the southeast.
The mosque was built in 1407 by and dedicated to Emir Jamal al-Din al-Ustadar, who served under the Burji Mamluk Sultan An-Nasir Faraj. The main purpose of the building is madrasa which taught all four Islamic schools of jurisprudence. It had been undergoing renovation which completed in 2001.[1] [2] [3]
The architectural style of the mosque is greatly influenced by the Mosque-Madrassa of Sultan Barquq. Although Jamal al-Din was an influential patron of many of the architectures during his era, his career was tumultuous and he was not mourned after his execution by Sultan An-Nasir. At the same time, the Sultan had attempted to tear down this mosque, but it was prevented by the qadi by erasing the name of Jamal al-Din from the mosque.[3]
