One of the largest mosques in Istanbul outside the borders of the historical peninsula, Nusretiye Mosque was destroyed in the Firuzağa Fire of 1823, and rebuilt in the same place upon Mahmud II’s orders and with a design by architect Kirkor Balyan. The new Nusretiye Mosque is completed in 1826. 

Also known as the Tophane Mosque, Nusretiye Mosque is located on the Meclis-i Mebusan Street, where the Tophane-i Amire Arabacılar Kışlası Mosque, built by Selim III, once stood. Destroyed in the 1823 Firuzağa Fire alongside 48 other buildings in the vicinity, the mosque was rebuilt by Mahmud II, who commissioned architect Kirkor Balyan for the task.

Nusretiye Mosque is significant as the first mosque outside the walls of Istanbul, and today is an iconic part of the historical peninsula, and valuable historical heritage site in Karaköy.
