Defterdar Mosque or in long form Defterdar Mahmut Efendi Mosque is a mosque located in Eyüp, İstanbul, Turkey. It was commissioned by Defterdar Nazlı Mahmut Efendi (c. 1500-1546) and built by architect Mimar Sinan in 1542 ("defterdar" was the head of the financial department in Ottoman Empire). Instead of a crescent, this mosque has "ink pot and pen" on top of its dome, representing science and culture, rather than religion. The original one was destroyed in 1997 during a storm. Ten years later, on May 30, 2007, a new one was put on top of the dome of the mosque.
