The lovely red wooden Kuleli Mosque was built in 1720 by Kaymak Mustafa Pasha, son-in-law of Ahmed III’s powerful grand vizier, Nevşehirli İbrahim Pasha, at the height of the Tulip Period, a great flowering of the arts. Both Mustafa Pasha, an admiral of the fleet, and his father-in-law were executed when the revolutionary Patrona Halil brought the Tulip period to a bloody end in 1730, and the sultan was deposed. In 1980, the mosque was restored by the Sabancı Foundation. From its terrace, you can get a fine view upstream to the nearby Kuleli Military School.
