Karaköy is the steep waterfront quarter on the Galata side of the Golden Horn, and you meet two versions of it at once. Down at the water, ferries thud against the quay, gulls trail the boats crossing to Kadıköy, and the Galataport promenade lines the Bosphorus with glass and moored cruise ships. Turn uphill and the lanes narrow into design studios, roasteries and small galleries settled inside old commercial buildings. The smell shifts from diesel and fish to roasting coffee. Ship chandlers and hardware sellers still hold Perşembe Pazarı behind the quay.
The quarter grew out of Genoese Galata, the walled Latin colony that traded across the medieval Mediterranean, and it stayed polyglot for centuries: Greek, Armenian, Jewish and Levantine merchants worked the wharves below the tower. Later the late Ottoman banks lined the hill above them. Karaköy Güllüoğlu has sold the city's best-known baklava down by the ferry pier since 1949, a short walk from Kılıç Ali Paşa Camii, the mosque Sinan built in Tophane in 1580.
