Osmaniye is a provincial capital in southern Turkey nestled between the fertile Çukurova plain and the Amanos (Nur) Mountains. The province is home to Karatepe-Aslantaş, one of Turkey's finest open-air Hittite museums, the ancient city of Hierapolis Castabala, medieval Toprakkale Castle, and the cool highland plateau of Zorkun. It sits along the ancient trade route between Anatolia and the Levant, carrying layers of Hittite, Roman, Byzantine, and Ottoman heritage.
