Perched atop a small hill where the Kuseyr Creek begins, Koz Castle is a fascinating relic of the Crusader-era Principality of Antioch. Built from sturdy ashlar stones in the 12th-13th centuries, this strategic fortress once guarded important routes through the Hatay region. Though time has claimed its northern gate and leveled parts of the eastern walls, several imposing bastions still stand as silent sentinels over the landscape.
Today, visitors can explore the castle's atmospheric ruins, including remarkably preserved barn structures that hint at daily life in the medieval stronghold. The hilltop location offers panoramic views of the surrounding countryside. Wear sturdy shoes for the uneven terrain, and consider visiting in spring when wildflowers blanket the hillsides. The castle is easily accessible from Altınözü, making it a perfect stop for history buffs touring Turkey's lesser-known medieval sites.
