Gaziantep Castlevisitor guide.

Rising atop a 25-to-30-meter-high mound on the southern bank of Alleben Creek in the city center, Gaziantep Castle stands as one of the finest surviving fortress monuments in Türkiye. The site preserves a layered past spanning from a 6,000-year-old Chalcolithic mound to the Roman-era garrison city of Theban.
