Gaziantep Castle
A landmark citadel on a hill in the centre of Gaziantep, one of Turkey's best-preserved castles, built on a mound of great antiquity.
On September 30, 2026 the Ministry’s listing showed this museum as closed to visitors. Check the official page before planning a visit.
About the museum
Gaziantep Castle stands on a hill some 25 to 30 metres high in the middle of the city, on the south bank of the Alleben stream. It is regarded as one of the finest surviving castles in Turkey, and its bulk is hard to miss from almost anywhere in the old centre.
Nobody knows exactly when or by whom it was first built. What is clear is that the hill is an ancient mound whose history goes back some 6,000 years to the Chalcolithic period. Excavations show that in Roman times it was used as a lookout point, and a small town called Theban is known to have stood around it in the second and third centuries AD.
Over time the mound was enlarged and turned into the fortress we see today, and much of the castle's story remains hidden like a secret.
Tips
- The official listing currently shows the castle as closed, and Müzekart is not valid here, so check the Ministry's page for the latest status.
- Gaziantep's Zeugma Mosaic Museum and Archaeological Museum are close by.
