Gaziantep has 4+ historical sites covered in this guide, led by Zeugma Archaeological Site, Dülük (Ancient Doliche) Ruins and Gaziantep Castle. Each entry below includes the practical details — what it costs, when to go, and how to plan around it.

Gaziantep, in southeastern Turkey near the Syrian border, is one of Turkey's oldest continuously inhabited cities and its undisputed culinary capital. Famous worldwide for its baklava, pistachios, and complex spiced dishes, the city pairs 2,000 years of history with a thriving modern food culture. The Zeugma Mosaic Museum — one of the world's great mosaic collections — anchors a city packed with Ottoman bazaars, ancient hilltop citadels, and a copper-craft tradition that dates back centuries.
