Gaziantep Castle was originally built by the Hittite kingdoms on a high hill and dominate the surrounding land. With the growth of the population and the expansion of the city, the castle became the center of the city, and while the Hittites built a small lookout point that was later expanded into a full castle by the Roman Empire in the second and third centuries After Christmas, it remained that way for generations, and during the reign of Emperor Justinianus, it was expanded to the final size known today. In 2000 the castle was renovated and restored, and now it stands as a museum to celebrate the heroism and defense of Gaziantep against the French forces that tried to invade after the fall of the Ottoman Empire.
