Gaziantep Castle, Archaeological site and castle in central Gaziantep, Turkey.
Gaziantep Castle is a fortress located on a hilltop in central Gaziantep with stone walls and multiple defensive towers surrounding the perimeter. The structure shows construction phases from different periods and has sustained damage from seismic activity in recent years.
The Romans built the main fortress during the 2nd century on a former Hittite observation post, and later the Byzantine Emperor Justinian expanded it in the 6th century. The castle played an important role in regional control across many centuries and was shaped by different cultures.
The site now functions as the Gaziantep Defence and Heroism Panoramic Museum, displaying exhibits about the Turkish War of Independence and stories of local resistance. This focus makes the location a place where visitors encounter the values and struggles that shaped the region's modern identity.
The castle sits on elevated terrain with pathways of varying steepness, so visitors should wear sturdy footwear and allow extra time for exploration. Following earthquake damage, restoration work is ongoing, so some areas of the site may be temporarily restricted.
The castle sits at approximately 850 meters above sea level and controlled important regional trade routes through its elevated position across many centuries. This strategic location made it a hub not only for military defense but also for economic control of the area.
