Kayseri Castle The formidable walls of Kayseri Castle were initially erected by the Roman Emperor Gordian III in the 3rd century and later restored by the Byzantine Emperor Justinian. Most of the current structure, however, dates back to the 13th century when it was extensively rebuilt by Seljuk Sultan Alaattin Keykubat I. The castle underwent repairs twice following damage caused by the Karamanoğulları and Osmanoğulları dynasties. Situated in the heart of Kayseri, the castle was strategically constructed on level ground to safeguard the key transport routes of Central Anatolia. It is divided into two sections: the Outer Castle and the Inner Castle. The Inner Castle is positioned at a higher elevation and is encircled by defensive walls, effectively serving as a distinct fortress within the larger complex. The castle features a total of 18 towers. The Outer Castle encompasses administrative buildings, residential quarters, and defensive structures designed to shield the city with its walls and bastions, encircling the ancient government halls. During the Turkish era, the fortifications surrounding the Inner Castle were strengthened and its functions were adapted. As the need for military defense diminished in the Ottoman period, residential neighborhoods were developed inside the Inner Castle, and the Fatih Mosque was constructed within its walls.
