Although sources offer varying interpretations regarding the exact construction date and founder of Yılan Kale, it is generally accepted that the structure served a defensive purpose during the Middle Ages. Located on the historic Silk Road route crossing the Taurus Mountains, the fortress was constructed by the Byzantines as an important defensive point during the Crusades.^【2】 Architectural remains and wall repairs from the Byzantine, Crusader, and Armenian periods have been observed at the site; inscriptions from the Armenian restoration phase have been documented within the structure.^【3】

Yılan Kale is built on a steep hill overlooking the plain and features eight circular towers. The main entrance, known as the nizamiye gate, is located on the southern side; stone staircases from this gate lead to terraces. Within the fortress, structures such as a church and a cistern have been identified, and the garrison was positioned in the uppermost section.^【4】 Its strategic location allowed control over the surrounding plain and key routes.^【5】
