Yılankale is a late 12th–13th century Armenian castle in Adana Province of Turkey. It is known in Armenian as Levonkla after its possible founder—King Leo I the Magnificent of the Armenian Kingdom of Cilicia. Medieval Armenian names attached to the site are Kovara and Vaner.
A hill castle, Yılankale is located on a rocky hill overlooking the east bank of the Ceyhan River, and the Bronze and Iron Age site of Sirkeli Höyük, six kilometers west of the town of Ceyhan. The building is locally known as the home of Shahmaran, a mythical creature half woman and half snake.
