KESİKBAŞLAR TOMB (THE TOMB OF BEHEADED PEOPLE)
During the restoration in 1956, 7 beheaded dead bodies were found here. That’s why this place was called the tomb of "beheadeds". Some researchers believe that this could be the continuation of the ancient cult of beheading.
The notice which identifies this place is visible in the right hand lower part, I take it the small entrance is the room described.
