Gerdekkaya is a monumental portico grave. The front imitates the facade of a Doric building.

The front was restored in 1991. As you can see on the photo, the two columns had to be replaced.

Entrances from the vestibule lead into two adjoining, vaulted burial chambers.

The Hellenistic tombs were used by the Romans. Byzantine use has been proven for the right-hand burial chamber. The arkosolium on the left and right in the vestibule also dates from this period.
