Typical for this area are gravestones in the form of door, symbolizing the entrance to the underworld. A lot of these are on display near the temple. Most of them are from the second century AD and on inscription mainly mention the deceased and the founders of the stone. Symbols indicate who was remembered: eagles, lions, bulls for men for instance.
On the picture: Detail of a double gravestone, for a man and his wife. The space above the left ‘door’ is decorated with a mirror and a basket, filled with wool – which are female symbols. On the right side of the picture, one can see the eagle (a male symbol) decorating the second door.
Such double gravestones are rather uncommon in Anatolia, and seem to fit in a late-Phrygian tradition.
