Six Pointed Star on an Ancient City Wall

If a city is an organic entity, its walls are like the skin of a human being, and inscriptions on this wall are like tattoos. There are 4 Six-pointed star on the walls of Jerusalem, Israel, and one on the wal of Byblos, Lebanon. Here we see another one on the city wall of Diyarbakır, largest city in southeastern Turkey,

which was built before the Roman era, but it is not clear when was this star inscripted.
