Most of what you see at the archaeological sites today are remnants of the Greek, Roman, or Byzantine periods. This is a picture of the pedestrian road which was originally roofed to provide shade from the Mediterranean sun. In the background you will notice the remains of a U-shaped hippodrome that was built for chariot racing in the 2nd century A.D. It was one of the biggest of its kind and could hold more than 20,000 cheering spectators. That should give you some idea of how large and influential the city must have been.
