This for sure will be once listed on the main WHS list. One of the most remarkable ancient places can be compared only with Palmyra or Baalbek. You can see complete layout of ancient big town with two thatres, palaces, temples, agoras, stadium, streets, arches, houses and town walls. It is advised to spare full day to see all sights there, in sunny days take plenty of water with you but there is a small restaurant on the spot as well as other amenities.
