I wonder if one day all Middle Eastern countries, or even going further East, will have a caravanserai listed. The ones Turkey is trying to list are not one of their many generic ones but special ones call sultanhan and follow a standard building plan, including a standard service the caravan pit stops should have. Nowadays you can't see that, but the building of the Akhan (<10min away from Hierapolis and very close to Laodikeia) still reminds you of what could have been a “deluxe” service area in ancient times. That's where the pleasure stops. Akhan ia now a hotel/restaurant so visiting requires to be a guest (although walking in regardless is possible I thought it would be rude). You can see inside from the gate. There is a small sign with info in Turkish and I think most of it was about restoration rather than historical info. The building looks too good to be original, just like the caravanserai in Iran I didn't like so much. I did not travel further East to see any other examples but probably still have the chance one day so my opinion could surely change that they are more than regular caravanserai.
