Turkey: Hierapolis-Pamukkale

Score: 45

"The Hellenic-Roman ancient city has always been impressive, the opportunity to swim in the baths is irresistible, and the association of the city with Philip the Apostle and soothsaying priests and priestesses is intriguing to most visitors. The site would benefit from a general clean-up of the areas disturbed when the hotels were removed, but most of all by implementing the management plan that was prepared some years ago."

"Some of the natural pools have been closed to access after people stomped all over them."

"Extraction of groundwater affected water supplies for the springs. Tourist numbers in the archaeological zone can be high."

"The village at the entrance to the wells is an almost exclusively tourist-centered settlement. If good visitor management, waste management, and conservation monitoring are established, the site has potential."

Turkey: Istanbul historic areas

Score: 66

"Istanbul managed to preserve the quality of its old city, especially in the Sultanahmet area and the grand bazaar. The atmosphere is Turkish and the culture is secure as a crossroads of Asian and European cultures."

"Considerable work has been done to restore Hagia Sofia, including the restoration of Byzantine artwork. Public transit and pedestrian areas are well developed and user- friendly for tourists. The restoration of green spaces between Hagia Sofia and the Blue Mosque has been completed, making the area more pleasant."

"The contemporary urban development and tangible heritage makes multicultural Istanbul a unique destination."

"Suffers from congestion (which is increasing), traffic and transportation difficulties, and a lack of adequate signage, information, and tourist facilities."
