Pamukkale–Hierapolis went onto the UNESCO World Heritage List in 1988 as entry 485, under three criteria and in the mixed category — natural and cultural at once. That double listing describes the place better than any sentence about it: white travertine terraces built up by calcium-bearing water running off the southern slopes of Çaldağı, and, standing among them, an ancient city. The directorate puts the number of visitors at around two million a year.
The terraces form where the thermal water meets the air and leaves its minerals behind, building up in steps like a waterfall stopped mid-fall, with pools held on the flatter ledges. The formation took thousands of years and damages easily, so only certain stretches are open to walk on and to bathe in. The water's reputation for relieving a range of ailments is not a modern claim either: it is the reason the city is where it is, and people came from across Anatolia to it for centuries.
The ministry records that the city was probably founded in the second century BC by Eumenes II of Pergamon, and that the name is thought to come from Heira, wife of Telephos, the founder of Pergamon. Older sources knew Hierapolis for metalwork, stone carving and woven cloth. Under Constantine the Great it was the capital of the province of Phrygia, and in the Byzantine period the seat of a bishop. It worked throughout as a thermal centre, which is what most of the surviving building was for.
What survives stands in unusual completeness. The Roman bath, heavily used when this was a spa city, now houses the archaeological museum, where the statues and other finds from the excavations here and in the surrounding country are displayed. The theatre, the temples, the monumental fountains, the agora, the gymnasium and the tombs are all intact enough to give the sense of walking through a city rather than a ruin field. Among them is the place the Romans took for an entrance to the underworld.
The site is eighteen kilometres north of central Denizli and minibuses run to it from the Denizli bus station. Those who want to stay longer can use the thermal establishments near the ancient city, which offer lodging along with massage, thermal water and mud baths.
