Spectacular white travertines and well-preserved ancient city
Pamukkale, as its name implies (Cotton Castle), is an unreal landscape made up of mineral forests, petrified waterfalls and series of terraced basins. At the end of 2nd century BC, the dynasty of Attalids, the kings of Pergamon, established the thermal spa of Hierapolis. The ruins of
baths, temples and other monuments can be seen at Pamukkale. Hierapolis is in exceptional example of Greco-Roman thermal installation established on an extraordinary natural site. The therapeutic virtues of waters were exploited at the various thermal installations. Pamukkale-
Hierapolis site is largely intact and includes all attributes to express its universal value. (UNESCO World Heritage Site, 1988)

Hierapolis was an ancient Greek city located on hot springs in classical Phrygia in southwestern Anatolia. Its ruins are adjacent to modern Pamukkale in Turkey and currently comprise an archaeological museum designated as a UNESCO World Heritage Site.

The hot springs have been used as a spa since the 2nd century BC, with many patrons retiring or dying there. The large necropolis is filled with sarcophagi, most famously that of Marcus Aurelius Ammianos, which bears a relief depicting the earliest known example of a crank and rod mechanism.Part of the archeological site of Hierapolis. The great baths were constructed with huge stone blocks without the use of cement and consisted of various closed or open sections linked together. There are deep niches in the inner section, including the bath, library, and gymnasium.

Frontinus Gate

This is the monumental entrance to the Roman city and leads onto the large plateia, 14 m wide, which crosses the whole settlement, exiting a gate at the opposite side, to connect with the road that goes to Laodicea on the Lykos and then Colossae. It is worth admiring the well preserved structure with three openings, in carefully squared travertine blocks, with elegant arches decorated with a simple cornice moulding, flanked by two round towers that recall Hellenistic city Gates such as that of the Pamphilian city of Perge, near Antalya
