This was a spa resort founded in 190 BCE by Eumenes II of Pergamum. Of particular importance is the Necropolis, which holds some 1,000 tombs ranging from majestic to very small and simple from various time periods.
There are (were) two bath complexes, and a theater with most of its stage standing! As far as records can indicate, this was a center of healing where people came to seek the curative powers of the waters. Hieropolis was destroyed twice by earthquakes, after which it was not rebuilt. We did not see the Plutonium, which is situated behind the Pamukkale Hotel, and was dedicated to the underworld God, Pluto.
