Hierapolis

Fausset's Bible Dictionary

Colossians 4:13. Associated as the seat of a church with the neighbouring Colossae and Laodicea; on a height between the rivers Lycus and Meander, within a few miles of one another; the three churches were probably all founded by Epaphras. Now Pambouk Kalessi. Hot calcareous springs are near, which have deposited curious encrustations. There is a frozen cascade, the surface wavy, as of water suddenly petrified. A mephitic cavern, Plutonium, was in ancient times connected with the worship of Cybele, from from whence the city was designated Hierapolis, "the sacred city."
