Hierapolis

Meaning: sacred city

a city of Phrygia, where was a Christian church under the care of Epaphras (Col. 4:12, 13)

The church at this city was founded at the same time as that of Colosse.

The city now bears the name of Pambuk-Kalek, i.e., “Cotton Castle”, from the white appearance of the cliffs at the base of which the ruins are found.
