Hierapolis: Sacred city, a city of Phrygia, where was a Christian church under the
care of Epaphras
(Colossians 4:12,13) This church was founded at the same
time as that of Colosse. It 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.
