Laodicea on the Lycus was an ancient city built on the river Lycus . It was located in the Hellenistic regions of Caria and Lydia, which later became the Roman Province of Phrygia Pacatiana. It is now situated near the modern city of Denizli.It contained one of the Seven churches of Asia mentioned in the Book of Revelation.HistoryLaodicea is situated on the long spur of a hill between the narrow valleys of the small rivers Asopus and Caprus, which discharge their waters into the Lycus. The town was originally called Diospolis, "City of Zeus", and afterwards Rhodas. Laodicea, the building of which is ascribed to Antiochus II Theos in 261-253 BC in honor of his wife Laodice, was probably founded on the site of the older town. It was approximately 17km west of Colossae, and 10km south of Hierapolis. It was approximately 160km east of Ephesus and, according to Strabo, it was on a major road. It was in Phrygia, although some ancient authors place Laodicea in differing provincial territories – not surprising because the precise limits of these territories were both ill-defined and inconstant; for example, Ptolemy and Philostratus call it a town of Caria, while Stephanus of Byzantium describes it as belonging to Lydia.
