This is one for the enthusiastic amateur archaeologists. The scanty remains of the once great Phrygian city of Colossae (also known as Kolossai) lie in the Lykos Valley, near the Lykos River, 20 kilometers east of Denizli. Its great age was during the Hellenistic period.
By the time the Romans had taken control over the region, it was increasingly overshadowed in importance by the cities of Laodikeia and Hierapolis, and the town eventually lost its prominence.
