Laodicea on the Lycus (Denizli)

In the Roman Empire, Laodicea on the Lycus, which was established in the third century BC, served as a significant commercial and trade hub. It was also known for its medical school and the production of a black woolen cloth called "Laodicean black." The city was mentioned in the New Testament book of Revelation as one of the Seven Churches of Asia, and it played an important role in early Christianity. After being completely destroyed by an earthquake in the seventh century AD, Laodicea was abandoned. Today, visitors can see the ruins of the city, including the impressive stadium, theater, and ancient water pipes.
