Laodicea in Phrygia was an ancient city located in what is now western Turkey. It was founded in the 3rd century BCE and became a significant center for trade, culture, and finance. The city was known for its production of black wool and a famous medical school that specialized in eye treatments, contributing to its prosperity. The city is also mentioned in the Bible, specifically in the Book of Revelation, where it is described as one of the seven churches. Laodicea was known for its lukewarm water supply, which became a metaphor for the spiritual state of its inhabitants. Today, the ruins of Laodicea attract archaeologists and tourists alike.
