Laodicea on the Lycus was an ancient city in Asia Minor, situated on a hill above the river Lycus. It was located in the Hellenistic regions of Caria and Lydia, which later became the Roman Province of Phrygia Pacatiana, close to the modern city of Denizli in Turkey. Laodicea was built on the site of an earlier pre-Hellenistic settlement, and was founded by Antiochus II Theos, the king of the Seleucid Empire from 261 to 253 BC, in honour of his wife Laodice, together with several other cities of the same name. Laodicea became a wealthy city, and was later controlled by the Roman and Byzantine empires. The city had a large Jewish population, dating from the time of Antiochus the Great, who transported 2000 Jewish families there from Babylonia. It also became an early seat of Christianity with a bishopric. The Epistle to the Colossians mentions Laodicea as one of the communities of concern for Paul the Apostle. The city was destroyed in an earthquake in around AD 60, and subsequently rebuilt. It was eventually destroyed during the invasions of the Turks and Mongols during the second millennium, and is now a ruin. This photograph taken in 2020 shows the remains of a colonnaded Laodicean street.Photograph credit: Alexander Savin
