The Varius Baths of Ephesus were firstly built during the Hellenistic era and then enlarged during the Roman and the Byzantine times. Made of marble they consisted of three sections: the frigidarium with cold water, the tepidarium with warm water and the caldarium with hot water. There were also resting, sitting and reading rooms which were built in the 2nd century AD yet restored and new rooms added later. The mosaic corridor (40 m long), which has survived nowadays, dates back to the 5th century AD. [ephesus.ws]
