The ancient ruins of Amos are accessible from the Asarcık hill, northwest of Kumlubuk bay. Amos dates back to the Hellenistic period, and is composed of a hillside amphitheatre, a temple and statue pedestals. Surrounded by ramparts dating back to the same time, this amphitheatre is in good condition, with its seating area, side walls and stage with three chambers. Excavations in 1948 by Prof. Bean revealed four inscriptions, which mentioned three rental contracts, thought to date back to around 200BC.
