Olympos is a valley at the south coast of Turkey, 90 km southwest of Antalya city near the Town of Kemer.

The city was founded in the Hellenistic period, sharing its name with nearby Mount Olympos. Its coins date back to the 2nd century BC. The city became one of the six leading cities of the Lycian federation. In the 1st century BC, Olympos was invaded and settled by Cilician pirates. This ended in 78 BC, when the Roman commander Servilius Isaurieus added the city to the Roman Empire. The emperor Hadrian visited the city after which it took the name of Hadrianopolis for a period, in his honour.

During the Ottoman area the city lost its character and because of floods, the people left the area. South of the port, a part of the caveas and the entrance of the theatre still remains. The theatre was used as an outdoor Orthodox basilica during the Byzantine era. There are remains of the Roman Bathhouse and, on the south bank of the river, the remains of a Byzantine Church. In the south of the river is the main necropolis with more than 200 inscribed tombs.2 sarcophagi, named Port Monumental Tombs, have been unearthed during recent excavations. Today the area is a favourite tourist place, with its nice beach of great beauty and pensions, small guest houses, restaurants, yörük style bungalows and the special tree houses.

In the Middle Ages, Venetians, Genoese and Rhodians built two fortresses along the coast, but by the 15th century Olympos had been abandoned. Today the site attracts tourists, not only for the artifacts that can still be found (though fragmentary and widely scattered), but also for its scenic landscapes supporting wild grapevines, flowering oleander, bay trees, figs and pines.
