The remnants of Roman Diocaesarea sit within the village of Uzuncaburç, 30km northeast of Silifke. Originally this was the Hellenistic city of Olba, home to a zealous cult that worshipped Zeus Olbius.
The impressive Temple of Zeus Olbius , with two dozen erect columns, lies to the left of the colonnaded street . Beside the temple are various sarcophagi bearing reliefs. Important Roman structures include a nymphaeum (2nd century AD), an arched city gate , and the Temple of Tyche (1st century AD).
Just before the entrance to the main site is a small Roman theatre . To view a Hellenistic structure built before the Romans sacked Olba, head north through the village, where you'll pass a massive, five-storey watch tower with a Roman road behind it. Another 600m down into the valley leads to a long, roadside necropolis of rock-cut tombs and more sarcophagi.
On the road to Uzuncaburç some 8km out of Silifke at Demircili – ancient Imbriogon – you'll pass several superb examples of Roman monumental tombs that resemble houses.
