Behind two Lycian sarcophagi, you see the ruins of a Byzantine Church, proof that ancient Sidyma continued well into the first centuries AD. Due to the early Christian zealots which had the explicit approval of "Saint" Augustine and other influential bishops, about 95% of the Latin literature (plays & scientific discoveries) got destroyed in the Roman Empire. Therefore, there is only one mention of ancient Sidyma which survived to this day.
In the fields to your left, in the far distance, stands a well-built monumental structure identified as a Roman Heroon.
A Heroon is a shrine dedicated to an ancient Greek or Roman hero and used for the commemoration or cult worship of the hero. They were often erected over his or her supposed tomb or cenotaph. They were erected from the time of archaic Greece to the Augustan Roman period, and as far afield as Ai-Khanoum in Afghanistan.
