The site became important especially after the capture of the region by the Seleucid king Antiochos III in 197 BC, serving as a port in Lycia during the Hellenistic and Roman periods too. It lived its heydays during the rule of Hadrian while the wheat imported by the Roman Empire from Egypt passed through this port. It had an important role also during the reign of Byzantine emperor Justinian I. But due to the Arabian raids, silting up of its harbor, and several earthquakes, Andriake lost its importance and abandoned around 8th century AD.
Amongst the ruins of the site we can mention churches, baths, 60 x 40 meters (200 x 130 feet) agora (market place), a cistern accessible by stairs, honoring monuments, 5th century synagogue, necropolis with sarcofagi, working stations for Murex production, and the Granarium which is a museum today.
The most impressive building at the site is the Granarium, which was built to store the wheat, grain, crops etc. It's a large stone building by 65 x 40 meters (215 x 130 feet) with a wooden roof, and divided into 8 sections. These huge grain silos built in Andriake and also in Patara shows us the trust of Rome to either cities and their strategic importance.
Another interesting section of the site was the working stations of "Murex". The Murex is a marine snail with a shell. These were processed in abundance at Andriake in order to get a purple color dye for the fabrics. The dye murex (Murex brandaris) of the Mediterranean was once a source of royal Tyrian purple.
