Syia and Lissos were capacious and safe harbours of Elyros.
The name Syia derives probably from the word “sys (σῦς), i.e. hog.
Therefore, Syia is the “hog-city”.
There might have been forests of oaks and hollies, which is the basic food of pigs.
Syia flourished in the Roman and the 1st Byzantine period.
There are Roman ruins and three large Palaiochristian Basilicas.
Syia had set up monetary union with Yrtakina, Elyros, Lissos, and Tarra.
The city also participated in the Koinon the Oreians.
It seems that the Saracens destroyed the city.
In Syia, there are relics of ancient buildings, walls, hollowed tombs, and the foundations of Roman houses.
In the location of the ancient Syia, today lies the village of Sougia.
