Seleucia Pieria

Seleucia in Pieria (Greek Σελεύκεια ἐν Πιερίᾳ), also known in English as Seleucia by the Sea, and later named Suedia, was a Hellenistic town, the seaport of Antioch ad Orontes (Syria Prima), the Seleucid capital, modern Antakya (Turkey). The city was built slightly to the north of the estuary of the river Orontes, between small rivers on the western slopes of the Coryphaeus, one of the southern summits of the Amanus Mountains.

According to Pausanias and Malalas, there was a previous city here named Palaeopolis ("Old City"). At present, it is located at the seaside village of Çevlik

near the town of Samandağ in the Hatay Province of Turkey. Seleucia, Apamea, Laodicea, and Antioch formed the Syrian tetrapolis.
