Seleukeia Pieria — A settlement in Syria also known as Seleucia by the Sea - Suedia
Seleukeia Pieria, also known in English as Seleucia by the Sea, and later named Suedia, was a Hellenistic town and the seaport of Antioch, the Seleucid capital. It was founded in ca. 300 BC by Seleucus I Nicator. The Macedonians called the landscape Pieria, after a district in their homeland that was also between the sea and a mountain range (the Olympus).

During Roman times, Seleucia's importance grew significantly, necessitating the enlargement of its harbours several times under Diocletian and Constantius. These harbours, called the "inner" and "outer" harbours, served from time to time the Roman navy. Most buildings and structures today date from the Roman period.

During Byzantine times the city went into a steady decline. The silting up of the city's harbours hastened this process. In the fifth century the fight to keep them open was finally given up. It was captured by the Sasanids around 540 AD. While it never recovered as a port-city again, Al-Walid ibn Abd al-Malik, Ummayad Caliph from 705-715, built a fortress in the city.
