Some ancient sites were built near the river banks but there is the fact that the rivers bring alluviums to the sea. Seleucia Priera was one of those sites.

Selecuia Priera was one of the important port cities in Mediterranean coasts in Roman period. Also it was a naval port in 4th century BC. But it lost its importance when the gulf was filled with alluviums. So it became an inner land site. It was a famous site with various buildings such as city walls and temples.

It is located in southern region of Turkey. It is in border of Hatay province.
