Ras al-Bassit (Arabic: رأس البسيط‎), the classical Posidium or Posideium (Greek: Ποσιδήιον and Ποσείδιον, Posidḗion), is a small town in Syria named for a nearby cape. It has been occupied since at least the late Bronze Age and was a fortified port under Greek and Roman rule. Herodotus—although not later classical geographers—made it the northwestern point of Syria. Its beaches have a distinctive black sand and are a popular resort destination within Syria.
