Ligurian Sea Ligurian Sea The Ligurian Sea (; ) is an arm of the Mediterranean Sea, between the Italian Riviera (Liguria) and the island of Corsica. The sea is theorized to be named after the ancient Ligures people. The sea borders Italy as far as its border with France, and the French island of Corsica. In the east the sea borders the Tyrrhenian Sea, while in the west it borders the Mediterranean Sea proper. Genoa is the most prominent city in the area. The northwest coast is noted for its scenic beauty and favourable climate. The Gulf of Genoa is its northernmost

A line joining Cape Corse (Cape Grosso, 9°23′E) the Northern point of Corsica to the frontier between France and Italy (7°31′E). "On the Southeast."
