Adriatic SeaThe Adriatic Sea (ˌeɪdriˈætᵻk) is a body of water separating the Italian Peninsula from the Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along the Croatian part of its eastern coast.
Vis (town)Vis (Lissa) is a town on the eponymous island in the Adriatic Sea in southern Croatia. Its population was 1,934 as of 2011. The town is the seat of the eponymous Vis municipality, one of the island's two municipalities (the other being Komiža). Both belong administratively to Split-Dalmatia County. Vis, on the Illyrian coast, was established in the 4th century BCE as an Ancient Greek polis Issa, a colony of Syracuse, Sicily (which in turn was a colony of Corinth).
