The old Mediterranean port of Kotor is surrounded by fortifications built during the Venetian period. It is located on the Bay of Kotor (Boka Kotorska), one of the most indented parts of the Adriatic Sea. Some have called it the southernmost fjord in Europe, but it is a ria, a submerged river canyon. Together with the nearly overhanging limestone cliffs of Orjen and Lovcen, Kotor and its surrounding area form an impressive landscape.
