Kotor is a coastal city in Montenegro, secluded in the southern end of the Gulf of Kotor. The Bay is one of the most indented parts of the Adriatic Sea and is sometimes called the southern-most fjord in Europe. The city has a population of about 14,510. This picturesque old Mediterranean city is surrounded by an impressive city wall built by the Republic of Venice; Venetian influence remains predominant in the city’s architecture. High overhead is the old fortress that guarded the city, a popular tourist climb of many hundreds of steps. Together with the nearly overhanging limestone cliffs of Orjen and Lovćen, Kotor and its surrounding area form an impressive scenic site. Many visitors come by cruise ship attracted both by the natural beauty of the Bay and by the quaint old town of Kotor itself. The city is a World Heritage Site.
