Monaco, officially Principality of Monaco, French Principauté de Monaco, sovereign principality located along the Mediterranean Sea in the midst of the resort area of the Côte d’Azur (French Riviera). The city of Nice, France, lies 9 miles (15 km) to the west, the Italian border 5 miles (8 km) to the east. Monaco’s tiny territory occupies a set of densely clustered hills and a headland that looks southward over the Mediterranean. Many unusual features, however, have made Monaco among the most luxurious tourist resorts in the world and have given it a fame far exceeding its size.
