Monaco

Monaco, a principality on the French Riviera, has been ruled by the Grimaldi family since 1297, making it the world's oldest dynastic sovereignty. The world's most densely populated sovereign state, its economy rests on tourism, gambling (casino from 1863), and financial services. Monaco uses the euro and is known for the Formula One Monaco Grand Prix and its ultra-wealthy resident community.
