Monaco
The principality of Monaco sits on the stunning Côte d'Azur, surrounded on three sides by France and approximately 10 miles from Italy. The principality operates as a constitutional monarchy, with Prince Albert II as the current head of state. Famous as a tax haven, Monaco enjoys some particularly impressive statistics: it is the most densely populated country in the world, has the highest life expectancy (at almost 90 years) and the lowest unemployment (0%).
Monaco is officially the second smallest country in the world, losing out only to Vatican City. Possibly the city's most famous attraction is the annual Formula 1 Grand Prix, where Monaco's wealthiest residents and visitors watch the high-powered cars screaming through the city streets from the comfort of their super yachts moored in the harbour.
