As one of the top financial hubs in the world and the wealthiest city in main Europe, Frankfurt is home to more than 117,000 millionaires, including 14 billionaires. Frankfurt stands out from other big German cities (Berlin, Hamburg) in terms of wealthy populations despite contributing less to the country's GDP.
Luxembourg is the wealthiest country in the European Union, per capita, and its citizens enjoy a high. It is a major center for large private banking, and its finance sector is the biggest contributor to its economy.
With almost 3.8 million inhabitants, the undisputed number 1 is the German capital of Berlin. Each of the city's districts has its own unique atmosphere, from chic to grung to hip to international. Of course, there are plenty of places of interest here, including the Brandenburg Gate and the Reichstag building.
This petite sliver of a country sits nestled in the mountains between Switzerland and Austria. Being so small it has no airport of its own, but access via road or rail from surrounding countries is a breeze. Despite this, it's Europe's least visited country.
