Second, geographical location.

Luxembourg, with its changeable terrain, is at the crossroads of Germany and France in history. It has always been an important military fortress in Western Europe and is known as Gibraltar in the north. Luxembourg is a highly developed capitalist country, the most important private banking center in the euro zone and the second largest investment trust center in the world after the United States. Per capita income ranks among the highest in the world, with an average life expectancy of 80 years. It is one of the safest cities with the highest living standard in the world.
