The city of Zurich is the largest city in Switzerland and the most important economic, scientific and social center of Switzerland. The city is located in the eastern Swiss Mittelland and on the Limmat river at the outlet of Lake Zurich. For years Zürich has been listed as one of the cities with the highest quality of life worldwide. Due to Switzerland’s largest railway station and the airport, the city is a continental transport hub and an international financial center thanks to the large international banks and insurance companies located here. Despite its comparatively low population of around 400,000, Zurich is one of the world’s leading cities. Thanks to its location on the shores of Lake Zurich, its well-preserved medieval old town and its many cultural attractions and nightlife, it is also a center of tourism.
