Zürich or Zurich is the largest city in Switzerland and the capital of the canton of Zürich. It is located in north-central Switzerland at the northwestern tip of Lake Zürich. The municipality has approximately 400,028 inhabitants, and the Zurich metropolitan area 1.83 million. Zürich is a hub for railways, roads, and air traffic. Both Zürich Airport and railway station are the largest and busiest in the country.
Permanently settled for around 2000 years, the history of Zürich goes back to its founding by the Romans, who, in 15 BC, called it Turicum. However, early settlements have been found dating back more than 6400 years ago. During the Middle Ages Zürich gained the independent and privileged status of imperial immediacy and, in 1519, became a primary centre of the Protestant Reformation in Europe under the leadership of Ulrich Zwingli.
Zürich is a leading global city and among the world's largest financial centres. The city is home to a large number of financial institutions and banking giants. Most of Switzerland's research and development centres are concentrated in Zürich and the low tax rates attract overseas companies to set up their headquarters there.
Monocle's 2012 "Quality of Life Survey" ranked Zürich first on a list of the top 25 cities in the world "to make a base within". According to several surveys from 2006 to 2008, Zürich was named the city with the best quality of life in the world as well as the wealthiest city in Europe.
Many museums and art galleries can be found in the city, including the Swiss National Museum and the Kunsthaus. Schauspielhaus Zürich is one of the most important theatres in the German-speaking world.
