Zurich is the capital of Zurich, the largest city in Switzerland, the richest city in Europe, and an important financial center in Western Europe. There are more than 120 banks, more than half of which are foreign banks, so they enjoy the title of "European millionaire city". On both sides of Silpolt Avenue, there are Lindbergh Bank and the Stock Exchange, from which funds are mobilized annually, reaching an unpredictable astronomical figure.
