The city at the northern end of Lake Zurich began as a Roman settlement called Turicum. Zurich didn't become a free city until the 13th century, and shortly after that joined the newly established Swiss Confederation. The town's rise to prominence began during the era of Protestant reformer Ulrich Zwingli, who lived in Zurich from 1484 to 1531 and laid the foundation for the emergence of a Puritan-capitalistic culture. Today Zurich is one of the world's richest cities in terms of per capita income and its citizens enjoy the best quality of life in the world according to a survey conducted in 2007. Millionaires and billionaires from around the globe have established a residence in the city because of Swiss bank privacy laws and the country's low tax rate. Yet Zurich has much more to offer than secret bank accounts and low taxes: an attractive old town with chic cafés and bars, over 40 museums, and the famous Bahnhofsstrasse, one of the most elegant shopping avenues in Europe.
