Grossmünster

According to legend, Charlemagne discovered the graves of the city's martyrs Felix and Regula and had a church build as a choristers' cloister on the spot. Construction work on the present building began around 1100. In the first half of the 16th century the Grossmünster was the starting point of the Swiss-German Reformation led by Huldrych Zwingli and Heinrich Bullinger. The theological college then annexed to the cloister became the germinal cell of what is now the University of Zürich.
