St. Peter

The Fraumünster Zurich, established in 853, is one of the four Reformed churches of the Old Town and one of the city's landmarks. The former Fraumünster Monastery, destroyed in the 19th century, was a Benedictine monastery.

The Wasserkirche was originally located on a small island in the Limmat, but today the church is attached to the right bank. Before the Reformation, the Wasserkirche played an important role in the veneration of the Zurich saints Felix and Regula, as it was the place of their execution. The crypt of the first Wasserkirche, built in the 10th century, was a low church around a rock which was venerated as the place of execution of Felix and Regula. From 1940 excavations were carried out in the crypt for the first time. The crypt of the Wasserkirche has been open to the public since 1988.

The Grossmünster, built between 1100 and 1220, is a protestant reformed church in Zurich's old town. The first part of the Grossmünster is believed to have been built by Charlemagne, who discovered the tombs of Saints Felix and Regula, two martyrs of Christianity, around the 7th century. The Protestant Reformation in Switzerland led by Ulrich Zwingli began in the Grossmünster, where he preached from 1519 onwards as a priest. The twin towers of the church, with their neo-Gothic domes, are the symbol of the town.
