Among Zürich's most important landmarks are the city's principle churches, Fraumünster, Grossmünster and St. Peter's church:

Fraumünster, formerly the church for the noblewomen of Zürich donated by Louis the German (853), has foundation remains dating from the 9th to 11th century. The church is well known for its beautiful stained glass windows by Marc Chagall in the chancel (1970).

Grossmünster, with its unique twin spires, is probably Carolingian in origin and was the mother church of the Reformation in Switzerland under Ulrich Zwingli. The oldest parts are the crypt and remains of a Romanesque cloister with statuary from the 11th and 12th centuries. The chancel window was created by Augusto Giacometti.

The tower clock of St. Peter's church has Europe's largest clock dial with a diameter of 8.70 meters.
