Grossmünster (“large cathedral” in German) is a Romanesque ex-cathedral situated in the heart of Zürich, Switzerland, which was built over the course of the 11th and 13th centuries CE. According to legend, the Holy Roman Emperor Charlemagne founded Grossmünster around c. 810 CE to house the bones and relics of the early Christian martyrs St. Felix, St. Regula, and St. Exuperantius who were believed to have fled to Zürich and died in city during the 3rd century CE. Grossmünster is Zürich's most recognizable and famous landmark by virtue of its iconic twin towers, and it retains a place of prominence in Protestant Christianity due to its role in the Protestant Swiss Reformation, which began at the direction of Ulrich Zwingli in 1519-1520 CE. Along with Fraumunster, Predigerkirche, and St. Peterskirche, Grossmünster is one of the oldest and largest churches in Zürich. Its triple-aisled crypt is also the largest in Switzerland.
