Grossmünster

The Grossmünster (; "great minster") is a Romanesque-style Swiss Reformed Church in Zurich, Switzerland. It is one of the four major churches in the city (the others being the Fraumünster, Predigerkirche, and St. Peterskirche). Its congregation forms part of the Evangelical Reformed Church of the Canton of Zurich. The core of the present building, near the banks of the Limmat, was constructed on the site of a Carolingian church, which was, according to legend, originally commissioned by Charlemagne. Construction of the present structure commenced around 1100 and it was inaugurated around 1220.

The Grossmünster was a monastery church, vying for precedence with the Fraumünster, across the Limmat, throughout the Middle Ages. According to legend, the Grossmünster was founded by Charlemagne, whose horse fell to its knees over the tombs of Felix, Regula, and Exuperantius, Zurich’s patron saints. The legend helps support a claim of seniority over the Fraumünster, which was founded by Louis the German, Charlemagne's grandson. Archaeological evidence confirms the presence of a Roman burial ground at the site.
