Grossmünster

The Grossmünster ("great minster") is a Romanesque-style Protestant 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 Zürich. 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 and Regula, Zürich's patron saints. The legend helps support a claim of seniority over the Fraumünster, which was founded by Louis the German, Charlemagne's grandson. Recent archaeological evidence confirms the presence of a Roman burial ground at the site.

Huldrych Zwingli initiated the Swiss-German Reformation in Switzerland from his pastoral office at the Grossmünster, starting in 1520. Zwingli won a series of debates presided over by the magistrate in 1523 which ultimately led local civil authorities to sanction the severance of the church from the papacy. The reforms initiated by Zwingli and continued by his successor, Heinrich Bullinger, account for the plain interior of the church. The iconoclastic reformers removed the organ and religious statuary in 1524. These changes, accompanied by abandonment of Lent, replacement of the Mass, disavowal of celibacy, eating meat on fast days, replacement of the lectionary with a seven-year New Testament cycle, a ban on church music, and other significant reforms make this church one of the most important sites in the history of the reformation and the birthplace of the Swiss-German reformation.
