The Fraumünster (; lit. in ) is a church in Zürich which was built on the remains of a former abbey for aristocratic women which was founded in 853 by Louis the German for his daughter Hildegard. He endowed the Benedictine convent with the lands of Zürich, Uri, and the Albis forest, and granted the convent immunity, placing it under his direct authority. Today, it belongs to the Evangelical Reformed Church of the canton of Zürich and is one of the four main churches of Zürich, the others being the Grossmünster, Prediger and St. Peter's churches. History In 1045, King Henry III granted the convent the right to hold markets, collect tolls, and mint coins, and thus effectively made the abbess the ruler of the city. Emperor Frederick II granted the abbey Reichsunmittelbarkeit in 1218, thus making it territorially independent of all authority save that of the Emperor himself, and increasing the political power of the abbess. The abbess assigned the mayor, and she frequently delegated the minting of coins to citizens of the city. A famous abbess during this time of great power was Elisabeth of Wetzikon. However, the political power of the convent slowly waned in the fourteenth century, beginning with the establishment of the Zunftordnung (guild laws) in 1336 by Rudolf Brun, who also became the first independent mayor, i.e. not assigned by the abbess. The abbey was dissolved on 30 November 1524 in the course of the reformation of Huldrych Zwingli, supported by the last abbess, Katharina von Zimmern. The monastery buildings were destroyed in 1898 to make room for the new Stadthaus. The church building today serves as the parish church for one of the city's 34 reformed parishes. Münsterhof, historically the main square and marketplace of the medieval city, is named for the abbey. Gesellschaft zu Fraumünster cultivates the traditions of the former nunnery convent. Chagall windows The choir of the abbey includes 5 large stained glass windows designed by artist Marc Chagall and installed in 1970. Each of the 5 has a dominant color and depicts a Biblical story. From left (northern wall) to right, the 5 works are: Prophets, depicting Elijah's ascent to heaven Jacob, displaying his combat, and dreams of heaven Christ, illustrating various scenes of Christ's life Zion, showing an angel trumpeting the end of the world Law, with Moses looking down upon the suffering of his people Equally impressive
