The Fraumünster is famed for its incredibly colorful stained-glass windows, designed by Marc Chagall. The church was, however, built a long time before the window was created and was a present from Ludwig des Deutschen (literally, "Ludwig of the Germans") to his daughter, who was the first Abbess of the ladies' chapter. Not only did she rule over extensive territory, she also had a private mint; however, only the cloister and church with its romantic choir and Gothic nave were spared the wrath of the Reformation. The tower on the left-hand side of the building was erected in 1732 and presents a refreshing antithesis to the nearby twin towers of the Grossmünster.
