The Fraumünster Church in Zurich is 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 Zurich, Uri, and the Albis forest, and granted the convent immunity, placing it under his direct authority.
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, the town square in front of Fraumünster, is named after the former abbey. Gesellschaft zu Fraumünster cultivates the traditions of the former nunnery convent.
Since the last renovation in 1900, the crypt under the choir of the Fraumünster abbey was sealed, and has made public since 19 June 2016. The oldest part of the church preserved the abbey's Holy Relics until the Reformation in Zürich banned the Roman Catholic adoration of saints. The foundations of the crypt date back to the 9th century when the abbey was founded. The crypt also comprises an exhibition on the history of the Reformation in Zürich, on the architecture and local history, assisted by a multimedia information system that illustrates the foundation fragments of the crypt, and how the church was rebuilt from the original Romanesque construction phase to its present Gothic appearance, on occasion of its establishment guided by Dölf Wild, the archaeologist in charge.
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 Christian story.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
