The Cathedral of Notre Dame of Zurich is a Church of the Reformed Church in Zurich. Founded in 853, the King donated the Benedictine nunnery, whose land was exempted from taxes and directly managed by it. In 1045, King Henry III authorized the nuns to open markets, collect tolls and forge money, which enabled the nuns to actually establish city managers and appoint mayors by the nuns. However, the power of the monastery gradually diminished in the 14th century, and independent mayors began to emerge that were not dominated by the monastery. Zurich Cathedral, Notre Dame Cathedral and St. Peter Cathedral are the three main churches in Zurich. The church looks beautiful across the river from Zurich Cathedral.
