Fraumunster, known as the women’s church, this church is considered one of Zurich’s four main churches. It was originally built in 853 by Louis the German for his daughter, Hildegarde, to have a place to worship. It was a convent for seven hundred years, and at one point the abbess was called to be ruler of the city. Today, the church is open for services and tours. Of special interest are the stained glass windows, some as tall as 9 meters (30 feet) high, as well as frescoes by the artist Paul Bodmer and the church clock tower.
