The elegant, Gothic forms of the Predigerkirche are only visible from one side, as on the other side it is partly integrated into the city’s central library. First mentioned in 1231, the preacher’s church was run by monks of the Dominican order, who put an emphasis on spreading the word. Zwingli’s Reformation meant the monks were kicked out, and the Predigerchurch became protestant. Nowadays they’re a bit more tolerant, they actually employ a Catholic priest and celebrate joint masses with Muslims or Buddhists. The church is open all day as a place of quiet, you can also always talk to a counsellor if you wish.
