The Grossmünster is one of Zurich's most iconic landmarks and a significant historical and architectural monument. It features twin towers, each approximately 58 meters (190 feet) tall, which are one of the most recognizable features of Zurich's skyline. The stained glass windows by Sigmar Polke, the Romanesque crypt, choir windows by Augusto Giacometti, bronze doors by Otto Münch and the cloister Reformation Museum are just some of the highlights see here.
