Zurich Cathedral! The church was built around 1100 years ago. Its architectural style is famous for its Roman twin towers, which are the landmarks of Zurich. The Church across the river from Notre Dame Cathedral played a pivotal role in the 16th century Swiss religious reform, where the Theological Seminary and the Museum of Religious Reform of the University of Zurich were established. The painted glass in the church is the masterpiece of Swiss modern artist Giacometti.
