Notre Dame Cathedral of Lausanne, standing high in the center of the old city, is the largest church in Switzerland, with a magnificent Gothic appearance. The church has painted glass windows up to 9 meters in diameter, which is quite gorgeous. It still follows the tradition of night watchmen. In addition to visiting church buildings, you can also climb the Bell Tower through more than 200 steps, overlooking the beautiful scenery of Lausanne and Lake Lamont.
