Bern’s 15th-century Gothic cathedral boasts Switzerland’s loftiest spire (100m); climb the 344-step spiral staircase for vertiginous views. Coming down, stop by the Upper Bells (1356), rung at 11am, noon and 3pm daily, and the three 10-tonne Lower Bells (Switzerland’s largest). Don’t miss the main portal's Last Judgement, which portrays Bern’s mayor going to heaven, while his Zürich counterpart is shown into hell. Afterwards wander through the adjacent Münsterplattform, a bijou clifftop park with a sunny pavilion cafe.
