Rising high above Geneva's cobbled Old Town, St-Pierre Cathedral fuses Romanesque, Gothic and neoclassical styles. Climb North Tower for far-reaching views over Lake Geneva to Mont Blanc. The cathedral's archaeological site hides a 4th-century baptistery and intricate 5th-century mosaics.
Built between 1160 and 1232, it retains an austere atmosphere - John Calvin once preached here. The real excitement is underground, where you'll find one of Europe's largest subterranean archaeological sites and discover the evolution of the church over centuries (audio-guides recommended).
St-Pierre could tell many a tale if stones could speak. Its troubled history includes the Reformation, when extremists desecrated its relics.
