The Cathédrale St-Pierre is Geneva’s wonderful cathedral that was founded in the 11th century, It is especially Gothic with an 18th century neo-classical façade and is famous for having been where the Protestant John Calvin preached between 1536 and 1564. During the summer visitors can enjoy free organ and carillon concerts at the church. The church itself is pretty enough if you like gothic architecture however the highlight are the cathedral tower. For 4 francs you can access these towers which wind up through 76 steps to the cathedral attic. Another 40 steps take you to either the northern or southern towers of the church from where you get a stunning panoramic view of Lake Geneva. The basement of the cathedral offers you a collection of 4th century mosaics and the tomb of an Allobrogian chieftain whose history is not really known.
