The architecture of the Saint Pierre Cathedral has undergone numerous changes over the course of history. The first construction phase dates back to 1160 and lasted almost a century. During the Reformation period, it served as a Protestant church from 1535.

Col de Croissette. What a beautiful tour. A long climb with percentages up to 18% brings you to the plateau of the mountain. There with rolling roads and paths towards the west to enter the descent and via the North back to Geneva.

The secrets of ancient Geneva, Cathédrale Saint-Pierre de Genève A gripping testimony to the early Christian era, an important period in the development of Christianity. Beneath St. Peter's Cathedral lie the remains of the churches that preceded it, the oldest of which dates from the late 4th century: but there are also pre-Christian traces of the settlement on this hill: wells, wheat processing area, a building probably used for cult purposes, Allobroges' tomb. Several rooms have been specially set up and present one of the most important archaeological sites north of the Alps using modern museographic techniques. Free audio guide available in French, German, English, Italian, Spanish and Japanese.
