Catedral de São Pedro (Cathédrale Saint-Pierre de Genève)

Cathédrale Saint-Pierre de Genève
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.
The strenuous climb up the 157 steps to the top of the tower is rewarded with a breathtaking 360° panoramic view of the city and the lake. The church also has the highest number of Romanesque and Gothic capitals in Switzerland. Beneath the cathedral is the archaeological excavation site, where remains from antiquity can be seen.

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.

Geneva's main church, St. Peter's Cathedral, is a peculiar looking building. Architecturally, different styles meet here: construction in the Romanesque style began in 1160, and the cathedral was completed a hundred years later in the Gothic style. In the 18th century, a somewhat incongruous classical column portico was added. The ornate stained glass windows inside are particularly worth seeing and the organ is also worth a closer look.
