Site archéologique de Saint-Pierre

The Archaeological Site of Saint-Pierre is a subterranean excavation beneath the cathedral in Geneva's Old Town, Switzerland, and it is a place many day visitors overlook while climbing the cathedral towers above. It is entered from the cathedral courtyard, the Cour de Saint-Pierre, and consists of walkways that pass beneath the choir and nave and reveal about 1,500 years of building history. Excavated layers show Roman and earlier remains, the foundations of an early Christian complex, floor mosaics, baptisteries and burial areas, together with the walls of successive churches that preceded the present Romanesque and Gothic cathedral. Panels, models and projections explain what is visible, and the lighting creates a calm, atmospheric route. Visitors should allow about 45 minutes, which is enough to follow the full path and read the main panels. The temperature underground is cool even in summer, so a light layer is helpful. Entry costs about CHF 8 for adults, and the site is open Tuesday to Sunday from 10:00AM to 5:00PM. Because the visit is entirely indoors, it suits rainy days and is usually quietest on weekday mornings. It forms a natural pair with the International Museum of the Reformation next door and the cathedral itself, and visitors who add it to an Old Town walk get a much deeper sense of how the city developed. The site rewards those who want to move beyond viewpoints and monuments and see the layers of history under their feet.
