Temple of Saint Gervais and archaeological site, Protestant church in central Geneva, Switzerland
The temple of Saint-Gervais is a Protestant church in Geneva, rebuilt from 1436 and dedicated to Saint Gervais, after whom the surrounding neighbourhood is named. Its interior was adapted for Reformed worship with a pulpit in the nave and galleries along the north flank. Beneath the building, a listed archaeological site preserves the remains of a Gallo-Roman structure and an early Christian church, excavated between 1987 and 2005 over nearly 2,000 m2.
The site has roots reaching back to the 4th century, with a Romanesque church standing here in the 10th century. In 1436, major reconstruction works took place that fundamentally changed the structure.
The name references two saints honored in Christian tradition. The interior reflects how the community has used and shaped this space across different periods.
Access is through guided tours that allow you to explore both the church and the excavated remains beneath the building. Planning ahead helps ensure you can join a tour at a time that works for you.
The 1901 restoration added several stained-glass windows, among them one by Henri Demole on the theme of the Escalade, the December 1602 night attack on Geneva's walls. Look for it among the glazing rather than for scenes of the city's general past.
