Cathédrale de St-Pierre
From Roman mosaics in the foundations to the neoclassical columns of its facade, the Cathédrale de Saint-Pierre is not only Geneva’s main house of worship, it is also a fascinating time capsule of the different influences that have dominated the city over the centuries. Depending on how you approach it, you could be forgiven for thinking the cathedral is actually a group of smaller buildings huddled together, as successive building programs – most notably Romanesque and Gothic – never completely wiped out previous traces.
Saint-Pierre is associated above all with the Protestant reformer John Calvin, who preached here in the 16th century; his rather uncomfortable looking wooden chair is still on display. And if you’re feeling energetic, just nearby is the entrance to the cathedral’s north tower, which will reward your 157-step climb with one of the best views of Geneva.
The cathedral, in the center of the Old Town, can be visited free of charge, though there is a small fee for climbing the tower. There is also an admission charge for the archaeological site in the cathedral’s foundations, featuring late Roman mosaics and the remnants of Geneva’s oldest Christian shrines, which is reached by a separate entrance.
