You don't need to have a strong religious faith to appreciate the calming atmosphere of Grasse Cathedral. Check when the next mass starts or when you can go for a wander through.
Located in Grasse, this principal church is well worth including on your itinerary. But you'll find tons more to discover in the area. International Perfume Museum, Museum and Parfumerie Fragonard, and Opio Valbonne Golf Club are within close reach of Grasse Cathedral.
