Collégiale St-Laurent plays an important role in the social and religious life of this place. It's a wonderful place to enjoy a moment of contemplation during a packed travel itinerary.
When you've spent some time at this house of prayer in Salon-de-Provence, why not check out Zoo Barben, Nostradamus Museum, and Château de la Barben? They're not very far from Collégiale St-Laurent and also a hit with travelers.
