Pierre et Lumière, Museum in Saint-Hilaire-Saint-Florent, Saumur, France
Pierre et Lumière is a museum set inside an underground tuffeau quarry in Saint-Hilaire-Saint-Florent, near Saumur in the Loire Valley, France. Visitors walk through a network of tunnels and galleries where sculptor Philippe Cormand carved about twenty reproductions of famous Loire Valley monuments directly into the stone walls.
The site was founded by Yann Bouchard, a local enthusiast who wanted to show the beauty of tuffeau, the soft white stone used throughout the region for centuries. Philippe Cormand, a Breton sculptor who had won several carving competitions, spent three years cutting the works into the rock.
The name Pierre et Lumière means "stone and light" in French, which reflects what visitors actually experience inside: carved stone brought to life by light. Since 2026, a projection show inspired by the medieval manuscript "Très Riches Heures du Duc de Berry" lights up the sculptures with seasonal colors.
The site is easy to reach by car along the Route de Gennes in Saumur, with parking available nearby for both private vehicles and buses. It is accessible for wheelchair users accompanied by a helper, and facilities on site include restrooms, a small shop, and a picnic area.
The underground network of tunnels that surrounds the gallery is said to extend for around 200 kilometers, far beyond the section open to visitors. The soft tuffeau stone carved for the sculptures is the same material used to build many of the real châteaux and churches found across the Loire Valley.
