Beneath Saumur, a miniature Loire unfurls in stone: some twenty finely carved monuments set into a labyrinth of troglodyte galleries that the site presents as the equivalent of 200 kilometres of pathways. Pierre et Lumière is a celebration of regional craft and memory—an underground park cut from tuffeau where the ideas of Yann Bouchard and the sculptural talent of Philippe Cormand meet to give the valley’s architecture a subterranean echo.

THE ROUTE

A troglodyte promenade mapped in stone

The experience unfolds along an intricate network presented as the equivalent of 200 km of troglodyte passages beneath Saumur, offering a continuous subterranean stroll through scaled representations of Loire landmarks.

THE ART

Sculptures hewn from tuffeau

About twenty sculptures depict the region’s most iconic monuments, all carved directly in the local tuffeau—a material intimately tied to the caves and cellars of the Loire.

THE MAKERS

A meeting of two passions

Pierre et Lumière is the result of a local visionary who wished to display Loire monuments in their building material and a prize‑winning sculptor who realized the idea—Yann Bouchard and Philippe Cormand working together to give the troglodyte site its character.
