The Caves of Saumur
Treasures hidden in the tuffeau stone
📱 1 to 10 phones · 1 team per phone · Independent codes
Saumur is a troglodyte city. Beneath its streets, kilometers of galleries carved in tuffeau stone hide treasures from the Wars of Religion. The Cadre Noir, the elite cavalry school, guards a secret known only to the finest riders.
Beneath the white city, a stone labyrinth has kept its secrets for five centuries
The Château de Saumur, perched on its white tuffeau promontory, looks like a fairytale castle — and that is exactly how the Limbourg brothers painted it in the Très Riches Heures of the Duke of Berry in the 15th century. But beneath this surface elegance, Saumur hides an underground world. Hundreds of troglodyte caves carved in limestone extend beneath the city, witnesses to centuries of trade, wars and secrets.

« "War is the only art where horse and man become one." »— — Traditional motto of the Cadre Noir of Saumur
Saumur — the white city with a thousand caves
Saumur owes its existence to tuffeau, the soft white limestone that forms the subsoil of the entire Loire Valley. Since Gallo-Roman times, it has been quarried to build châteaux, churches and houses — leaving behind a network of underground galleries stretching for dozens of kilometers. These caves became wine cellars, mushroom farms, and during the Wars of Religion, refuges for persecuted Protestants.
In the 16th century, Saumur was one of France's great Protestant strongholds. Governor Philippe Duplessis-Mornay, nicknamed the "pope of the Huguenots," founded a Protestant academy there to rival the Sorbonne. When the revocation of the Edict of Nantes (1685) banned Protestantism, entire families hid their possessions and sacred texts in the troglodyte caves — some have never been found.
The Cadre Noir of Saumur, founded in 1828, is the world's most prestigious riding school. Its riders, dressed in black, perpetuate an equestrian art inscribed on UNESCO's Intangible Cultural Heritage list. The Dolmen de Bagneux, just minutes from the center, is the largest dolmen in France (23 meters long) — proof that Saumur was keeping secrets long before recorded history.
