Can be visited as part of the tour of the Cremant cellar in Monmousseau.
The extraction of tuffeau (limestone) used to build castles, churches and abbeys as well as houses left thousands of kilometers of underground passages on the plain and on the slopes.
People quickly knew how to take advantage of these excavations, the tenderness of the noble limestone, to exhibit houses and cave cellars. If the troglodytic housing environment made it possible to protect oneself and defend oneself against the attackers, it offered other numerous advantages.
Isothermal, safe and reassuring, it cost almost nothing and at the same time grew with the family.
