After an unusual underground getaway, the hot springs will take you to the workshops in which the secrets of a unique art craft have been preserved for 2 centuries.
The Pétrifying Fountain with its surprising 14-meter waterfall will reveal to you the ancestral know-how of the craftsman in the exploitation of calcite. At the end of the visit, the petrifies will no longer hold any secrets for you. You will then be able to appreciate the great diversity of the bas-reliefs and crystallizations created.
