Origin and history

The caves of the Houillottes, located in Courjeonnet, constitute an underground monument whose origins and period of creation are not specified in the available sources. Their exact nature and historical use are thus not well known, with no precise date or contextualization. In the Greater East, caves and underground cavities have often played a role in local life, whether as shelters, storage sites or sites linked to artisanal or mining activities.

In Courjeonnet, as in other rural communes, these spaces could be integrated into the daily practices of the inhabitants, although their exact function for the Houillottes is not attested.
