Origin and history

The ancient tanks of Trémonday are Gallo-Roman remains located in the municipality of Batz-sur-Mer, in the Loire-Atlantique department. These structures, intended for the collection and storage of water, reflect the advanced hydraulic techniques of this period. Their presence attests to the importance of water resources for local populations, probably linked to agricultural or domestic activities.

The site was recognized for its heritage value as early as 1918, when it was listed as historic monuments. This official protection underscores its archaeological and historical interest, although the precise details of its construction or daily use are not explicitly documented in the available sources. Today, these tanks remain a tangible testimony of the Gallo-Roman occupation in the region of the country of Gerande.

The location of the tanks at 7353 Rue de Tremondais is specified by GPS coordinates, and the site is managed by an association. Although their accessibility to the public is not clearly mentioned, their classification makes them a key element of local heritage. Their state of conservation and their integration into the current landscape of Batz-sur-Mer make it a subject of study for historians and archaeologists interested in the ancient period in the Pays de la Loire.
