At Moyencourt (Somme), a large cultual Gallo-Roman enclosure was discovered. The numerous remains found there came from three wells, the use of which seems to have been quite different. The two wells outside the enclosure, to the north of the site, at the entrance to a road, seem to be devoted to household or artisan purposes. The third well on the contrary is in the very middle of the enclosure, revealing a special status. The analysis of the wood vestiges thus helps to shed a special light on the way this sanctuary functioned. Traduction : Margaret & Jean-louis CADOUX.
