One of the best buried-treasure stories in Saint-Émilion begins on a winter morning in 1969. Léo de Malet Roquefort had gone out to plant a small, fallow plot in the middle of his vineyard in the Moulin du Palat section. His initial digging uncovered fragments of an ancient mosaic. He stopped and, to his credit, called the regional antiquities service rather than a bulldozer driver. Archaeologists uncovered a mosaic-paved room the same day. Excavations through 1987 revealed a substantial Gallo-Roman residence from the fourth and fifth centuries, with part of it under the road and neighboring vineyards. The mosaic ensemble is considered without parallel in the Gironde, and the site has since been reburied for its own protection.
