The Billecart family has always supported its local community, especially through difficult times such as wars or epidemics. In the late 1930s, before becoming the mythical vineyard that is the Clos Saint-Hilaire today, this parcel included a small orchard, a large walnut tree and an English garden. When the Second World War broke out in 1939, Charles Roland-Billecart immediately had a foreboding sense of impending hardships, predicting the long periods of deprivation that the country would have to endure. He turned it into a vast vegetable garden and the land adjoining the cellars became a beautiful orchard. The harvested crops made it possible to feed the family, the House staff and certain inhabitants of the village during these 4 hard years. It is not until 1964 that Jean Roland-Billecart planted the very first Pinot Noir vines of the Clos Saint-Hilaire on this parcel.
