Mentioned since the Middle Ages, the land of Sandricourt belonged to the Hédouville family, the organizers of the famous 'Pas d’Armes de Sandricourt.' In 1493, in a sensitive political context, the land of Sandricourt hosted over 4,000 people for a multi-day tournament. This event was particularly exceptional as it brought together the most influential knights and lords of the Kingdom of France.
As centuries passed, this land was passed from the Saint-Simon family to the de Banne family, eventually becoming a barony that saw the disappearance of the old medieval fortress in the 19th century. All that remains today is the chapel.
For most of the 19th century, the Sandricourt Estate belonged to the Beauvoirs family, who made it a preferred destination for hunting. As the destination gained recognition, the park was developed. Between 1880 and 1900, Henri and Achille Duchêne, two famous French landscape architects, designed the Marquise Alley. This double alley, lined with lime trees, stretches for over 4 kilometers. It was classified as a historical monument by order of July 18, 1991.
In 1908, the property was purchased by the American Robert Walton Goelet, of Vendée origin. A landowner, banker, and married to the daughter of a French wine merchant, he developed the Sandricourt Estate for several decades. Thus, on the eve of World War II, the Sandricourt Estate covered 5,000 hectares.
