The lordship of the manor changed into the hands of the Rochechouart family in 1606 when Jeanne de Beauxoncles married Rene de Rochechouart.
In 1690 Rocheux was acquired by Marc-Hyacinthe de Rosmadec, viceroy of the French West Indies and governor of the islands and mainland of America, and in around 1720 one of his descendants rebuilt the chateau. At this time the domain covered almost 1,235 acres, and included many farms : « “… He had the power of all aspects of justice over everyone in his domain, regardless of status. There is no direct evidence of his vassals paying hommage to him. However, according to state records from 1762, he had various vassals who were responsible for reporting directly to him …».
In 1791, the château was bought by the le Trosne family who rebuilt it in the style of an Italian villa.
It was at the end of the 19th Century that the Count of Villebresme transformed the Château de Rocheux and its remarkable outbuildings into what we see today.His family shield can still be seen in the main room (the wrought iron doors, the stained glass, the coat of arms).
The Chapel of Notre Dame du Sacré-Cœur, adjacent to the château, almost certainly dates from the time of the Count of Villebresme, although the archives don’t give the specific date of its construction.
