There are records of the seigneurie de Boursault from the 14th century, when Robert de Flandre, seigneur de Brugny, ceded the land to Geoffroy de Naast.
The present Château de Boursault was built by Madame Clicquot Ponsardin (1777-1866), founder of the Veuve Clicquot Champagne house, in honor of the marriage of her granddaughter Marie Clémentine de Chevigné to Louis de Mortemard-Rochechouard in 1839.
