Château de Clagny

The Château de Clagny was a French country house that stood northeast of the Palace of Versailles; it was designed by Jules Hardouin-Mansart for Madame de Montespan between 1674 and 1680. Although among the most important of the private residences designed by this great architect, it was demolished in 1769 after years of neglect. Its appearance can only be traced through the engravings made of it, and scattered references in the archives of the Bâtiments du Roi.
