The Château de Montgeoffroy is an 18th-century manor house located in the commune of Mazé, France.
In 1676, Érasme de Contades acquired the property. In 1772, the Marshal Louis Georges Érasme de Contades, governor of Alsace, decided to rebuild the château as a retirement home. He called on the Parisian architect Jean-Benoît-Vincent Barré, who worked with the local architect Simier.
The marshal being far from Anjou, the work was directed primarily by his son, le marquis de Contades, his daughter-in-law, Julie Constantin de Marans, his mistress, Hélène Hérault, and her daughter-in-law, Marie-Marguerite Magon de La Lande. It took three years.
