Heritage Days 2025 at Château de Mesnil-Voysin (91), the program for this year's event

The Essonne town of Bouray-sur-Juine boasts a splendid 17th-century château. The Château de Mesnil-Voysin, built by the famous mason Michel Villedo, welcomes us on September 20 and 21, 2025. To celebrate the Journées du Patrimoine (Heritage Days), the monument is organizing various tours and events, so that the curious can discover the history and special features of this site.

This centuries-old castle is currently being restored. However, time has not been enough to erase its superb appearance. The monument is adorned with over 300 windows, dormer windows of various shapes, and a massive dovecote, topped by a pepperpot housing 3,500 boulins (indoor nesting boxes). An orangery, workshops and dry moat can also be admired by visitors.
