Domaine de Sillery

Domaine de Sillery is a stately estate in Épinay-sur-Orge with a mansion, ponds, underground caves, and wooded areas set within a designed landscape. The grounds span approximately 30 hectares and portions are used today for educational facilities.

The estate was founded in the 19th century and took its present form when landscape architect Louis-Sulpice Varé designed the park in 1837 with an elaborate water system. The property was later preserved as a cultural site and adapted for contemporary uses.

The Franco-British Foundation runs cultural events and exhibitions on the grounds that make the heritage accessible to visitors. The estate today serves as a place for educational programs and activities that bring people together.

The grounds today house educational facilities and are best explored on foot, with various areas like the ponds and woods accessible to visitors. It is advisable to wear sturdy shoes as the ground conditions vary depending on the season.

The grounds served briefly as an operational hub for the mobile emergency response teams of Essonne during the 2020 pandemic. This shows how the historic site adapted to meet contemporary needs when called upon.
