Domaine de Marc Seguin

The domaine de Marc Seguin is an estate in Annonay with multiple structures including residential buildings, a chapel, greenhouses, workshops, an observatory, and a caretaker's lodge arranged across the grounds. The layout reflects a working property where research, production, and daily operations took place side by side.

Marc Seguin acquired the property in 1859 and converted the ruins of a fortified house into a center for scientific inquiry and technological development. This transformation reflected his shift from military defense systems to applied research and practical innovation.

The chapel on the grounds was designed to host gatherings where people could discuss scientific ideas and share knowledge. The layout shows how learning and daily life were closely connected in this place.

The buildings and hydraulic systems are protected as heritage sites, which means public access is limited to specific dates throughout the year. Plan a visit in advance by checking when the grounds are open to visitors.

The estate includes an ingenious water system designed by Marc Seguin that channels rainwater from surrounding hills into reservoirs through a network of mechanical devices. This system demonstrates an early approach to water management using gravity and engineering that was remarkable for its time.
