Château de Saint-Mars-la-Jaille

Château de Saint-Mars-la-Jaille is an 18th-century castle designed by Pierre Charles Gaignard with outbuildings that were restored in the early 1900s. The property has been registered as a historical monument since 1994 and sits in the Loire-Atlantique department.

A fortified structure stood on the site from 1334 but was destroyed by order of King Henry IV in 1598 and again under Cardinal Richelieu in 1618. Only the dovecote remained standing until the current castle was built in 1764.

The interior features Rococo wall panels that originally came from a townhouse in Nantes. These decorative elements were installed during restoration work in the early 20th century and define the character of the rooms today.

The site is located in Vallons-de-l'Erdre in the Loire-Atlantique department of western France. When visiting, allow time to explore the outbuildings and grounds to appreciate the full scope of the property.

The construction of the castle in 1764 relied on forced labor from surrounding villages, which sparked strong protests. These complaints were documented in records from the period and reveal the tensions surrounding the building project.
