Origin and history

The château de Franconville, located in Saint-Martin-du-Tertre in the Val-d Inspired by François Mansart's Château de Maisons-Laffitte, it is an improved version, surrounded by a park of 90 hectares decorated with factories and statues in patinated cast iron. The estate, which has been listed as a historical monument since 1987, preserves remarkable elements such as a neoclassical theatre, an orangery, and a rotunda inspired by Versailles.

The site has a medieval history, linked to the seigneury of Franconville-aux-Bois, mentioned as early as 832 in a charter of Saint-Denis Abbey. In the 15th century, the seigneury passed into the hands of the d-O family, then to the Brancas in the 18th century. The present castle replaces an earlier building, rebuilt or modified by Paul-Louis de Thélusson in 1782, before being acquired by Louis-Aspais Amiot, then by the Leroux family, who added a troubadour tower in 1840.

In the 19th century, the Duke of Massa, heir to a colossal fortune, transformed the estate into a place of fabulous receptions, welcoming artists like César Franck and André Messenger. After his death in 1913, the castle became a sanatorium in 1929, a function he retained until 1992. The estate, partially restored in 2007, is now open for rent for private events, with an exceptional room opening project planned for 2024.

The park, attributed without proof to Louis-Sulpice Varé, houses notable architectural elements such as a monumental fountain, marble sphinges, and cast-iron replicas of classical statues. The theatre, inspired by Bordeaux, could accommodate up to 528 seats. Despite the deteriorations and thefts in the 20th century, the castle and its estate remain an exceptional testimony to the eclectic architecture and aristocratic lifestyles of the late 19th century.

The castle also served as a setting for films like Lucie Aubrac and series like The Walking Dead: Daryl Dixon. Its recent history is marked by aborted projects of transformation into a luxury hotel (2014-2019) and preservation efforts led by local associations. Today, it embodies both a major architectural heritage and a restoration challenge for future generations.
