Château de Franconville-aux-Bois

Château de Franconville-aux-Bois is a stone building with classical facades, decorated cornices, and pediments located in Saint-Martin-du-Tertre. The grounds include a garden with sculptures, fountains, and an orangery building.

The castle was designed and built between 1876 and 1882 by architect Hippolyte Destailleur for the Duke of Massa. It was converted into a military hospital during World War I.

The theater inside follows the style of the Bordeaux Theater and once hosted concerts during lavish parties. You can still see the room's features that made these gatherings possible.

Visits require advance arrangements and should be planned ahead of time. Information about the site's history and photography can be found at the Heritage and Photography Media Library in Charenton-le-Pont.

From 1929 to 1992, the building operated as a tuberculosis sanatorium with room for roughly 500 patients. This extended use as a medical facility left a deep mark on the interior spaces and how they were arranged.
