The Château de la Solitude is a ruined castle located in a wooded park within the territory of the commune of Le Plessis-Robinson1. It is actually a neo-Gothic style castle with a ground area of 480 square meters featuring a central inner courtyard (originally covered with a ribbed glass brick vault), built in 1903 by a wealthy Parisian chocolatier, François-Philibert Marquis.
It then served as a rest home where René Viviani stayed, and as a residence for a Carmelite congregation. It was later bought by the State, which turned it into a technical education college for young single mothers, closed in 1973. In 2016, the film "Elles... Les Filles du Plessis" tells the story of these young single mothers and their living conditions.

In 1977 and 1987, fires devastated it2. The writer Raymond Radiguet used it as the backdrop for his novel Le Bal du comte d'Orgel (published in 1924, posthumously). The park surrounding these ruins is state-owned but managed by the General Council of Hauts-de-Seine. It mainly consists of oaks and chestnut trees and is home to some wild animal species.
