Château de Carnelle is really the Château de Franconville-aux-Bois (also known as the château de Saint-Martin-du-Tertre and Castle of Franconville) and is off of the Rue Corentin Celton, in the commune of Saint-Martin-du-Tetre, the department of Val-d’Oise, the Ile-de-France region of France.
The castle of Franconville has been nicknamed the Chateau de Carnelle due to its proximity to the Carnelle forest. The construction began in 1876 and was not completed until 1890. The Chateau de Franconville was built at the request of the Duke of Massa by Gabriel-Hippolyte Destailler. It is stylized in Renaissance Revival and is a copy of the Chateau de Maisons-Laffitte in Yvelines. There are 12 bedrooms on the first floor, 6 on the second and rooms for maids and servants in the attic. The large estate offered a park, lake, orangery, theater, and gardens.
Over the years the chateau was used for a great many of things including a home for feasts and fantastical parties by the Duke of Massa, later a military hospital during World War I and then it was sold and transformed into a sanatorium in 1924. It was a sanatorium until 1992.
The castle was listed as a historical site in 1951 and named a historic monument in 1987.
Today the windows of castle and the theater are sealed with brick and painted to look real. Alarm systems have been installed on the doors. It now belongs to the Hospital Carnelle which has some staff housing and a long care facility for the elderly a short distance away from the castle.
