Château de Neuilly

The château de Neuilly is a former château in Neuilly-sur-Seine, France. Its estate covered a vast 170-hectare park called "parc de Neuilly" which comprised all of Neuilly that is today to be found between avenue du Roule and the town of Levallois-Perret.

It was built in 1751. Acquired by the House of Orléans in 1819, the château was looted and burned during the French Revolution of 1848. In 1852 it was confiscated by Napoleon III along with other properties of the Orléans family, and the estate was subsequently subdivided from 1854 onwards.

Today, only one wing of the château survives. This section, designed in the 19th century by the architect Pierre-François-Léonard Fontaine, was later incorporated in 1908 into a convent complex built by Maurice Humbert for the Congregation of the Sisters of Saint Thomas of Villeneuve, located at 52, boulevard d’Argenson.
