Château de Vallière

Château de Vallière is a castle in Gothic Revival style featuring thick walls approximately 13 meters (43 feet) in depth, housing a chapel, theater, and roughly 30 rooms with bathrooms. The structure combines defensive stonework with refined Renaissance-inspired exterior details.

The Duke of Gramont commissioned architect Alfred-Philibert Aldrophe to build this residence in 1894 within the Oise department. Construction occurred during a period of significant prosperity and architectural innovation among French nobility.

The castle houses a 17th-century tapestry bearing the Gramont and Guiche coats of arms, alongside furniture pieces originally from Beijing's Old Summer Palace. These collections reflect the owner's global connections and refined taste.

Since the castle remains private property, visits require advance arrangement with the owner. Potential visitors should contact the current proprietor to schedule an appointment.

The location lies near the site of the Battle of Mortefontaine on September 2, 1914, a significant military engagement during World War I. This conflict represented one of the closest combat encounters to Paris during that period.
