Château de l'Arrouaise

The Château de l'Arrouaise is a brick manor house with slate roofing in Oisy, northern France, built with forty windows and two ornamental towers. The property contains extensive cellar vaults, an English-style garden, and vegetable plots on its grounds next to two active farms.

The estate came into the hands of Henri d'Orleans, Duke of Aumale and fourth son of King Louis-Philippe I, when he inherited the vast Guise domain in 1830. It was constructed in the 1850s as a modern manor to represent new farming methods of the era.

The château shows how wealthy landowners lived alongside farming operations, built by Baron Seillière as a modern country house for managing his agricultural estates. The rooms and gardens reveal the way prosperous families organized and used their land during the 1800s.

The grounds are surrounded by two working farms, giving the place an agricultural character that visitors can experience while walking around the property. The English garden and extensive cellar system are significant features that can be explored during a visit.

The site was built in 1857 on land cleared from the ancient Arrouaise forest region. This woodland had existed since prehistoric times and covered the area for centuries before being removed to make way for the estate.
