The Manse Pavilion houses the machine princes and hydraulic machines of the Duke of Aumale. 

Le Moulin des Prince s: Built in 1678, the Manse machine (hydraulic engineer named Jacques de Manse) supply water to large water gardens, (fountains, waterfalls) of the princes. This exceptional machine was restored by the Pavillon Jacques de Manse, which now manages the site association. 

The machines of the Duke of Aumale : Much more recent, were intended to supply drinking water to the city of Chantilly. An ultra-modern laundry in the late 19th century completes the tour.

A leap in time, a visit to a little-known industrial heritage accessible and playful fun with the experiments conducted to understand the operation of any mill.
