Standing next to the forest, this long building was constructed in 1769 by the architect Jean François Leroy to house the numerous guests of the Prince de Condé. In the 18th century, Chantilly was in fact the venue for numerous garden fêtes and hunting parties that were attended by royalty and ambassadors, and the Château was not big enough to put up all of the guests. It is now called the Château d'Enghien, in honour of the last descendent of the Bourbon Condé family, who was born in Chantilly in 1772 and lived here in his infancy with his nursemaids. Today, the Château d'Enghien houses the apartments of the members of the Institut de France who look after Chantilly's interests, including the historian and former minister Alain Decaux, of the Académie Française, the architect Christian Langlois, of the Académie des Beaux-arts, or the "bosses' boss" Yvon Gattaz, member of the Académie des Science morales et politiques.
