The Salon de Guise contains family portraits, including the Duke of Aumale aged nine, the year after he inherited Chantilly, and those of his two sons, Louis of Guise, and Francois. The room was renamed in 1872 after the death of the Duke of Aumale's second son, Francois, Duke of Guise.
The Duchess of Aumale's Bedroom.
The ceiling in the Duchess's Bedroom was painted by N. Diaz de la Pena.
The Duchess of Aumale's Boudoir is a round room that was originally hung with green fabric. After the death of the Duchess in 1869, on the instructions of the Duke the walls and furniture were covered in purple fabric woven with silver, the colour of mourning.
The Petite Singerie divided the Duke's and Duchess's rooms. It was decorated in the 1730's by Christophe Huet, a famous animal painter in France. It is a small room that depicts monkeys imitating the daily activities of the aristocracy in a world that looks very like Chantilly.
The Duke of Aumale's Bathroom.
The Salon de Conde. On the walls are hung 42 framed medallions with likenesses of members of the house of Bourbon-Conde so that the Duke of Aumale originally called this room "the Condes Family Salon". It was renamed the "Conde Salon" in memory of Louis of Orleans, Prince of Conde, eldest son of the Duke of Aumale.
The Duke of Aumale's Bedroom is furnished with a military bed. The paintings are of members of his family including his mother by Baron Francois Gerard. The room is unchanged since 1897.
The Marble Salon was the Duke's private dining room and it was decorated by Eugene Lami in the Neo-Renaissance style.
