The main "gem" of the estate is certainly its castle. Built in the 16th century, the Château de Chantilly is connected to four powerful French dynasties: Montmorency, Condé, d'Orgemont and d'Aumale. The castle's art gallery, the Musée Condé, has the rarest library and the second most valuable collection of art paintings after the Louvre. Here are the creations of Raphael, Botticelli, Delacroix, Poussin.
