Chantilly is named after Cantilius, a Roman who owned a villa there. During the middle ages, a castle was built in Chantilly. It belonged to the lords of Senlis and played an important role during the hundred years war.
The castle was transformed during the 17th century, by its owner the Grand Condé. The gardens were done during this period by Le Notre, the orangerie by Mansard. The castle was later damaged during the French revolution. It now belongs to the Institut de France.
Chantilly also has a long established race horse breeding and training tradition.
