The Château de Villers-Cotterêts (pronounced [ʃɑto d(ə) vilɛʁ kɔt(ə)ʁɛ]) is a historic French château located in the town of Villers-Cotterêts in the Aisne department, Hauts-de-France, about 80 kilometres (50 miles) north-east of Paris.

In 1539, Francis I of France signed the Ordinance of Villers-Cotterêts which made the use of the French language mandatory in the acts of administration and justice.

In 1661, Louis XIV granted the castle to his brother Philippe I, Duke of Orléans.

In 1787 Louis Philippe II, Duke of Orléans was exiled to the château over opposition to the May Edicts in 1787.

[2] In 2023, following a colossal restoration campaign, president Emmanuel Macron turned the castle into the Cité Internationale de la Langue Française, dedicated to the French language.
