Since August, the Chantilly estate has been the subject of a preliminary investigation by the National Financial Prosecutor's Office (PNF) for "understanding and favoritism", which is interested in the conditions under which a call for tenders aimed at granting the Enghien pavilion to make it a luxury hotel was organized.

Distant heirs of the Duke of Aumale and son of Henri d'Orléans, Count of Paris who died in 2019, the brothers Eudes and Jean d'Orléans consider that the transformation of the Château d'Enghien into a luxury hotel is a "sprain" to the initial legacy of October 25, 1886, which effectively invalidates the legacy.

The Chantilly estate is indeed endowed with a very special status.

Henri d'Orléans, Duke of Aumale (1822-1897), had bequeathed in 1886 by will the immense domain, its castle, its annexes and all its collections to the Institut de France.

But he had conditioned this bequest to very strict rules, prohibiting the loan, sale or travel of the thousands of objects and paintings, to modify the hanging of the paintings or to make any change in the exterior or interior architecture. .

If ever the will of Henri d'Orléans was violated, "the present donation would be revoked and the donor and his heirs would immediately recover full ownership" of all buildings and objects, the will warned.

In a letter sent in November to the national financial prosecutor, Jean-François Bohnert, Eudes and Jean d'Orléans recalled the conditions of this legacy and expressed their "growing concern", also evoking "suspicions of the disappearance of works ".

Therefore, they asked to be considered as "direct victims" of offenses that may have been committed in the field and to intervene as such in the PNF investigation.

"If the Chantilly estate is indeed as badly managed as rumors say, a lasting solution must be found to save this jewel in the history of France", told AFP Me Olivier Baratelli, lawyer for the heirs of the Duke d'Aumale.

"If the facts are true, it is expected that the family will recover the entire estate," he said.

Contacted by AFP, the Institut de France declined to comment.
