On September 19 and 20, 2026, heritage sites will be open to all. Many tourist and heritage sites, some normally closed to the public, will reveal their history in the Ardennes Valley. This 43rd edition will celebrate the heritage of photography, on the occasion of the bicentenary of its invention, alongside the national theme "Heritage in Peril: Reviving, Resisting, Reimagining."
