A masterpiece of classical architecture, the Château de Vaux-le-Vicomte, located outside Paris, was the forerunner of Versailles. Contained within its walls are three and a half centuries of history. That legacy is now the responsibility of the three brothers who inherited it on the death of their father: Ascanio, Alexandre and Jean-Charles. The château is regularly the scene of construction sites but some restoration must be done by hand, for instance to restore the central wrought iron gates to their former glory. FRANCE 24 takes you behind the scenes.
