Voltaire spent the last twenty years of his life in this château in Ferney, which he had built himself. It was here that he received the Calas family, wrote his Treatise on Tolerance, and became one of the leading exponents of the Enlightenment during the 18th century.
Untouched since it was purchased by the French State in 1999, the château needed restoration throughout in order to better accommodate the public. The project brought out all the site’s major heritage values since its construction, revisited the forgotten polychromy on its facades, and fitted out a space in the base of the building that can be used for exhibitions.
