Château de Cirey

The Château de Cirey is a château in Cirey-sur-Blaise, Haute-Marne, France (not to be confused with Bellevaux Abbey in Haute-Saône, sometimes also referred to as the chateau of Cirey-lès-Bellevaux). The château was the home of Émilie du Châtelet and her lover Voltaire from 1734 to 1749.

Today the château is owned by the count of Salignac-Fénelon. Various parts of the building and its interiors have been protected as a monument historique since 21 September 1981.
