Sainte-Chapelle de Vincennes

The Sainte-Chapelle de Vincennes is a Gothic royal chapel within the fortifications of the Château de Vincennes on the east edge of Paris, France. It was inspired by the Sainte-Chapelle, the royal chapel within the Palais de la Cité in Paris. It was begun in 1379 by Charles V of France to house relics of the Passion of Christ. It is no longer used as a church, and is now a French historical monument operated by the Centre des monuments nationaux.
