The Sainte Chapelle, is a Palatine chapel built on the Ile de la Cité at the request of the king Saint-Louis to host the Crown of thorns, a piece of the Real Cross, as well as other diverse relics of the Passion which he had acquired from 1239. Although the construction was fast, no structural defects were found, and the decoration was not neglected. The decoration of Sainte Chapelle calls on different artistic techniques, especialy sculpture, painting and the art of stained-glass window making : the immense original stained-glass windows now makes the fame of the Sainte-chapelle, because it was deprived from her relics in the French Revolution, and by that, lost its main reason for being.
