This was originally placed above the altar, but between 1264 and 1267, it was placed atop a high tribune in the apse of the church, where everyone could see it. In 1306, a new sacred relic was added: a portion of the skull of Louis himself, since he had been declared a saint. During the French Revolution, the Chasse and the vessels holding the relics were taken apart and melted down for their jewels and precious metals. The fragment of the cross was transferred first in 1793 to a collection of antiquities, then given to the Bishop of Paris. A new reliquary of gold and crystal was made for the crown of thorns. Since the Concordat of 1801, it was displayed in the treasury of the cathedral of Notre Dame de Paris, but it was saved from the Notre-Dame de Paris fire on 15 April 2019 and has since been kept in the Louvre Museum. Other Saintes-Chapelles Prior to the dissolution of the Sainte-Chapelle in 1803, following the French Revolution, the term "Sainte-Chapelle royale" also referred not only to the building but to the chapelle itself, the choir of Sainte-Chapelle. However, the term was also applied to a number of other buildings. Louis IX's chapel inspired several "copies", in the sense of royal or ducal chapels of broadly similar architectural form, built to house relics, particularly fragments of Louis' Passion Relics given by the King. Such chapels were normally attached to a ducal palace (e.g. Bourges, Riom), or else to an Abbey with particular links to the royal family (e.g. St-Germer-de-Fly). As with the original, such "Holy Chapels" were nearly always additional to the regular palatine or abbatial chapel, with their own dedicated clergy—usually established as a college of canons. For the patrons, such chapels served not only as public expressions of personal piety but also as valuable diplomatic tools, encouraging important visitors to come and venerate their relics and showing their connection to the French crown. Notable Saintes-Chapelles in France include: Bourbon-l'Archambault: Founded c.1310 by Louis IX's grandson, Duke Louis I de Bourbon to house a fragment of the True Cross Chambéry: Founded c. 1400 Châteaudun: Founded 1451 Bourges: Founded 1392 by Duke Jean de Berry decorated with sculptures and stained glass by André Beauneveu. Now destroyed. Riom: Founded 1382 by Jean de Berry Saint-Germer-de-Fly Abbey: A very similar structure, also called the Sainte-Chapelle, was erected twelve years after
