Royal Chapel of Saint Louis, Dreux: Overall view, facade of the Royal Chapel

The House of Orl\u00E9ans was founded by Philippe de France, duc d'Orl\u00E9ans, the younger brother of Louis XIV of France. The house rose to prominence during the French Revolution and once again during the reign of Louis-Philippe of France. The burials were once in the chapel of the Coll\u00E9giale Saint-\u00C9tienne de Dreux, but this was destroyed during the Revolution and the bodies thrown into a mass grave. In 1816, the Duchess of Orl\u00E9ans had a new Neoclassic chapel built on the site of the mass grave of the Chanoines cemetery. In 1830, Louis-Philippe I, King of the French, her son, embellished and enlarged the chapel (in a Neo-Gothic style) which was renamed Chapelle royale de Dreux, now the necropolis of the Orl\u00E9ans royal family. Sculptors include Millet, Barre, Lenoir, Pradier and Merci\u00E9r.
