 Le Gros's work was completed by 1707 and sent to Cluny, where it arrived in 1709.He worked on this project in as much a French manner as he ever would and invented a spectacular sepulchral monument, at once continuing in the French baroque tradition as well as opening up new formal and iconographic avenues.The chapel was meant to receive several family members, including the cardinal himself, but first and foremost his parents, Frédéric Maurice de La Tour d'Auvergne, Duc de Bouillon and Éléonor de Bergh, Duchesse de Bouillon.
