In 1840, a project was undertaken for the design of the chariot intended to carry the ashes of Napoleon I, who had died in captivity on the island of Saint Helena on 5 May 1821. This highly symbolic event, known as the Retour des Cendres, was orchestrated under the direction of Adolphe Thiers and King Louis-Philippe, reflecting a broader effort to reconcile the legacy of the Empire with the July Monarchy. The translation of Napoleon’s mortal remains to their final resting place at Les Invalides was not only a moment of national pageantry but also a carefully planned architectural and ceremonial undertaking. Henri Labrouste, noted for his innovative approach to public architecture, was entrusted with overseeing the ceremonial aspects of the transfer, working in collaboration with Louis Visconti, who would later design the emperor’s tomb. His watercolour depicts a chariot designed in a neoclassical style, featuring purple drapery, allegorical statuary, laurel wreaths, and other classical elements. At its centre stands a sculptural catafalque, surrounded by symbolic figures, military standards, and French flags. A team of horses and uniformed attendants emphasises its ceremonial function.
