The Cope of St Louis d'Anjou is a medieval garment now in the Basilica of Saint Marie Magdalena in the town of Saint-Maximin-la-Sainte-Baume, in the Provence-Alpes-Côte d'Azur region of southeastern France. The cope is closely linked to the history of the basilica, the construction of which started in the late thirteenth century, but it was never finished.
