The walls of the side vaults of the two sanctuaries, the crypt and upper church, are covered with a first level of marble slabs. The upper walls of these side vaults are occupied by painted ex-votos hung in several rows above; the most recent are on the walls of the terraces of the basilica. Most of these ex-votos date only from the second half of the 19th century; earlier ones disappeared during the Revolution. Most depict shipwrecks and storms, but there are also very different scenes: fire, car and railway accidents, bedridden patients, and political and social events. The events of May 68 were the inspiration for one drawing; an Olympique de Marseille flag recalls that the players of the club mounted a pilgrimage to the basilica after a victory.
