The main altar was built of Golfolina stone with columns of Spanish marble. Behind the altar is a statue of the Madonna holding a bouquet, the Vierge au Bouquet. Joseph-Elie Escaramagne obtained this statue for the original chapel in 1804. At first the Madonna held a sceptre, but due to the sceptre's poor condition, it was replaced by flowers. Two staircases flanking the main altar lead to the sacristy buildings and the choir above, but they are off-limits to the public.
