At the entrance to this church is a small museum housing the statues of saints that are borne through the streets in the Ash Wednesday procession, of which the most remarkable is a St Louis dressed up as Louis XIII! The church's exuberant gilded wood decor (1700-1737), the work of Manuel and Francisco Xavier de Brito, constitutes one of Brazil's most accomplished examples of Baroque art. The Apotheosis of St Francis, on the ceiling of the nave, is the work of Caetano da Costa Coelho and is Brazil's first example of perspective in art.
