Pause first outside St-Sulpice. The 1844 fountain by Visconti displays the sculpted likenesses of four bishops of the Louis XIV era: Fenelon, Massillon, Bossuet, and Flechier. Work on the church, at one time Paris's largest, began in 1646. Though laborers built the body by 1745, work on the bell towers continued until 1780, when one was finished and the other left incomplete. One of the priceless treasures inside is Servandoni's rococo Chapelle de la Madone (Chapel of the Madonna), with a Pigalle statue of the Virgin. The church has one of the world's largest organs, comprising 6,700 pipes; it has been played by musicians like Charles-Mari Widor and Marcel Dupré.

The real reason to come here is to see the Delacroix frescoes in the Chapelle des Anges (Chapel of the Angels), the first on your right as you enter. Look for his muscular Jacob wrestling (or dancing?) with an effete angel. On the ceiling, St. Michael is having some troubles with the Devil, and yet another mural depicts Heliodorus being driven from the temple. Painted in Delacroix's final years, the frescoes were a high point in his baffling career. If these impress you, pay the painter tribute by visiting the Musée Delacroix.
