The church St-Sulpice, with its very characteristic façade, the work of Servandoni, was begun in the middle of the seventeenth century on the site of a thirteenth-century church dedicated to St. Pierre, but was not finished till nearly a century later. Servandoni’s towers were disapproved of; one was demolished and rebuilt by Chalgrin. The other remains as Servandoni designed it. Entering the church we see its walls covered with frescoes and paintings; they are all by celebrated artists. Those in the lady-chapel by Van Loo, the rest by Delacroix and other masters of modern times. The high altar is unusually large. The shells for holy water were a gift from the Republic of Venice to François I. The pulpit with its carved figures was given by Richelieu. In the Chapelle-des-Étudiants is an organ that belonged to Marie-Antoinette for the use of her young son, and has been played by Glück and Mozart. A sacrilegious fête was held in the church in Revolution days and a great banquet given in honour of Napoléon. The grand organ is very fine, its woodwork designed by Chalgrin. The services are noted for the beauty of their music. The _place_ dates from 1800, built on the site of the ancient seminary “des Sulpiciens,” razed by Napoléon. The present Séminaire, no longer a seminary--forfeited to the State in 1906--was built in 1820-25. The immense fountain was put up there nearly half a century later, an old smaller one taken away. Almost parallel with Rue Bonaparte the old Rue de Seine stretches from the banks of the river to Rue St-Sulpice. It dates in its most ancient part from 1250 as the Pré-aux-Clercs road. No. 1 is a dependency of the Institute. No. 6 is on the site of a _palais_ built by la Reine Margot on leaving l’hôtel de Sens, some traces of which are seen among the buildings on the spot, and part of the Queen’s gardens. No. 10 was formerly the Art School of Rosa Bonheur. At No. 12 are vestiges of l’hôtel de la Roche-Guyon and Turenne (1620). Nos. 41, 42, 57, 56, 101 show interesting seventeenth-century features. Rue Mazarine is another parallel street--a street of ancient houses. No. 12 is notable as the site of the Jeu de Paume, a tennis-court, where in 1643 Molière set up his Illustre théâtre. No. 30, hôtel des Pompes, where died in 1723 the founder of the Paris Fire Brigade; a remarkable man he ... an actor in Molière’s troup, the father of thirty-two children! On the site of No. 42 stood once another tennis-court, which became the théâtre Guénégaud, where the first attempts at Opera were made. Rue de Nesle, till the middle of last century Rue d’Anjou-Dauphine, stretches across the site of part of the famous hôtel de Nesle; a subterranean passage formerly ran beneath it. The interesting house No. 8 is one of the many said to be a palace of la Reine Blanche, the mother of St. Louis. There were, however, as a matter of fact, many “Reines Blanches” in France in olden times, for royal French widows wore white, not black for mourning.
