Quai de Conti records the name of the brother of the Grand Condé. Its most prominent building is the Institut de France, the Collège Mazarin, built in 1663-70, as the Collège des Quatre Nations Réunies. Its left pavilion covers the site of the ancient Tour de Nesle, washed by the Seine, which formed the boundary point of Philippe-Auguste's wall and rampart. Mazarin's will endowed the college for the benefit of sixty impecunious gentlemen's sons of Alsace, France, Pignerol, Roussillon. The Revolutionists styled it "Collège de l'Unité," then in 1793 suppressed it, and used the building for meetings of the Salut Public, later as an École Normale, then as a Palais des Arts; finally, after undergoing restoration, it became in 1805 the Institut de France, as we know it. The ancient chapel has been taken for the great meeting-hall, the hall of the grandes "Séances." For long Mazarin's tomb, now in the Louvre, was there. His body is said to be there still, deep down beneath the chapel pavement. The Bibliothèque Mazarine is in the part of the building covering the spot where the petit hôtel de Nesle stood of old. The greater part of the statesman's valuable collection of books was brought here from his palace, now incorporated in the Bibliothèque Nationale, Rue de Richelieu, according to his will. It contains many precious ancient volumes and manuscripts. The house No. 15 was built by Louis XIV on the foundations of the ancient Tour de Nesle. No. 13, where we see the shop of the booksellers Pigoreau, was built by Mansard, in 1659, one of its walls resting upon a bit of the ancient wall of Philippe-Auguste. Here, on the third story, we may see the room, an attic then, as now, where young Buonaparte, a student at the École Militaire, used to spend his holidays, welcomed there by old friends of his family. The short Rue Guénégaud, memorizing the mansion once there, bordering at one part the walls of the Mint, shows us along the rest of its course, at No. 1, remains of a once famous marionnettes theatre; at No. 19 an old gabled house; in the court, No. 29, a tower of Philippe-Auguste's wall; an ancient inscription at No. 35; a fine old door at No. 16, etc. The narrow old-world Rue de Nevers shows us none but ancient houses. This thirteenth-century street was formerly closed at both ends and known therefore as Rue des Deux-Portes. Beneath No. 13 of the little Rue de Nesle runs an ancient subterranean passage blocked in recent years. The old house at No. 5 of the quay was for long looked upon as the dwelling of Buonaparte after he left Brienne. At the recently razed No. 3 lived Marie-Antoinette's jeweller, his shop surmounted by the sign "Le petit Dunkerque," referring to articles of curiosity in the jewellery line, much in vogue in the year 1780. A little café at No. 1, also razed, was till lately the humble successor of the first Paris "Café des Anglais," set up there in 1769, a gathering-place for British men of letters.
