The Hôtel-Dieu on the north side of the Parvis is the modern hospital raised on the site of the ancient Paris House of God, the hospital for the Paris poor built in the thirteenth century, always in close connection with the Cathedral and having its _annexe_ across the little bridge St-Charles, a sort of covered gallery. Those blackened walls stood till 1909. Rue du Cloître Notre-Dame belonged in past ages to the Cathedral Chapter, a cloistered thoroughfare. Its fifty-one houses have almost entirely disappeared. Three still stand: Nos. 18, 16, 14. Pierre Lescot, the notable sixteenth-century architect, to whom a canonry was given, died there in 1578. Rue Chanoinesse is still inhabited by the Cathedral canons. Its houses are all ancient. At No. 10 lived Fulbert, the uncle of the beautiful Héloïse, who braved his anger for the sake of Abelard, who lived and taught hard by. Racine is said to have lived at No. 16. The old Tour de Dagobert, which did not, however, date back quite to that monarch’s time, stood at No. 18 till 1908. Its wonderful staircase, formed of a single oak-tree, is at the Musée Cluny. Lacordaire is said to have lodged at No. 17. A curious old courtyard at No. 20. At No. 24, vestiges of the old chapel St-Aignan (twelfth century). At 26, a passage with old pillars and paved with old tombstones. Leading out of it runs the little Rue des Chantres where the choristers lived and worked to perfect their voices and their knowledge of music. Rue Massillon is entirely made of old houses with most interesting features--a marvellous carved oak staircase at No. 6, fine doors, curious courtyards. Another beautiful staircase at No. 4. In Rue des Ursins, connected with Rue Chanoinesse, we find many ancient houses. At No. 19 we see vestiges of the old chapel where Mass was said secretly during the Revolution by priests who went there disguised as workmen. Rue de la Colombe, where we find an inscription referring to the discovery there of Roman remains, dates from the early years of the thirteenth century. CHAPTER X L’ÎLE ST-LOUIS Crossing the bridge painted of yore bright red and known therefore as le Pont-Rouge, we find ourselves upon the Île St-Louis, in olden days two distinct islands: l’Île Notre-Dame and l’Île-aux-Vaches, both uninhabited until the early years of the seventeenth century. Tradition says the law-duels known as _jugements de Dieu_ took place there. The Chapter of Notre-Dame had certain rights over the island. In the seventeenth century, consent was given for the Île St-Louis to be built upon, and the official constructor of Ponts and Chaussées obtained the concession of the two islets under the stipulation that he should fill up the brook which separated them, and make a bridge across the arm of the Seine to the city quay. The brook became Rue Poulletier, where we see interesting vestiges of that day and two ancient _hôtels_, Nos. 3 and 20--the latter now a school.
