Rue Jacob, lengthened in the nineteenth century by the Rue Colombier, ancient Chemin-aux-Clercs, owes its name to a chapel built by Margaret de Valois, la Reine Margot--dedicated to the Hebrew patriarch in fulfilment of a vow when the Queen was kept in durance in Auvergne. The street has always been the habitation of notable men of letters, artists, etc. Sterne lived at No. 46. No. 47, Hôpital de la Charité, another of Marie de’ Medici’s foundations, was built for the Frères de St-Jean-de-Dieu. The firm of chemists at No. 48--Rouelle--dates from 1750, formerly on the opposite side of the street. At No. 19 we see in the courtyard vestiges of the old abbey infirmary. The abbey gardens stretched across the site of several houses here. No. 26, hôtel Lefèvre d’Ormesson (1710). At No. 22 there is an eighteenth-century structure in the court called “temple de l’Amitié.” At No. 20 dwelt the great eighteenth-century actress, Adrienne Lecouvreur. In Rue Furstemburg we find vestiges of the abbey stables and coach-house. Rue de l’Abbaye, opened in the last year of the eighteenth century, stretches across a line once in the heart of the famous abbey grounds. The first church on the site of the fine old edifice we see there now, was built under the direction of Germain, bishop of Paris, in the time of Childebert, about the middle of the sixth century, dedicated to St-Vincent and known as St-Vincent et Ste-Croix, on account of its crucifix form. Bishop Germain added a monastery. In the ninth century came the devastating Normans. The church and convent were destroyed to be rebuilt on so grand and extensive a scale two centuries later, strongly fortified, surrounded by a moat, watch-towers, etc.--a masterpiece of thirteenth-century architecture. In the eighteenth century the abbey prison was taken over by the State, the Garde Française lodged there. In September, 1792 Mme Roland, Charlotte Corday and many another notable prisoner of those terrible days were shut up within its walls. The fine library and beautiful refectory were burnt and there, that fatal September, saw some three hundred victims of Revolutionary fury put to death, the greater number slain on the spot where Rue Buonaparte touches the _place_ in front of the church. The prison stood till 1857. The church is full within as without of intensely interesting architectural and historic features: its tower is the most ancient church tower of the city. In the little garden square we see the ruins of the lady-chapel built by Pierre de Montereau, architect of the Ste-Chapelle. The Gothic roof, the round-arched nave, the splendid chapel of the Sacré-Cœur, once the church choir, with its pillars coloured deep red, the wonderful capitals of the chancel, the old glass in the chapel Ste-Geneviève, the tombs and the statues, and Flandrin’s glorious frescoes, all appeal to the lover of the beautiful and the historic.
