We are now in the vicinity of the largest and most important of the Paris cemeteries--Père Lachaise. But it lies in the 20th arrondissement. The streets of this 10th arrondissement leading east approach its boundary walls--its gates. Rue de la Roquette comes to it from the vicinity of the Bastille. La Roquette was a country house built in the sixteenth century, a favourite resort of the princes of the Valois line. Then, towards the end of the seventeenth century, the house was given over to the nuns Hospitalières of Place-Royale. The convent, suppressed at the Revolution, became State property and in 1837 was used as the prison for criminals condemned to death. The guillotine was set up on the five stones we see at the entrance to Rue Croix-Faubin. The prisoners called the spot l’Abbaye des Cinq Pierres. It was there that Monseigneur Darboy and abbé Deguerry were put to death in 1871. On the day following fifty-two prisoners, chiefly monks and Paris Guards, were led from that prison to the heights of Belleville and shot in Rue Haxo. Read _à ce propos_ Coppée’s striking drama _Le Pater_. La Roquette is now a prison for youthful offenders, a sort of House of Correction. Lower down the street we find here and there an ancient house or an old sign. The fountain at No. 70 is modern (1846). The curious old Cour du Cantal at No. 22 is inhabited mostly by Auvergnats. Rue de Charonne, another street stretching through the whole length of the arrondissement, in olden days the Charonne road, starts from the Rue du Faubourg St-Antoine, where at No. 1 we see a fountain dating from 1710. Along its whole length we find vestiges of bygone times. It is a district of ironmongers and workers in iron and workman’s tools. A district, too, of popular dancing saloons. At No. 51 we see l’hôtel de Mortagne, built in 1711, where Vaucanson first exhibited his collection of mechanical instruments. Bequeathed to the State, that collection was the nucleus of the Conservatoire des Arts et Métiers: Arts and Crafts Institution (_see_ p. 64). Here the great mechanic died in 1782. No. 97, once a Benedictine convent, was subsequently a private mansion, then a factory, then in part a Protestant chapel. The École Maternelle at No. 99 was in past days a priory of “Bon Secours” (seventeenth century). No. 98 is on the site of a convent razed in 1906. There are remains of another convent at Nos. 100, 102. No. 161 was the famous “Maison de Santé,” owned by Robespierre’s friend Dr. Belhomme, to which he added the adjoining _hôtel_ of the marquis de Chabanais. There, during the Terror, he received prisoners as “paying guests.” His prices were enormous and on a rising scale ... the guests who could not pay at the required rate were turned adrift on the road to the guillotine. These walls sheltered the duchesse d’Orléans, the mother of Louis-Philippe, protected by her faithful friend known as comte de Folmon, in reality the deputé Rouzet, and many other notable persons of those troubled
