Circular lane located between the underground lines and Boulevards des Maréchaux. Located entirely in the 15th arrondissement. It extends into the streets of Vouillé. Hosts a portion of the bus line 62. 170, Rue de la Convention: Paul Legriel here seems to have started his career as an architect. It seems to have been sufficiently proud of this first effort to have signed a fairly visionary. Its sponsor, widow C. Vacquant, did publish a request for authorization to build on January 30, 1900. Apparently, she found very satisfied with its investment and its architect, since it started before December 5, 1900, the building adjacent to the No. 168. At that time, she already lived at 170, Rue de la Convention, a sign that the building itself had lasted less than a year.
