As previously illustrated, the national mobilization to provide hospital spaces for the masses of French military wounded during World War I led to the creation of several hundred “hopitaux auxiliaires.” One of the institutions re-purposed as “hoptital auxiliaire #88” from 1914-1916 was the “country” home of the Lazaristes of the maison-mere in Paris. The house at Gentilly (a commune in the suburbs south of Paris) was located in the country during the 19th century but gradually was engulfed by the urbanization of Paris into the 20th century, and eventually torn down for modern road construction.
