Les Gratte-Ciel de Villeurbanne. Mayor Lazare Goujon (elected 1924) engaged the city in a vast public works initiative. Arguably the most visible heritage of this program is the Gratte-Ciel, a housing complex made up of two Art Deco towers and annex smaller buildings, lining up along the Avenue Henri Barbusse. These structures are the work of architect Môrice Leroux, and one of the most notable Art Deco structures in France. Having undergone thorough renovation, the 19-story twin towers have become an emblem of the city.
