Factories used by Clément-Bayard In 1894 he started construction work on a former military site in the Faubourg Saint-Julien at Mézières, to build a new factory, which would become known as La Macérienne. Clément personally supervised the work remotely using photographs taken every day and visiting the site once a week. By 1897 it was producing components and spokes for the Gladiator Cycle Company. It covered 15,000 m2 and using a hydraulic turbine power plant, a steam room, large machine hall, a foundry, a workshop for the nickel processing, the operation with the manufacturing of nuts and spokes on a bike. The factory building still exists but in the spring of 2006 it was transformed into a cultural center. Clement-Bayard Automobiles was situated at the Boulevard de la Saussaye 57 in Neuilly in west Paris. Between 1899 and 1922, three wheelers and cars were built there. Shortly after the purchase of Gladiator cycles in 1896 Adolfe Clément began to build the new factory at Levallois-Perret in north west Paris. This produced cycles and various cars from 1898, (Clément-Panhard, Clément-Gladiator from 1901, Clément-Bayard from 1903), and went on to build various Citroën models including the Citroën 2CV for nearly forty years from 1948 to 1988. From August 1914 it was dedicated to wartime production. In 1908 'Astra Clément-Bayard' began manufacturing airships at a new factory in La Motte-Breuil. War activity Adolphe Clément ceded control of Clément-Bayard to his son Maurice in early 1914, but the consequences of World War I for the company were disastrous. The La Macérienne factory at Mézières was lost to the Germans, the machinery was shipped back to Germany, and the forges, foundries and smelter were destroyed. The gutted building was used as an indoor riding school for German officers. Automobile production at Levallois-Perret in Paris was suspended in August 1914 and the factory was turned over to war production, military equipment and military vehicles, aero engines, airships and planes.
