I've published several shots recently of this old factory. I love the steel work in it. And for good reason. It was designed by Gustave Eiffel for the Universal Exposition of 1900 and installed in the Bois de Vincennes (one of the two great wooded parks) in Paris. Its vast open space served as a hanger for dirigibles on display. After the exposition, it was dismantled and taken by train to Amboise to be used in a metal fabrication business. In 1940, it was converted to auto manufacturing.
