I'd seen and admired the work of Ferdinand Fillod online, and wanted to see it personally, but this proved hard work, and in spite of having pored over maps, using the smartphone when we reached the area, etc, there seemed to be no way we could find the famous five prefabricated metal pavilions. However, I asked a guy who was gardening nearby and although he'd not heard of the structures about a kilometer from his house, nor La Rue de la Paix on which they stand, he knew the Rue de Bruxelles which they're (almost) on the corner of, we had a brilliant lead.
Fillod is seen as a pioneer in the prefabricated building field, and these in Gueugnon were built in the 1930s and have served several purposes. They were a response to a temporary housing crisis among forge workers, they served as a prison for German soldiers, they have been used for sports and general cultural use, and these five are now monuments historiques.
