In the Provence village of Lacoste (nothing to do with the clothing brand) there was a Flour Miller on the plateau behind Chateau de Sade, now owned by Monsieur Pierre Cardin the Parisian couturier.
In 1889, Louis Malachier, walked from Lacoste to Paris (and back) to see the unveiling of La Tour Eiffel.
According to a local historian, it was tantamount to treason, leaving the helm of his windmill and not producing farine pour des baguettes.
