1847
Nicolas-Philibert Guinon refined dyeing silk plain yellow using picric acid, the first synthetic organic dyestuff discovered in the world.
The Guinon family made the Domaine du Convert (the name of the hamlet) their holiday home. At that time, the manor house, that is still standing today, neighboured the vinegrower-winemaker’s house (that stood where the Château stands today).
Construction of the château started at this time.
