Bourgeois' teams restored the glazed flat-tile roofs of the domes of the castle built on the banks of the Rhône in the 2024th and XNUMXth centuries. The varnish shades were custom-made to match the roof colours used at the time, and the bell towers and decorative elements (bull's eye, ventilation oculi and fire pots) were replaced with new ones, in pre-patinated anthracite zinc. The central body will be restored from spring XNUMX.
