Light test in Arc and Senans

The lighting of the Saline is designed to highlight the different buildings. They will therefore be highlighted by projectors generally recessed into the ground diffusing intermediate white light of 3000 K, with a CRI of 85/90.


The lighting of the Saline is designed to highlight the various buildings listed as UNESCO world heritage sites since 1985. We have selected lighting devices that correspond to this lighting by considering photometry, technique, aesthetics and financial cost. And we relied on the study by Dominique Massounie of November 13, 2022, (lecturer at Paris-Nanterre), entitled “How to light the Royal Saltworks – What Ledoux says about the relationship of its architecture to light”.


Le Point Lumineux agency, assisted by the Eiffage company, carried out several Lighting tests at the Royal Saltworks of Arc et Senans in the presence of the Project Owner. Some adjustments remain to be made, but the results are satisfactory. The installation will be received at the beginning of November.
