This sky of about twenty square meters, apparently classic and appropriate in this castle, reveals a starry sky and its milky voice at night when the room is plunged into darkness. This principle of double decoration is innovative. Once the sky was "daytime", photoluminescent particles were projected so that by taking on UV during the day, they could radiate and redistribute their light at night. The 4-metre high room does not allow the dry droplets to be seen in relief from the particles. Photoluminescent strips on the walls are complementary (to see in the curiosities)
