One of the most original elements of the renovation of the building, which took place between 2015 and 2021, is the new glass skylight over the Courtyard of the Intendant, the entrance point for visitors. It was created by the architect Hugh Dutton, and is supported by a framework of steel weighing thirty-five tons. Its V-shaped ribs, of polished stainless steel, act as mirrors, which capture and redirect the light in the optimal direction. Though the entire opening is covered with ribs, they cast a minimum of shadows, due to their mirrored covering, and give the very heavy roof an appearance of lightness. The effect is enhanced by the use of glass made with purified iron oxide, which does not change color in the light. The diffusion of light is similar to that created by the facets of the pieces of crystal in the chandeliers of the 18th century.
