The large gallery on the fifth floor devoted to Impressionism has been truly transformed. It has fallen to the architect Jean-Michel Wilmotte to modify the design of the museum, to improve the lighting and to re-examine the delicate dialogue between display cases and coloured walls. However, by choosing to leave the metal structures visible, the counterpoint with Victor Laloux's architecture of 1900 has been preserved.
There is dark wood flooring, and the walls are painted in a delicate grey allowing a full appreciation of all the chromatic nuances in the paintings, now enhanced by the new lighting system. The sculptures benefit from more discreet, well-spaced display cabinets.
