For the painter Edouard Detaille, the station was "superb and resembles a Palace of Fine Arts". Victor Laloux wanted to create “more comfortable and more luxurious spaces” than were found in traditional stations.
At the end of the competition, a team of three young architects from A.C.T. Architecture (Pierre Colboc, Renaud Bardon and Jean-Paul Philippon) were entrusted with the task of transforming the former station into a museum.
One of the museum’s innovations was to bring together all the artworks from a very short, but extremely productive period (1848-1914). Painting, sculpture, architecture, decorative arts and photography were displayed side by side.
