The interior design of the museum was first conceived by a team of scenographers and architects directed by Gae Aulenti. With Italo Rota, Piero Castiglioni (lighting consultant) and Richard Peduzzi (architectural consultant), Gae Aulenti succeeded in creating a unified presentation within a large diversity of volumes, in particular by using a homogeneous stone covering for the floors and walls. This installation brings the large space of the former station down to size.
The signpost system was conceived by B. Monguzzi and J. Widmer. As for the lighting, both natural and artificial light is used, in order to create the variations in intensity needed for the different works of art presented.
