Manuelle Gautrand's architectural extension is like a hand wrapped around the original building, designed by Roland Simounet in 1983, and doubles the exhibition space. Inside and in the sculpture park, LaM presents, in particular, early 20C works of modern art from the Donation Geneviève and Jean Masurel, pieces of contemporary art and a unique Art Brut collection. Work by Calder, Picasso, Léger, Klee, Kandinsky, Soulages, Messager, Corbaz, Darger... to name but a few.
