MAD.Co - Museo di Arte Diffusa di Collegno (Museum of Diffuse Art of Collegno) is a dissemination project created with the aim of enhancing and disseminating knowledge of the vast public heritage of contemporary works of art in the city’s territory, which unfold along a veritable open-air exhibition route. The collection, which is being implemented and constantly developed, includes numerous contemporary works such as sculptures, frescoes by well-known artists - for example Mario Merz - and Street Art murals: it has been progressively built up over time from 1977 onwards, when the wall was demolished and the asylum dismantled.
