This museum was created during the renovation of the États-Unis neighbourhood in the 1980s and 1990s, and the inhabitants were strongly involved in the project. The museum comprises a recreated apartment of the 1930s, which shows how life was like in these very modern housing units, and the 25 wall paintings depicting Garnier's work and ideals. You can also see the walls on your own but you will miss the interesting comments on the history of the area and the social project behind it.
