The MEN is well know for its museology of the rupture (muséololgie de la rupture), initiated by in the 1980's. This exhibition policy aims at questioning the objects' meaning and the museum's social role. Starting in 2015, major renovations were undertaken on the museum's buildings. The historical part was renovated first, followed by the temporary exhibitions building, ending in 2020. Since 2017, the reference exhibition is L'impermanence des choses, centered on the museum's collections.
