The MUS traces the history of Suresnes, its urban landscape and its economic and social evolution. It particularly highlights the social urbanism of the years 1920-1940 and aims to transcend this local dimension by inscribing it in the political and social history of the interwar period.
The permanent collections make it possible to better know the thought and the action of Henri Sellier, political leader at the head of the General Council and the Office of Cheap Housing in the Seine department and Minister of Public Health from 1936 to 1937. Through his vision of the city and his achievements both in Suresnes and in the Paris metropolitan area, this personality is a prominent figure and founder of social urbanism and the promoter of what was already called the «Grand Paris».
