The great Museomix adventure began in Paris in 2011 at the Arts Décoratifs Museum. For its 2015 edition, the Ile de France community offers a new challenge: to invest a place dedicated to scientific culture, The City of Sciences and Industry. For the first time a space dedicated to young audiences, the Children’s City, will be remixed and the library, which is being transformed into a “Living Center”, will be one of the playgrounds opened to the museomixers.
