Since 1998, Olivier Menanteau has set up the production of visual ensembles in places as different as a suburban secondary school in Grenoble (Collège Vercors, Le Magasin, 1998) or C.E.U. (Centros Educacionais Unificados, 2004) just outside Sao Paulo. These schemes are a seach into the visible marks of conflicts in the world of work, education health, and science. From 2006 on, the Mediagenic projects take place in UNO (Media Alert New York, 2006), in Vilnius, Lithuania, with president Dalia Grybauskaite, in Phnom-Penh, Cambodia, in Paris, Marseilles and Berlin. They deal with the links between the event and history. His last works, done in 2017-2018 in the Fiji islands, in Greece and in the Centre of Interpretation of Architecture and Heritage in Saint-Laurent-du-Maroni in Guyana, try to show how individual memory melts into history.
