The Paris Observatory is located on three sites: Paris (Observatory Avenue) , Meudon and Nançay but communication around the three locations is not clearly identifiable as that group. The management of the institution decides to change its name and the Paris Observatory will now : «Great observatory» It was so we asked to redo the visual identity, the graphics, paper & the great observatory website, as well as displays of openness, the exposureand the exhibition catalog.
