On the occasion of the thirtieth anniversary of the reconstruction of the Barcelona Pavilion, the Fundació Mies van der Rohe has organised a symposium, presided over by Juan José Lahuerta, on the figure of Mies van der Rohe and the German Pavilion for the 1929 Barcelona International Exhibition. For this event, several experts on Mies van der Rohe, his work and, in particular, the Pavilion have been convened to present the results of their latest research. The sessions will be held on October 13, 14 and 15 at the Barcelona CaixaForum and will constitute a point of encounter for discussions and knowledge exchange.
