Mies van der Rohe’s famous and often-reproduced Barcelona Pavilion, built for the 1928 World’s Fair–then demolished in 1930 and reconstructed as a permanent installation in 1986–was an important building in the history of modern architecture. Known for its simple form and extravagant materials, such as marble and travertine, the Pavilion stood on a large podium alongside a pool. With its perpendicular planes that seemed to shoot out into three-dimensional space, it was considered an instant milestone for both architecture and design. (Mies created his famous Barcelona Chair to go inside of it.) According to the architect, the Pavilion also represented an equally important milestone in the joining of art and architecture, for its open-plan, “flowing space” provided the ideal environment for the display of the artwork by sculptor Georg Kolbe. The outcome of this collaboration was monumental for both artists, who went on to work together again, as well as with other collaborators in both fields.
