Barcelona Pavilion - Mies van der Rohe
The Barcelona Pavilion, designed by Ludwig Mies van der Rohe, was the German Pavilion for the 1929 International Exposition in Barcelona, Spain. It was an important building in the history of modern architecture, known for its simple form and extravagant materials, such as marble and travertine. Because this was planned as an exhibition pavilion, it was intended to exist only temporarily. The building was torn down in early 1930, not even a year after it was completed. However, thanks to black and white photos and original plans, a group of Spanish architects reconstructed the pavilion permanently between 1983 and 1986.
I'm very glad they did, as it's bloody amazing!
