In 1929, Ludwig Mies van der Rohe and Lilly Reich design the German National Pavilion for the 1929 Barcelona International Exhibition. The official reception for the exhibition was held there, presided over by King Alfonso XIII and the German authorities. From then on, the story is well known to everyone. A symbolic work of the Modern Movement, the Pavilion has been extensively studied and interpreted, and has inspired the work of several generations of architects.
