The Mies van der Rohe pavilion was designed in 1929 as the German pavilion for the International Exposition, and is an icon of modernist architecture. To top it all off van der Rohe also designed the iconic Barcelona chair to showcase here. The €5 entry price is a bit steep however, because the pavilion is much smaller than today’s standard wedding-cake brick veneer McMansion. Unless you’re an architecture tragic, it’s not a destination in and of itself; visit in conjunction with the MNAC or the Caixa Forum across the road.
