The Barcelona Pavilion
This pavilion, designed by German architect Ludwig Mies van der Rohe for the 1929 International Exposition in Barcelona, is considered one of the most influential modernist buildings of the 20th century. The simple geometric structure realized in extravagant marble, red onyx, and travertine, and with two reflecting pools, has inspired countless homes and art galleries. The iconic Barcelona chair was also designed specifically for the building. The pavilion is located just below the National Museum of Catalan Art in Montjuïc Park and doesn’t take long to visit, but to truly appreciate Mies van der Rohe’s genius, book an architecture tour with a modern architecture expert. Tours from $100.
