When the Barcelona Pavilion was designed in 1929 for the Barcelona International Exhibition, it wasn’t built to last. The gorgeous modernist structure with its refined glass and marble stoa was merely created for the exhibition as a temporary building and was taken down within a year. Its architect, the revered Mies van der Rose left no blueprint. Work began on rebuilding the Pavilion in 1983 with the photographs and drawings that remained. It took three years complete and now it celebrates it’s 30th anniversary.
