Mies van der Rohe
The German Pavilion for the 1929 Barcelona International Exhibition, this is the building that spawned THAT column and THOSE chairs. It was demolished in 1930 but a replica was built in the 1980's. Normally I wouldn't endorse a replica but... I photographed it again this year with the category winners and jurors of this years World Architecture Festival enjoying cocktails and canapes poolside. As you would!
