Now that the pavilions have begun arriving at the Grand Canal, that other great architectural exhibition of the summer has faded into memory. No, we’re not talking about the one in Pasadena. Or at P.S.1. Not the Serpentine. This would be the Shanghai World Expo, which did have some pretty great pavilions upon its opening in June. Not among them, sadly, was the U.S. Pavilion, in large part because we refused to front the money for the structure, and so it got farmed out. Now, Marketplace has a report from the pavilion that pretty perfectly encapsulates the problems and perseverance of the little pavilion that couldn’t, even how it has won over many Chinese, what with their love with propaganda and irony.
