The Venice Biennale is staged in an enormous old Arsenal building and in an urban park a few blocks away that houses 30 national pavilions. The first of these pavilions opened in 1907 and several were designed by famous architects like Josef Hoffmann (Austria), BBPR (Canada), Alvar Aalto (Finland), and Sverre Fehn (Nordic). The United States pavilion was designed by William Adams Delano. There have been very few buildings built in the garden since James Sterling designed the biennial book store in 1991, but just behind the U.S. pavilion the Australians are building a new exhibition space designed by Denton Corker Marshall. The Australian architects describe the pavilion as a simple structure or “a white box contained within a black box.” The pavilion will open in 2015 for the 56th art biennale and its $6 million price tag will be paid for with private funds.
