The 10th edition of the Architecture Biennial has just opened at the Giardini and the Arsenale. This year's theme is about Cities, Architecture and Society. It is curated by Richard Burdett. I almost visited every pavillion and the Arsenale. One of the main aspects of this biennial is a sparse ideas of proposals and a vast presentation of information (overpopulated cities, migration etc). Ideas that I have seen 3 years ago when Rem Koolhaas was the guest editor of Wired. Of course there are some highlights. The French pavillion was one of them. The project was called Metavilla in which a team of people did a sort of a squat in the pavillion building a temporary block of rooms. The Austrian pavillion which one of it's projects was the Aircraft Carrier City by Hans Hollein made in 1964. An aircrfat dugged in a rural area creating a new city.
