Cincinnati's Contemporary Arts Center is the first built project in theUnited States by celebrated London-based architect Zaha Hadid. More than another example of the "Bilbao Effect" - the "build it and they will come" attitude that so many cities have taken on after the success of Gehry's building in Bilbao - the CAC is simply the latest building in a long line of projects that the city of Cincinnati has taken on over the last ten years, including works by Peter Eisenman, Frank Gehry and Michael Graves.
