In the early stages of planning for the Museum’s centennial birthday, another major expansion was proposed and accepted. In 1994, based upon his international vision and skill as an engineer and architect, Spanish-born architect Santiago Calatrava was chosen to be the designer to carry the Museum into the next millennium. On December 10, 1997, the Milwaukee Art Museum broke ground for the new addition.
The Quadracci Pavilion, the first Calatrava-designed building to be completed in the United States, opened in 2001 to rave reviews. The expansion project included new exhibition galleries and an auditorium, as well as a museum store and cafe. In addition, the Museum completely renovated and remodeled its Collection galleries.
