Location: Minneapolis, MN
Architect: Jean Nouvel
Year: 2006

Jean Nouvel, famed French architect, gave the Twin Cities the gift of the "Best Cultural Space in the USA" and one of the "10 most important buildings of the 21st-century." Bare in mind, the century still has roughly 90 years left, but you can still get a sense of the legacy the Guthrie Theater has already built for itself in just 5 short years.
