49. The Metropolitan Museum of Art
City: New York
Address: 6 East 82nd St.
Though the Met has been around since the 19th century, it impacted the Complex Decade in a massive way in 2011, when the "Alexander McQueen: Savage Beauty" exhibition opened. Spanning his too-brief career—McQueen killed himself in 2010 at the age of 40—"Savage Beauty" generated enormous buzz (not to mention lines), attracting visitors from all walks of life. McQueen's work touched many of the artists that defined the Complex Decade; his work was touted by Rihanna, Kanye West, Lady Gaga, Katy Perry, and countless others.
