What the Brooklyn Academy of Music is to New Yorkers or the Barbican is to Londoners, the Onassis Cultural Center is to the Greek capital (actually it’s more). The stunning new building with a slatted facade opened in 2010—it covers an entire city block and in addition to the six above-ground floors are nine subterranean ones—the center offers remarkably international and ambitious programming in dance, theater, music, talks, visual arts, and even festivals. Interior theaters have fabulous acoustics, on the rooftop is a popular restaurant. The Onassis Foundation is behind it all (yes, it was the famous Aristotle Onassis who was once married to Jacqueline Bouvier Kennedy, but when Ari died in 1975, the foundation was renamed for his son Alexander).
