Dive into the Hypnotic World of Op Art

Wear sunglasses and get clearance from your psychiatrist before wading into the interlocking, honeycomblike galleries of the Fondation Vasarely. Opened in the '70s by Victor Vasarely, the Hungarian- born mastermind of the Op Art movement, this retro-futuristic museum is packed with soaring, kaleidoscopic and mind-bending geometric art that will blow out your retinas and sizzle your brain - think M. C. Escher abstractions on a cathedral scale. The 7-euro admission fee includes a free audio guide.
