Just off Union Square, the Xanadu Gallery, opened in 1979, is housed in the city’s only Frank Lloyd Wright-designed building. Behind the walls of geometric brickwork, visitors will find an impressive collection of antiquities, jewelry, and artwork from Africa, Asia, Oceania, and Latin America. Whether you’re looking to expand your own collection, or just defending your reputation as a true culture vulture, the gallery is the perfect location to get your fix.
