Emerging from a concrete courtyard a block south of New York City’s Central Park is one of the most recognizable pieces of Apple’s corporate identity. A steel-and-glass cube, designed by architecture firm Bohlin Cywinski Jackson and erected in 2006, has been a fixture of Manhattan’s tourist circuit since it arrived on a heavily trafficked block along Fifth Avenue. Beneath it, housed in the basement of the General Motors building, was the world’s only 24-hour Apple store.
