The sculptor, Tony Rosenthal, discusses the idea behind his popular rotatable sculpture, Alamo, located in Astor Place at E 8th Street. The Alamo, a 15-foot tall cube, is more commonly referred to as the "Astor Place Cube." It was installed as part of Doris C. Freedman's "Sculpture in Environment" project, and was the first permanent contemporary outdoor art sculpture installed in New York City. According to scholars Edward Ablee and Sam Hunter, employing the outdoor cube established Rosenthal as a "master of monumental public sculpture." The cube is poised on its tip, and can be physically rotated by passers-by.
