Originally a school textbook depository, this building was the site from which Lee Harvey Oswald fired shots killing President John F. Kennedy, Jr. on November 22, 1963. Though intensive investigations decided that Oswald acted alone, many conspiracy theorists disagree, and continue to assert the involvement of shooters from a nearby "grassy knoll." The first five floors of this building are used as office space, but the sixth and seventh floors are open to the public as a museum dedicated to the assassination.
