Frank Lloyd Wright's tower in Racine, Wisconsin

One of the most unusual creations of  Frank Lloyd Wright can be seen in Racine, Wisconsin. A 1950 vertical expansion of the 1939 S.C. Johnson and Son, Inc office center. This cantilever structure has a 153 foot outer shell of specially kilned brick bands and glittering Pyrex glass tubing laid horizontally like logs and chinked with synthetic rubber. Its heart is a central concrete pillar from which the floors, alternately square and circular, cantilever out without support from walls.
