| The work of 20th-century American architect Louis Sullivan was influenced by the movement known as Art Nouveau. This picture shows the front facade of the Carson Pirie Scott department store in Chicago, designed by Sullivan and completed in 1904. The elaborately decorative cast iron is characteristic of the architect’s love of detail. Above the first two floors, the design of the remaining twelve is a contrast in simplicity, with geometric windows evenly spaced within the structural steel skeleton. |
