Monadnock Building: Building Tall in the 19th Century

In the late 19th Century, engineers were challenged to begin building taller structures with larger windows because of the rise in demand for office space in downtown Chicago. At the same time a method for producing steel inexpensively was discovered. These two events led to the development of a new structural design, the rigid metal frame. The invention of this technology is historically marked in the two halves of the Monadnock Building.
