Another key example of SOM's modernist legacy is found in Colorado Springs, Colorado, where SOM master-planned a campus for the U.S. Air Force Academy. Built between 1958 and 1968, the campus broke from the traditions of West Point and Annapolis to become the first U.S. military academy designed in the modern style. The centerpiece of the campus is the Cadet Chapel, designed by architect Walter Netsch. The American Institute of Architects awarded the building with its prestigious Twenty-five Year Award, conferred on architectural works of enduring significance.
