 The concept for the Magnificent Mile was part of the 1909 Burnham Plan of Chicago. It was constructed during the 1920s to replace Pine Street, which had been lined with factories and warehouses near the river, and fine mansion and rowhouse residences farther north. The earliest building constructions varied in style, but challenged new heights in construction. The name the "Magnificent Mile" is a registered trademark of the Greater North Michigan Avenue Association (GNMAA).
