These are maps of buildings described in several books documenting Chicago’s architecture, especially commercial buildings downtown

• Chicago School of Architecture by Carl W. Condit
• Chicago 1910-1929 by Carl W. Condit
• Chicago Skyscrapers 1871-1934 by Thomas Leslie
• AIA Guide to Chicago ed. by Laurie M. Petersen

In each, buildings can be filtered by the decade of construction (click on menu at top right), and buildings that have been demolished are shown in red (except for the AIA book).
