Wild Onions: A Brief Guide to Landmarks and Lesser-Known Structures in Chicago’s Loop

Wild Onions: A Brief Guide to Landmarks and Lesser-Known Structures in Chicago’s Loop offers information about the history and architectural design of more than 175 buildings in downtown Chicago, including iconic structures as well as often-overlooked examples of the city’s distinctive architecture. The guide was originally prepared for attendees at the APT annual conference in Chicago in 1989, and has been updated twice since original publication. The current (2014) edition includes archival images as well as photographs by noted Chicago architectural photographer Leslie Schwartz. Wild Onions is a useful pocket guide to architecture in the central city, and a good overview of Chicago’s history and buildings for reference during a self-guided walking tour (map included), in person or in virtual format.
