What organization offers architectural tours in Chicago with over 300 volunteer docents?

The Chicago Architecture Center is renowned for its extensive architectural tours in Chicago, supported by a dedicated group of over 300 volunteer docents. These docents are trained to provide insightful commentary and in-depth knowledge about Chicago's rich architectural history and its iconic structures. The tours offered by the Center highlight not only notable buildings but also the evolution of the city’s architecture, showcasing styles from Gothic Revival to Modernism and beyond. This organization plays a vital role in promoting an understanding and appreciation of Chicago's architecture, making it an essential resource for both residents and visitors interested in the city’s architectural heritage.
