If you love seeing historic images of Chicago and learning more about its history from the late 1800s on, Errol Magidson reveals the history of a treasure buried on Chicago's far Southwest Side. Few people beyond the neighborhood seem to be aware of its existence. Five keepers of the Castle tell compelling stories against the backdrop of Chicago’s rich history, including the Great Chicago Fire of 1871, the World’s Columbian Exposition of 1893, the cable-car era, the dawn of the automobile, the Century of Progress International Exposition of 1933-34, World War II, and the Civil Rights Movement.
