Beneath Chicago’s gleaming Cloud Gate lies the city’s most dramatic makeover. This episode traces Grant Park from marshland and post–Great Fire landfill to a soot-choked Illinois Central rail yard—and the century-long fight to keep the lakefront “forever open, clear and free.” We follow Daniel Burnham’s 1909 vision, Montgomery Ward’s lawsuits, and the philanthropists who turned coal dust into culture with Buckingham Fountain (1927) and a growing civic stage.

Then we jump to the 1990s deck-over that birthed Millennium Park: Frank Gehry’s Jay Pritzker Pavilion, Jaume Plensa’s Crown Fountain, and Anish Kapoor’s Cloud Gate—plus the hidden world beneath it all: Millennium Station, the Pedway, miles of garages, and relic freight tunnels. By the end, you’ll see why Chicago’s front yard is both a monument to beauty and a marvel of buried infrastructure.
