The Board of Trade was founded in 1848 to regulate trade of the Midwest's bountiful agricultural commodities. This outstanding Art Deco skyscraper (1930, Holabird & Root) testifies to that abundance, anchoring the south end of the LaSalle Street financial district. Ceres, the goddess of the harvest, gazes down from high atop the building's soaring roof. Today all the action takes place inside on the 60,000-square-foot trading floors, where frenetic traders in brightly colored jackets buy and sell stock options and commodities.
