What's That Building? Margaret Burroughs Beach and 31st Street Harbor building

Landscaping along Lakeshore Drive almost completely hides the huge harbor building at 31st Street beach, which is big enough to store hundreds of cars and boats inside. For the final installment of a special summer series for What's That Building, Dennis Rodkin of Crain's Chicago Business tell us about remnants of the building’s past life during the World’s Fair and learn about its dark history and connection to the 1919 drowning of Eugene Williams as racial tensions exploded at a nearby beach.
