Join us at Central Library with local historian Libby Cierzniak to learn how an ill-fated redevelopment plan led to the transformation of downtown Indianapolis, at the cost of entire neighborhoods and the displacement of more than 1,000 people.

Culture, History, and Society: Historic Indianapolis—In 1959, the Indianapolis Redevelopment Commission launched Project H, an ambitious plan to demolish more than 200 buildings in the heart of downtown Indianapolis and replace them with brand new apartment towers designed to lure high-income families and singles back to the decaying city center. But after 42 acres were cleared, the proposed apartment city failed to materialize. Join local historian Libby Cierzniak to learn how the ill-fated redevelopment plan eventually led to the transformation of downtown Indianapolis, but not before wiping out entire neighborhoods and displacing more than 1,000 people. 

Age Group: Adults

Location: This program will be held in person in the Indianapolis Special Collections Room (ISCR) on the 6th floor of the Central Library.
