The Stories of Slavery and Indigenous History in the Monuments of Harriet Tubman Square” from 1:30 p.m. to 2:30 p.m. for an illuminating talk about the various ways in which the park’s 18th- and 19th-century statues and monuments connect with stories of revolution, slavery, Black liberation, and Indigenous history.
