River Farms to Urban Towers
— Southwest Heritage Trail —This high ground serves as a monument to Benjamin Banneker, a free African American who charted the stars for the first survey of Washington, DC. Banneker was 60 years old when he hired on to assist surveyor Andrew Ellicott. A tobacco planter from Baltimore County, Maryland, Banneker had taught himself mathematics and astronomy. With these skills, he observed the stars' movements each night. Ellicott used Banneker's calculations to determine the District's boundaries. In addition, Banneker published a series of almanacs predicting the movements of the sun, moon, and stars to guide farmers in the best timing for planting and harvesting.
