The Anacostia Historic District is a historic district in the city of Washington, D.C., comprising approximately 20 squares and about 550 buildings built between 1854 and 1930. The Anacostia Historic District was added to the National Register of Historic Places in 1978. "The architectural character of the Anacostia area is unique in Washington. Nowhere else in the District of Columbia does there exist such a collection of late-19th and early-20th century small-scale frame and brick working-class housing."
