It was designed by Albert Ten Eyck Brown and built between 1931 and 1933 as a Public Works Administration project.","why_significant":"The building is argued to be significant under Criterion C as an excellent example of Modern Classic architecture with Art Deco detailing, and one of Atlanta's finest federal buildings of the era. It also served as the central postal facility for the southeastern United States, and its location opposite Terminal Station allowed mail to move by rail through connecting tunnels.","narrative":"Rising ten stories on a 2.4-acre block in downtown Atlanta, this post office annex was built between 1931 and 1933 as a Public Works Administration project. Architect Albert Ten Eyck Brown designed it to handle mail sorting and distribution as well as public postal service. Its stepped, blocky form is clad in granite and marble, with smooth walls and restrained Art Deco ornament, including nickel-alloy entrance panels showing eagles and a shield. Inside, the east lobby has Tennessee, Vermont and York Fossil marble and nickel-alloy fittings. The site faced Terminal Station, and tunnels carried mail between the two by conveyor, making the building the central postal facility for the southeastern United States. It is regarded as one of Atlanta's finest examples of 1930s federal architecture in the Modern Classic style. The Postal Service left in 1980, and the General Services Administration acquired the building in 1981 for federal offices, which remain its use.","period_of_significance":null,"architect_builder":"Albert Ten Eyck Brown, with associates Alfredo Barili, Jr. and J.
