The nominated portion is the curved granite headhouse, with remnants of its brick wings.","why_significant":"The nomination argues the terminal was a major innovation in station planning, with a prototypical double-decker track system that put suburban subway and electric lines below long-distance tracks. It was the largest and quickly the busiest passenger station in the country. It is also Boston's first and only remaining monumental public example of Neo-classical Revival architecture, and its clock mechanism is the largest of its kind in New England.","narrative":"South Station Headhouse is the surviving front of a large railroad terminal at Atlantic Avenue and Summer Street in Boston. The Boston Terminal Company, formed in 1896 by the railroads serving the south side of the city, built it between 1897 and 1899. Shepley, Rutan, and Coolidge designed it, and Norcross Brothers constructed it. A curved granite headhouse with a portico of paired Ionic columns, a clock topped by an eagle, and three round-arched entrances anchors the design. Brick wings once ran along both streets. The terminal introduced a double-decker track layout, with suburban subway and electric lines below long-distance tracks, and became the busiest station in the country. Its Neo-classical Revival style was Boston's first monumental public example. The metal train shed was demolished in 1930, and urban renewal plans called for removing the remaining wings, leaving the headhouse as a gateway to a new transportation center.","period_of_significance":"1896-1899","architect_builder":"Shepley, Rutan, and Coolidge (spelled \"Codidge\" in the form); built by Norcross Brothers; train shed engineer J. Worcester","architectural_style":"Neo-classical Revival","criteria":[],"status_note":"Rated good condition and altered; the headhouse remains externally intact while the train shed and parts of the wings were demolished. Remaining wings were slated for demolition under the South Station Urban Renewal Project.
