It was the Brooklyn terminal of the IRT Contract 2 extension and later a major hub linked to the Long Island Rail Road and BMT. It retains a high degree of integrity and fine decorative detail.","narrative":"Beneath the meeting of Flatbush, Atlantic and Fourth Avenues in downtown Brooklyn lies a subway complex built in two stages. The IRT station opened in 1908 as the terminal of the Contract 2 extension into Brooklyn, and the BMT station followed in 1920. William Barclay Parsons handled the engineering, using cut-and-cover construction, while Heins & LaFarge designed the architecture and decoration. Surviving details include pink marble wainscot, white glass tile, terra cotta friezes, mosaic name tablets and faience plaques showing the letter \"A\" with tulips. The BMT platform has its own mosaic bands and lettered plaques. A restored control house on a traffic island is the most visible surface element. For twelve years the station ended the IRT line in Brooklyn and linked the subway to the Long Island Rail Road, making it a major transfer point. It was listed for its role in transportation and Brooklyn's growth and for its engineering and artistic quality, despite later alterations to concourses and entrances.","period_of_significance":"1908-1920","architect_builder":"Parsons, William Barclay (engineer); Heins, George L. and LaFarge, Christopher G.
