It contains 393 contributing buildings, mostly late nineteenth-century rowhouses.","why_significant":"The nomination argues the original district's boundaries were arbitrary and that the expansion area shares the same historical development, architects, developers, styles and residents. With the additions, the district forms a cohesive unit of late nineteenth-century rowhouses, apartment buildings and institutions in Harlem.","narrative":"This Harlem district expansion adds about four blocks to the existing Mount Morris Park Historic District, bringing it to roughly 15 blocks. The largest addition lies west of the original area, running from West 118th to West 123rd Street between Lenox Avenue and Adam Clayton Powell Jr. Boulevard. Smaller additions lie at Fifth Avenue and to the north around West and East 124th Street. It includes 393 contributing buildings, mostly three- to five-story rowhouses built from the late 1870s through the 1890s in Neo-Grec, Queen Anne, Romanesque Revival and Neo-Renaissance styles, many fronted in brownstone. Apartment buildings, often Beaux-Arts in design, stand at corners and along the avenues. The earliest buildings are Italianate and Second Empire rows from 1868 and 1870. The nomination holds that the original boundaries were drawn arbitrarily, and that the added blocks share the same developers, architects, styles and early residents, so the enlarged district reads as one cohesive neighborhood.","period_of_significance":null,"architect_builder":"Many architects and builders, including Neville & Bagge, John Hauser, Alfred H.
