Most of its buildings are 12 to 18-story masonry apartment houses from the 1910s and 1920s, built to the building line and clad in brick with stone and terra cotta trim. Their designs draw on Italian Renaissance, Georgian, Jacobethan, Art Deco and Moderne styles. Architects represented include Delano & Aldrich, Emery Roth, J.E.R. Carpenter, Rosario Candela and George F. Pelham. The district also contains older and different buildings: row houses from 1856, a tenement from about 1895, the Lewis Morris and Reginald DeKoven houses, the George F. Baker complex, St. Ignatius Loyola Church and Park Avenue Christian Church. Planted median malls cover the railroad tracks that run north from Grand Central Terminal and have changed little since mid-century. The streetscape closely resembles its appearance around 1930. The period of significance runs from 1856 to 1961, and 70 buildings and the malls contribute to the district.","period_of_significance":"1856-1961","architect_builder":"Multiple architects and builders, including Delano & Aldrich, Emery Roth, J.E.R.
