The Joseph Raphael De Lamar House is a mansion at 233 Madison Avenue at the corner of 37th Street in the Murray Hill neighborhood of Manhattan, New York City. The house, currently the Consulate General of Poland, New York City, was built in 1902–1905 and was designed by C. P. H. Gilbert in the Beaux-Arts style. The De Lamar Mansion marked a stark departure from Gilbert's traditional style of French Gothic architecture and was instead robustly Beaux-Arts, heavy with rusticated stonework, balconies, and a colossal mansard roof. The mansion is the largest in Murray Hill, and one of the most spectacular in the city; the interiors are as lavish as the exterior.

The Park Avenue main line, which consists of the Park Avenue Tunnel and the Park Avenue Viaduct, is a railroad line in the New York City borough of Manhattan, running entirely along Park Avenue. The line carries four tracks of the Metro-North Railroad as a tunnel from Grand Central Terminal at 42nd Street to a portal at 97th Street, where it rises to a viaduct north of 99th Street and continues over the Harlem River into the Bronx over the Park Avenue Bridge. During rush hours, Metro-North uses three of the four tracks in the peak direction.Originally constructed in the mid-19th century as a New York and Harlem Railroad route, the Park Avenue main line was initially a street railroad and ran to what is now Lower Manhattan. It was gradually truncated through the 1860s, until Grand Central Depot was opened at 42nd Street in 1871. The line was placed in a grade-separated structure in the late 19th century, as part of the Fourth Avenue and Park Avenue Improvement projects, and was electrified in the first decade of the 20th century as part of the construction of Grand Central Terminal. Since then, several improvement and rehabilitation projects have been made along the main line.

World Center for Women's Archives was an organization established by Rosika Schwimmer and Mary Ritter Beard in the hopes of creating an educational collection which women could consult to learn about the history of women. The center was located in the Biltmore Hotel at 41 Park Avenue in New York City. It closed in 1940, but the efforts made to establish a center to collect records encouraged several colleges and universities to begin develop similar archives of women's history. It was one of the earliest efforts to collect women's documents in the United States, predated the first accredited women's studies course in the U.S by 34 years, and preserved materials about women which otherwise might have been lost. It also redefined the way that historical documents were selected for archival inclusion. By changing what documents were noteworthy, using personal records to shape public history, the Women's Archive legacy was foundational to the development of feminist theory.
