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.

Glisten

Glisten (until February 2026 GLSEN; originally, Gay, Lesbian & Straight Education Network) is an American education organization working to end discrimination, harassment, and bullying based on sexual orientation, gender identity and gender expression and to prompt LGBTQ cultural inclusion and awareness in K-12 schools. Founded in 1990 in Boston, Massachusetts, the organization is now headquartered in New York City and has an office of public policy based in Washington, D.C. As of 2026, there are 15 Glisten chapters across 13 states that train about 1,000 students, educators, and school personnel each year.The chapters also support more than 4,000 registered school-based clubs—commonly known as gay–straight alliances (GSAs)—which work to address name-calling, bullying, and harassment in their schools. Glisten also sponsors and participates in a host of annual "Days of Action", including a No Name-Calling Week every January, a Day of Silence every April, and an Ally Week every September. Guided by research such as its National School Climate Survey, GLSEN has developed resources, lesson plans, classroom materials, and professional development programs for teachers on how to support LGBTQ students. Research shows that in response to bullying and mistreatment, many LGBTQ students avoid school altogether; this can lead to academic failure. To combat this problem, Glisten has advocated for LGBTQ-inclusive anti-bullying laws and policies. Glisten has also worked with the U.S. Departments of Education, Justice, and Health and Human Services to create model policies that support LGBTQ students and educators. Glisten has considered their signature legislation to be the Safe Schools Improvement Act and has been honored by the White House as a "Champion of Change".

Morgan Library & Museum

The Morgan Library & Museum, formerly the Pierpont Morgan Library, is a museum and research library in the Murray Hill neighborhood of Manhattan in New York City. It is situated at 225 Madison Avenue, between 36th Street to the south and 37th Street to the north. The Morgan Library & Museum is composed of several structures. The main building was designed by Charles McKim of the firm of McKim, Mead and White, with an annex designed by Benjamin Wistar Morris. A 19th-century Italianate brownstone house at 231 Madison Avenue, built by Isaac Newton Phelps, is also part of the grounds. The museum and library also contains a glass entrance building designed by Renzo Piano and Beyer Blinder Belle. The main building and its interior is a New York City designated landmark and a National Historic Landmark, while the house at 231 Madison Avenue is a New York City landmark. The site was formerly occupied by residences of the Phelps family, one of which banker J. P. Morgan had purchased in 1880. The Morgan Library was founded in 1906 to house Morgan's private library, which included manuscripts and printed books, as well as his collection of prints and drawings. The main building was constructed between 1902 and 1906 for $1.2 million. The library was made a public institution in 1924 by J. P. Morgan's son John Pierpont Morgan Jr., in accordance with his father's will, and the annex was constructed in 1928. The glass entrance building was added when Morgan Library & Museum was renovated in 2006.
