The Van Ness Mansion was completed for John Peter Van Ness and Marcia Van Ness in 1816 by Benjamin Henry Latrobe on 17th Street, Washington, D.C. They entertained the Madisons, James Monroe, George Washington Parke Custis and John Tayloe III at their mansion. The mansion was described as the "finest house in America". It was built on land that had been owned by Marcia's father, David Burnes, who left 500 acres along the Potomac River to Van Ness. It was one of the most expensive houses in the country, fit with hot and cold running water, a modern feature at the time, and the mansion was the first residence in the city to have that luxury. Latrobe added a feature designed to maintain a sense of privacy when food was conveyed to dining rooms. Servants accessed rotating servers from a hallway that allowed them to deliver food without entering the room. He installed them previously at the Adena Mansion in Chillicothe, Ohio. It had the country's largest and coolest wine vault. Latrop said that the Van Ness Mansion was "the best house I ever designed". It overlaid his "American rational-configuration on the kind of English residential model that impressed him during his work for and study with S. P. Cockerell."Latrobe also worked with John Peter Van Ness on the reconstruction of Washington, D.C. public buildings. Van Ness was a commissioner of the Capitol reconstruction commission, along with Richard B. Lee and Tench Ringgold. The mansion degraded over time. In 1907, the mansion was razed and the Pan American Union Building was built on the site. The stables, also designed by Latrobe, were not demolished at that time. The stuccoed building existed was located at 18th and C Streets.

Art Museum of the Americas (AMA), located in Washington, D.C., is the first art museum in the United States primarily devoted to exhibiting works of modern and contemporary art from Latin America and the Caribbean. The museum was formally established in 1976 by the Organization of American States (OAS) as the Museum of Modern Art of Latin America. Artists represented in the AMA's permanent collection include Carlos Cruz-Diez, Candido Portinari, Pedro Figari, Fernando de Szyszlo, Amelia Peláez, and Alejandro Obregón. The art collection of the OAS was initiated under the organization's Visual Arts Unit, beginning with the first donated artwork by the Brazilian neo-realist artist Portinari, in 1949. In the following decade the Permanent Council of the OAS determined to establish an acquisitions fund, in order to build up a permanent collection of artworks by significant contemporary artists from the member states of the OAS. A number of works were also purchased from or donated directly by artists, after the temporary exhibitions periodically held at the OAS gallery. The Art Museum of the Americas itself was established in 1976 by OAS Permanent Council resolution, on the occasion of the United States Bicentennial. The museum opened in what was formerly the official residence of the OAS Secretary General, a Spanish Colonial-style structure designed in 1912 by the architect Paul Cret. Initially the permanent collection held some 250 artworks, expanding over the next quarter-century to over 2000 items of painting, sculpture, installations, photography, and drawing, from the early 20th century and onwards. In addition to its permanent collection of mainly Caribbean and Latin American art, AMA hosts temporary and special exhibitions from across the region, and provides educational seminars and lectures from invited speakers. The Art Museum of the Americas has also expanded its programs to include evening events, such as Art After Dark, with cutting edge music, video, performance, and installation art.
