query: What is the oldest building in Chicago?
passage: Henry B. Clarke House
Clarke House may have been modeled on the home of William B. Ogden.[3] The Clarke house is often described as the oldest surviving house in Chicago,[4] although part of the Noble-Seymour-Crippen House in the Norwood Park neighborhood was built in 1833. (However, Norwood Park was not annexed to Chicago until 1893.)[5] The Clarke House was designated a Chicago Landmark on October 14, 1970.[6] It was added to the National Register of Historic Places on May 6, 1971.
passage: Kenwood, Chicago
The southeastern portion of Kenwood contains the Indian Village neighborhood, which features the Chicago Landmark Powhatan Apartments and the National Register of Historic Places Narragansett. The 1902 Blackstone Library is another well-known landmark in the neighborhood. It continues to be part of the Chicago Public Library system. The recently reopened Hyde Park Art Center, located on Cornell Avenue just north of 51st Street and East Hyde Park Boulevard, is Chicago's oldest alternative exhibition space, with an on-site school and studio.
