The Noble-Seymour-Crippen House is a mansion located at 5624 North Newark Avenue in Chicago's Norwood Parkcommunity area. Its southern wing, built in 1833, is widely considered the oldest existing building in Chicago.
The southern wing of the mansion was originally used as a farmhouse by Mark Noble, Sr., an English immigrant. In 1868, Thomas Hartley Seymour of the Chicago Board of Trade purchased the house and surrounding land, adding an Italianate style northern wing to accommodate his large family and their servants. The family lived at the site until 1916, when they sold it to Stuart and Charlotte Allen Crippen, a concert pianist and an actress. During the 1920s, the Crippens installed indoor plumbing and electricity and added a second stairway to the Noble wing. The Crippen children and grandchildren sold the building to the Norwood Park Historical Society in 1987.
