Henry B. Clarke House
Clarke House may have been modeled on the home of William B. Ogden. The Clarke house is often described as the oldest surviving house in Chicago, 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.) The Clarke House was designated a Chicago Landmark on October 14, 1970. It was added to the National Register of Historic Places on May 6, 1971.
Rookery Building
The Rookery Building is a historic landmark, office building located at 209 South LaSalle Street in the Loop community area of Chicago in Cook County, Illinois, United States. Completed by John Wellborn Root and Daniel Burnham of Burnham and Root in 1888, it is considered one of their masterpiece buildings, and was once the location of their offices. The building is high, twelve stories tall, and is considered the oldest standing high-rise in Chicago. It has a unique style with exterior load-bearing walls and an interior steel frame, which provided a transition between accepted and new building techniques. The lobby was remodeled in 1905 by Frank Lloyd Wright. Beginning in 1989, the lobby was restored to the original Wright design.
