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.
Former Chicago Historical Society Building
The Former Chicago Historical Society Building is a historic landmark located at 632 N. Dearborn Street on the northwest corner of Dearborn and Ontario streets near downtown Chicago. Built in 1892, the granite-clad building is a prime example of Henry Ives Cobb's Richardsonian Romanesque architecture. The building was designated a Chicago Landmark in 1997. It was listed on the National Register of Historic Places in 1978, under the name, Old Chicago Historical Society Building.
