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.
West Loop–LaSalle Street Historic District
The West Loop–LaSalle Street Historic District is a historic district centered on LaSalle Street in the western Chicago Loop. The district encompasses Chicago's financial center, which is anchored by the Chicago Board of Trade Building, and also includes several of its major government buildings. Development in the district began in 1873 and, with the exception of a lull during the Great Depression and World War II, has continued through the present day. Most of the district's buildings are high-rises with at least ten stories, with the tallest being the 49-story One North LaSalle Building. Many of Chicago's prominent architectural firms designed buildings within the district, and the buildings feature styles such as Classical Revival, Chicago School, Art Deco, Romanesque Revival, and International. Significant buildings within the district include the Federal Reserve Bank of Chicago, Chicago City Hall, and several office buildings for large banks and insurance companies.
