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.
Madison Street (Chicago)
Madison Street is a major east–west street in Chicago, Illinois. Prior to human intervention, the Chicago River emptied into Lake Michigan at the present day intersection of Madison Street and Michigan Avenue.
Per a 1908 decision by Chicago's city council, Madison serves as the north–south dividing line for Chicago's street numbering system, while State Street serves as the east–west line. At one point, the intersection between the two streets was considered the "world's busiest corner."
Notable buildings located along Madison Street include the Carson, Pirie, Scott and Company Building, Chase Tower, Three First National Plaza, the Chicago Civic Opera House, Citigroup Center and the United Center.
