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.
Old Main (Eastern Illinois University)
The Old Main, also known as the Livingston C. Lord Administration Building, is the oldest building at Eastern Illinois University in Charleston, Illinois. Construction on the building began in 1896 and was completed in 1899. Architect George H. Miller designed the building, which has a medieval style resembling a castle. The building features a central tower, multiple turrets, and a crenellated roof line. It is one of five medieval buildings built at Illinois' public universities under Illinois Governor John Peter Altgeld's administrations; the buildings are collectively known as Altgeld's castles. The Old Main originally housed all of the offices and classrooms for Eastern Illinois, its library, auditorium, and gymnasium; it was the only building on campus until 1909, when Pemberton Hall opened. The building is now used mainly as an administrative building, though it still contains some classrooms.
