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.
Monadnock Building
The Monadnock belongs to the Printing House Row District, a National Historic Landmark which includes the Manhattan Building, the Old Colony Building, and the Fisher Building, some of Chicago's seminal early skyscrapers. The Manhattan Building, built by William LeBaron Jenney in 1890, was the first building in Chicago with a complete steel skeleton or "Chicago" construction, an innovation Jenney had introduced in the Home Insurance Building in 1884. The first 16-story building in America, at the time it was "regarded with awe and fear". Jenney's masterpiece, the Manhattan was considered a technical triumph in construction. The 17-story Old Colony, built by Holabird & Roche in 1894, was considered one of the structural masterpieces of its time for its revolutionary portal form of bracing. It is the only survivor of a group of Chicago school buildings with rounded corner bays. The Fisher Building, built by Burnham in 1894, was an engineering miracle—the first tall commercial building to be built almost entirely without bricks. Its steel frame and thin terracotta curtain wall allowed two-thirds of the surface to be covered with glass.
