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.[96] 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.[97] The first 16-story building in America, at the time it was "regarded with awe and fear".[98] Jenney's masterpiece, the Manhattan was considered a technical triumph in construction.[99] 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.[100] It is the only survivor of a group of Chicago school buildings with rounded corner bays.[101] The Fisher Building, built by Burnham in 1894, was an engineering miracleâ€”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.[102]
