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.
Prairie Avenue
Historic preservation in Chicago has saved some of the city's architectural heritage. The efforts of the Chicago Architecture Foundation and the Landmarks and Preservation Council of Illinois have been at the forefront of these efforts. The Commission on Chicago Landmarks (now part of the city's Department of Planning and Development) has designated the Prairie Avenue Historic District as a city landmark.
A few of the mansions of the heyday still remain in the 1800-block including the National Historic landmark designated John J. Glessner House designed in 1886 by architect Henry H. Richardson for Glessner; these provide a sense of the street's former character. Glessner House, which was the subject of a notable preservation battle in the 1960s, is considered to be Richardson's finest urban residence. This district includes the Henry B. Clarke House, which although twice relocated is purported to be the city's oldest standing house. In addition to the Clarke House and the Glessner House, nine other houses from the late-19th century remain in the historic district portion of Prairie Avenue. Both the Glessner House and the Clarke House are on the National Historic Register and now serve as museums. Most of the Prairie Avenue families worshiped at the Chicago Landmark Second Presbyterian Church of Chicago, which is listed on the National Register of Historic Places.
