The Ridge Historic District, which runs from 87th Street to 115th Street and sometimes reaches as far west as Western Avenue and as far east as Prospect Avenue in Chicago's Beverly neighborhood, is one of the largest urban districts on the National Register of Historic Places. So pack your most comfortable walking shoes or take a drive along scenic Longwood Drive from 119th Street to 95th Street. a trip I used to take frequently as a teenager. The district features more than 3,000 remarkable homes designed by some of history's great architects, including Frank Lloyd Wright, George W. Maher, Walter Burley Griffin, Daniel Burnham and Howard Van Doren Shaw. Five landmark residences not to miss include the Iglehart House, an Italianate farmhouse and one of the city's oldest surviving buildings; the William and Jessie Adams House, which was designed by Frank Lloyd Wright in his Prairie school style; the two American System-Built homes designed by Frank Lloyd Wright as affordable prefab dwellings; and Palliser's Cottage Home #35, one of the best preserved examples of pattern book architecture that was sold through the mail in the Midwest. Visit the Beverly/Morgan Park Railroad Station District where you'll find five structures built between 1889 and 1945, all representing rare examples of the late 19th and early 20th century commuter railroad stations in Chicago. Designed for the Chicago, Rock Island & Pacific Railroad, these Colonial Revival, Queen Anne and Richardsonian Romanesque-style stations are a unique glimpse into Chicago's rich railroad history.
