It has kept its building stock largely intact, with no single style dominant. It also holds one of the largest concentrations of Walter Burley Griffin houses (12) and work by Frank Lloyd Wright and other Prairie School architects.","narrative":"Covering roughly 212 acres in Chicago's far southwest side, this district takes in most of the Beverly and Morgan Park neighborhoods along the Blue Island Ridge, the highest and hilliest ground in the city. Early residents included Potawatomi travelers on a trail later known as the Vincennes Road, followed by settlers in the 1830s and 1840s. Railroad service and the subdivisions of the Blue Island Land and Building Company drove residential growth from the late 1860s, and the area matured by about 1930. Houses date from the 1870s onward and span Italianate, Queen Anne, Romanesque, Tudor and Prairie School designs, including twelve by Walter Burley Griffin and one by Frank Lloyd Wright. Large lots, mature trees, an oak grove and the ridge's natural contours give the area a spacious, almost suburban character. Its listing rests on the unusual cohesion, diversity and quality of its architecture within a preserved landscape setting.","period_of_significance":null,"architect_builder":"Walter Burley Griffin, Frank Lloyd Wright, Dwight Perkins, Tallmadge & Watson, Spencer and Powers, Von Holst and Fyfe, Charles H.
