The town was platted in 1857 and the district covers roughly 1,019 acres.","why_significant":"The nomination argues the district is one of the most beautiful suburban towns in the United States, with large estates in park-like settings on a picturesque winding street plan laid out in 1857. It was the home of many prominent Chicago business figures. Its architecture reflects the conservative, traditional tastes of wealthy Chicagoans and includes work by many noted architects and landscape architects.","narrative":"Lake Forest Historic District takes in most of the original town of Lake Forest, Illinois, about 30 miles north of Chicago on the Lake Michigan shore. The town was laid out in 1857 by topographer Jed Hotchkiss, whose winding streets follow wooded bluffs and ravines and give the area a park-like character. Large country houses sit on lots ranging from one to fifty acres, alongside Lake Forest University, Barat College, Ferry Hall, and Market Square, described as an early planned shopping center designed for the automobile. Of 474 structures, 101 were judged especially significant, while recent construction accounts for about a third of the total. Tudor, Classical and Gothic styles dominate, and architects such as Howard van Doren Shaw, Charles Frost, Henry Ives Cobb and David Adler designed many buildings. Landscape architects including O.C. Simonds and Jens Jensen shaped its estates. Many leading Chicago business figures built homes here.","period_of_significance":null,"architect_builder":"Many architects, including Howard van Doren Shaw, Charles S.
