Wikipedia states, “Promontory Point (known locally as The Point) is a man-made peninsula jutting into Lake Michigan. It is located in Chicago’s Burnham Park. The Point was constructed from landfill and by the late 1930s was protected by a seawall or revetment. The revetment was designed and constructed by Chicago Park District engineers and consists of limestone blocks arranged in a series of four steps leading to a promenade.
Located on Chicago Park District land at 55th Street in Chicago’s south side Hyde Park neighborhood, it was opened to the public in 1937. Alfred Caldwell, a disciple of Jens Jensen, designed the landscaping, following the Prairie School which uses native plants and stone. Caldwell’s design featured a raised “meadow” section in the center of the 12-acre (49,000 m2) peninsula and included hundreds of flowering trees and shrubs. In 1938, Caldwell created stone sitting rings – called ‘council rings’ – around the lakefront edge, which today are used as fire pits. Few of Caldwell’s original plantings remain today.”
