Promontory Point (Chicago) facts for kids
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.
The site was designated as a Chicago Landmark on April 19, 2023.
Background
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.
The park is accessed by the Lakefront Trail, and a tunnel which passes under Lake Shore Drive at the east end of 55th Street. At the head of the park, seen immediately upon emerging from the 55th Street tunnel, is the David Wallach Memorial Fountain. This fountain was designed in 1939 by Elizabeth and Frederick Hibbard in the shape of a fawn, with drinking areas at human and animal levels. During the Cold War the park also housed a 150-foot (46 m) radar tower for the Nike Hercules missile defense system; it was dismantled in 1971.
The park contains a field house, built in 1937, the exterior of which is made of Lannon stone from Wisconsin. Partly because of its view of the lake and cityscape, it is a popular wedding and corporate event location. It competes with the much larger Jackson Park 63rd Street Beach House and the even larger South Shore Cultural Center as south side beachfront special use facilities. The frequent summer fireworks displays at Navy Pier are often viewed from The Point, especially on Independence Day, when large numbers of Hyde Parkers and other south side residents gather there. It neighbors the Museum of Science and Industry and the 57th Street Beach.
Water access is an important aspect of the Point's history of use. Swimmers, sunbathers, kayakers, and windsurfers use the Point's revetment to access the waters of Lake Michigan. People have been swimming off of the limestone revetment at Promontory Point since it was built, in 1937. In the summer months, the North side of the Point functions as a "rock beach." The water is shallow and the lake bottom is sand, making the North side a family friendly swimming area. On both sides of the Point, open water swimmers enter the water off the rocks and swim across the bays. Both North and South side swimming areas are marked with "Swimming Area" buoys in the summer months. In the past, open water, or distance, swimming was a source of conflict with the Chicago Park District as the legality of swimming off the Point is ambiguous. From time to time, swimmers were ticketed. Recently, however, the Chicago Park District created an officially sanctioned open water swimming area off the South side of the Point. All motorized boat traffic is prohibited inside the buoyed areas.
Events
Though open-water swimming continues year-round for the brave and hearty, there are spring and fall swimming events, held on weekends near the summer solstice and the autumnal equinox to celebrate the tradition and community of swimmers at the Point.
The Spring Swim Around the Rocks is held each year on the Sunday following the summer solstice. The Fall Swim Around the Rocks is held each year on the Sunday preceding the autumnal equinox. These events are open and no registration is required. Spectators watch from the shore while swimmers enter the water at the South side ladders and swim around to the north side shallows, completely circumnavigating the Point. The route then reverses back to the ladders (some swimmers complete a half-course).
Revetment
Much of Chicago's lakefront was landfill. To protect this lakefront park land, a seawall or revetment was built by the Chicago Park District in the 1930s. This revetment consists of limestone blocks (with an average weight 2 to 4 tons) arranged in a series of “steps” leading down to the lake. These blocks are supported by a crib structure made from wooden timbers that encloses crushed rock. At the outer edge of the revetment, a series of wooden pilings, held together by a steel rail, keep the limestone blocks from tumbling into the lake.
At the Point, the revetment features four steps leading down to a 16-foot (4.9 m) wide promenade. The revetment at the Point is exposed to severe wave action and had partially failed by the early 1960s. A 1,000-foot (300 m) section of the revetment (out of approximately a 6,000-foot (1,800 m) total length) at the Northeast tip of the Point was repaired by removing the limestone blocks that form the promenade and pouring a pad of 3 feet (0.91 m) of concrete over the badly eroded crib structure. This repair stands today.
By the 1980s, the City and the CPD began a project to repair the revetment along almost all of the city's lakefront. Federal funds were sought from the U.S. Army Corps of Engineers, and a project study was begun. The conclusion of the study, published in the 1993, was that different areas of the revetment needed different treatments. At Promontory Point, a historic preservation treatment was agreed to and signed into public contract, and into law when the Congress approved the project, in a memorandum of agreement. This document states that “the Corps shall consult with the SHPO (state historic preservation officer), the City of Chicago and the Chicago Park District to ensure that the design and construction of the revetment will match the existing in accordance with the recommendations of the Secretary of the Interior's ‘Standards and Guidelines for Archeology and Historic Preservation’."
As the project moved forward and was finally funded, the ACOE, the City and the CPD changed the design at Promontory Point. The new plan called for the demolition of the historic revetment, and replacement by a monolithic concrete seawall.
In January 2001, the City and CPD held a community meeting to announce their plans for the Point revetment. This started a controversy that has not yet been resolved.
