Inscription. Possessing one of Chicago's most historically and ecologically significant landscapes, Jackson Park is currently undergoing exciting major improvements. In 1871, Frederick Law Olmsted (1822-1903), renowned designer of New York's Central Park, originally planned Jackson Park in conjunction with Washington Park and the Midway Plaisance. Olmsted prepared a second plan transforming Jackson Park into the 1893 World's Columbian Exposition. Two years later, Olmsted's firm created their final Jackson Park plan returning the fairgrounds to parkland. Today, remnants of the fair include the Museum of Science and Industry (original Fine Arts Palace) and Wooded Island (historic site of the Japanese Pavilion, known as the Ho-oh-den or Phoenix Pavilion). Though the pavilion burned down in 1946, the adjacent Garden of the Phoenix survives. In 2016, internationally acclaimed artist, musician, and peace activist Yoko Ono installed Sky Landing on the site of the historic Ho-oh-den. A symbol of peace, this lotus flower sculpture is her first permanent public artwork in America.

Jackson Park is an important space for recreation and contemplation,

as well as a vital natural resource. Each year, hundreds of species of birds rest and refuel here during their fall and spring migrations. The park's diverse plant life also provides habitat for a myriad of animals that live here year-round. To improve the ecological health of Jackson Park, promote its wildlife habitat, and rehabilitate its historic landscape, the Chicago Park District, U.S. Army Corps of Engineers, and Project 120 Chicago are working together on an ambitious capital project. Funded in-part through the Great Lakes Fishery and Ecosystem Restoration Program (GLFER), this five-year project fulfills ecological restoration and historic preservation goals, while enhancing the park user experience. Progress on this project is ongoing. with completion expected in the fall of 2019. You will find a location map on the reverse side of this sign.

Regarding Jackson Park Improvements. While not really explained on the sign, it is almost certain that the improvements being referenced are those sponsored in the mid-2010s by a private nonprofit called Project 120. The group sought to restore the landscape design to be closer to the vision of its original designer, Frederick Law Olmsted. It is possible that at least some, if not most, of these changes

predate those that came when Jackson Park was selected in 2016 as the site of the Barack Obama Presidential Center. The center opened about four-tenths of a mile north of here in the summer of 2026, after about eight years of construction, including numerous updates to the parkland nearby.
