Wedged between East 89th Street, South Muskegon Avenue and the sycamore tree-lined South Chicago Avenue is the historic triangular Bessemer Park, named after English inventor Henry Bessemer, whose iron ore refining process revolutionized steel production. The park was designed by the Olmsted Brothers of the renowned landscape architect Frederick Law Olmsted of New York City's Central Park, as well as Chicago landmarks Washington Park and Jackson Park, built for the World's Columbian Exposition of 1891. Their work on the park started in early 1904 and finished late in 1905. The fieldhouse, only modestly upgraded, retains much of its original charm. The Bessemer Park Nature and Wildlife Garden is among Chicago's 23 noted natural "preserves" of native fauna and wildlife habitat. Bessemer Park and Russell Square Park on the corner of Bond Avenue and East 83rd Street (*the Bush), are among their last commissions, Bessemer Park is one of the largest parks on the South Side. Eckersall Playground Park and Stadium is centrally located in South Chicago at the corner of East 83rd Street and South Yates Avenue. Other new greenspaces are planned throughout the community including what is currently called "Park No. 503" at 8900 South Green Bay Avenue in the Millgate community. Designated bicycle paths from East 83rd Street, South Shore Drive/Mackinaw Avenue and South Chicago Avenue connect directly to the Burnham Greenway Trail which links to a comprehensive system of greenways throughout the Calumet Region.
