Frederick Law Olmsted Sr. planned it from the late 1870s, with designs dated 1879, 1881, 1885 and 1892.","why_significant":"The nomination calls it one of the nation's outstanding examples of multi-use open space and Olmsted's finest design project in New England. It joined municipal open space with an engineering fix for sewage and flooding, linked newly annexed areas to the historic city centre, and offered varied recreation. Franklin Park is described as one of Olmsted's masterpieces, designed for working-class people.","narrative":"Boston's Olmsted Park System is a chain of parks and parkways, often called the Emerald Necklace, that curves south from the Back Bay Fens through the Muddy River corridor, Jamaica Pond and the Arborway to Franklin Park. Frederick Law Olmsted Sr. planned it in the late 1870s and after, partly to replace a polluted, flood-prone tidal swamp with an informal park. The plan also tied newly annexed parts of the city to its historic center and offered varied recreation, from pond boating to riding and picnicking. Franklin Park, designed in 1885 as a rural retreat for working-class residents, ended the system. Surviving features include bridges and a shelter by Shepley, Rutan and Coolidge, Richardson's Boylston Street bridge, and sculpture by Daniel Chester French. Overpasses, a stadium and other additions have altered parts, but much of Olmsted's road pattern remains. The system is recognized as a national example of large-scale landscape and regional planning.","period_of_significance":"19th and 20th Century; specific dates 1879, 1881, 1885, 1892","architect_builder":"Frederick Law Olmsted Sr. (landscape design); Shepley, Rutan and Coolidge (bridges and shelter); City Architect Wheelwright; Walker and Best (Valley Gate); Daniel Chester French (sculpture)","architectural_style":null,"criteria":[],"status_note":"Publicly owned and in use as parks.
