Parks in Chicago include open spaces and facilities, developed and managed by the Chicago Park District. The City of Chicago devotes 8.5% of its total land acreage to parkland, which ranked it 13th among high-density population cities in the United States in 2012. Since the 1830s, the official motto of Chicago has been Urbs in horto, Latin for "City in a garden" for its commitment to parkland. In addition to serving residents, a number of these parks also double as tourist destinations, most notably Lincoln Park, Chicago's largest park, visited by over 20 million people each year, is one of the most visited parks in the United States. Notable architects, artists and landscape architects have contributed to the 570 parks, including Daniel Burnham, Frederick Law Olmsted, Jens Jensen, Dwight Perkins, Frank Gehry, and Lorado Taft. History In 1836, a year before Chicago was incorporated, the Board of Canal Commissioners held public auctions for the city's first lots. Foresighted citizens, who wanted the Lake Michigan lakefront kept as public open space, convinced the commissioners to designate two lots as public area. The land east of Michigan Avenue between Madison Street and Park Row (11th Street) was designated "Public Ground—A Common to Remain Forever Open, Clear and Free of Any Buildings, or Other Obstruction, whatever." This lot was soon expanded to Randolph Street, and it was officially named Lake Park in 1847. It was renamed Grant Park in 1901. A second parcel, west of Michigan Avenue between Randolph and Washington Streets, was designated Dearborn Park. As Chicago grew, demand increased for public spaces, but the Chicago Common Council did little to address these requests. Instead, real estate investors realized that small public squares could increase the value of their property. In 1842, Washington Square Park became the first of these ventures, developed by the American Land Company. Similar projects were completed with Goudy Square Park in 1847 and Union Park in 1853. Although the Cook County Court agreed to allocate a major park on the South Side in 1857, these plans were rescinded two years later, and public outcry continued. Chicago's second large-scale allocation of parkland came in 1860, when a large section of the City Cemetery was re-designated as a park. This was due to concerns led by John Henry Rauch about the possible public health impact of having a large cemetery on the lake. This new park was also named
