Golden Gate Park, located in San Francisco, California, United States, is a large urban park consisting of of public grounds. It is administered by the San Francisco Recreation & Parks Department, which began in 1871 to oversee the development of Golden Gate Park. Configured as a rectangle, it is similar in shape but 20 percent larger than Central Park in New York, to which it is often compared. It is over three miles (3mi) long east to west, and about half a mile (0.5mi) north to south. With 13 million visitors annually, Golden Gate is the fifth most-visited city park in the United States after Central Park in New York City, Lincoln Park in Chicago, and Balboa and Mission Bay Parks in San Diego.HistoryIn the 1860s, San Franciscans began to feel the need for a spacious public park similar to Central Park, which was then taking shape in New York City. Golden Gate Park was carved out of unpromising sand and shore dunes that were known as the Outside Lands, in an unincorporated area west of San Francisco’s then-current borders. Conceived ostensibly for recreation, the underlying purpose of the park was housing development and the westward expansion of the city. The tireless field engineer William Hammond Hall prepared a survey and topographic map of the park site in 1870 and became its commissioner in 1871. He was later named California's first state engineer and developed an integrated flood control system for the Sacramento Valley. The park drew its name from nearby Golden Gate Strait.
