Chapultepec, more commonly called the "Bosque de Chapultepec" (Chapultepec Forest) in Mexico City, one of the largest city parks in the Western Hemisphere, measuring in total just over 686 hectares (1,695 acres). Centered on a rock formation called Chapultepec Hill, one of the park's main functions is to be an ecological space in the vast megalopolis. It is considered the first and most important of Mexico City's "lungs", with trees that replenish oxygen to the Valley of Mexico. The park area has been inhabited and held as special since the Pre-Columbian era, when it became a retreat for Aztec rulers. In the colonial period, Chapultepec Castle would be built here, eventually becoming the official residence of Mexican heads of state. It would remain such until 1940, when it was moved to another part of the park called Los Pinos. Today, the park is divided into three sections, with the first section being the oldest and most visited. This section contains most of the park's attractions including its zoo, the Museum of Anthropology, the Rufino Tamayo Museum, and more. It receives an estimated 15 million visitors per year. This prompted the need for major rehabilitation efforts which began in 2005 and ended in 2010.
Chapultepec Park is the largest city park in Latin America, measuring in total just over 686 hectares. It is classed as one of the world's great urban parks, along with Bois de Boulogne in Paris, the Imperial Gardens in Tokyo and Central Park in New York City. The name "Chapultepec" means "at the grasshopper hill" in Nahuatl and refers to a large rock formation that is the center of the current park's "first section". Originally, this area was a forest outside of Tenochtitlan/Mexico City considered sacred in pre-Columbian times, but today it is entirely within the city (mostly in the borough of Miguel Hidalgo), surrounded by some of its primary business and commercial districts. The park is divided into three sections, the first and oldest surrounded by fence and shut at night, and the other two left open. It contains nine museums, amusement parks, winding paths, commemorative sculptures, lakes and fountains.Paseo de la Reforma passes most of the park and cuts through a portion on the north side.
