The city of Antofagasta is closely linked to mining activity, being a port and the chief service hub for one of Chile's major mining areas. While silver and saltpeter mining have been historically important for Antofagasta, since the mid-19th century copper mining is by far the most important mining activity for Antofagasta, fueling a steady growth in the areas of construction, retail, hotel accommodations, population growth and skyline development until the end of the 2000s commodities boom in 2013. Since the 2010s Antofagasta is also a service hub for lithium mining.
Antofagasta is the seat of one of Chile's three environmental courts and is also a university city being the home of the Catholic University of the North and the University of Antofagasta.
In 2012, Antofagasta has the highest GDP per capita of Chile, US$37,000 and the 3rd place for Human Development Index just after Metropolitana de Santiago Region and Magallanes and Antártica Chilena Region.
History
Early settlers
The territory of Antofagasta was included in maps of the Captaincy General of Chile in the 18th century, depending from the city of Copiapó.The territory was disputed between Chile and Bolivia until the signing of the Boundary Treaty of 1866.
On 18 September 1866, José Santos Ossa and Francisco Puelma achieved the award of the concession of nitrate lands, following a request taken to the Bolivian government. The exploring of the Chilean miners found rich deposits of saltpeter in the field of Salar del Carmen, to the east of the present Antofagasta. Agreed to form the "Sociedad Exploradora del Desierto de Atacama". After the formation of the company, began to fill with what was called "La Chimba".
On 8 May 1872, Antofagasta was designated by the Bolivian Government as Puerto Mayor, opening trade worldwide.
On 27 November 1873, the "Compañía de Salitres y Ferrocarril de Antofagasta", a Chilean mining company, signed a contract with the government of Bolivia, in which taxes were removed from mineral exploitation for 15 years. This contract was not ratified by the Congress of Bolivia, which was then analyzed negotiations with Chile.
War of the Pacific
In 1873, Bolivia signed a secret treaty of defensive alliance with Peru. This would be used as an argument 5 years later in Chile, when it unleashed the War of the Pacific. The secret alliance forbade Bolivia from signing a border treaty with Chile, without consulting with Peru. However, in 1874 Chile and Bolivia signed a border treaty, which replaced the previous treaty of 1866. One of its points was not to impose new taxes on individuals, industries and Chilean capital for 25 years.For Bolivia, the contract of 1873 between the government and CSFA was not yet in force, because, according to the Bolivian constitution, all contracts with the Bolivian government had to be approved by the congress.
According to the Bolivian version of events, the contract with the saltpeter company was incomplete so the congress, to approve the contract, decided to enforce a tax of 10 cents, which did not violate the treaty of 1874, since the contract was not yet in force at that date. Bolivia suspended the tax in deference to the government of Chile, but following a note from the Chilean foreign minister, it reactivated the tax law, then cancelled and closed the "Compañía de Salitres". Faced with a looming conflict with Chile, Bolivia decided to claim support under the agreement signed with Peru, and the treaty became effective with the Chilean occupation of Antofagasta, on 14 February 1879.
20th century
The Treaty of Peace and Friendship between Chile and Bolivia, signed on 20 October 1904, and promulgated on 21 March 1905, established in perpetuity border between Chile and Bolivia.In 1912, the British community erected a clock tower, replicating Big Ben, in Plaza Colón to celebrate the republic's centenary.
In 1956, the Universidad del Norte was founded, due to support from the Catholic University of Valparaíso. On 9 October, of the same year began the negotiations for the creation of the "Centro Universitario Zona Norte", part of the University of Chile.
On 18 June 1991, a mudslide devastated much of the city, undermining land, damaged 2,464 houses and destroyed 493 buildings. Material damage was estimated at $70,000,000. The disaster left 92 dead, 16 missing and about 20,000 homeless. On 30 July 1995, the city was hit by an earthquake measuring 7.3 on the Richter Scale, with an intensity VII to VIII on the Mercalli Scale.

The Tropic of Capricorn passes in the north of the city, outside the urban area, which is located the Cerro Moreno International Airport. The Tropic of Capricorn Monument was opened on 21 December 2000 in celebration of this.

Antofagasta was declared a partial common in the border area 20 July 1999, by Supreme Decree No. 1166 of the Ministry of Foreign Affairs.
The city has little vegetation because it is situated in the Atacama Desert, which is the world's driest nonpolar desert. However, among the vegetated areas are a series of urban wetlands. Native reptiles, arthropods, birds like the Calidris and mammals like the culpeo fox, inhabit or visit the wetlands. Some of these wetlands are threatened by garbage, street dogs, extraction of water, establishments of shacks and the diversion of water courses. As of January 2024 the municipality of Antofagasta plans to declare the wetlands official urban wetlands in accordance with the Urban Wetlands Law.

Just north of the city, natural beaches extend to the areas of "La Portada", "Las Losetas" and "La Rinconada".
