Johannesburg holds 5.6 million people in its metropolitan area according to the 2022 census, making it substantially larger than Cape Town's 4.7 million. The city sits at 1753 meters elevation on the interior Highveld plateau, 1400 kilometers northeast of Cape Town. Gold was discovered on the Witwatersrand reef system in 1886, and the mining camp that formed around George Harrison's find on the farm Langlaagte became a city within a decade. By 1895 Johannesburg's population exceeded 100,000, more than three-quarters arriving within those nine years. The reef extends 56 kilometers east to west and has yielded approximately 40 percent of all gold ever mined in human history. The city remains South Africa's economic center, generating 16 percent of the country's gross domestic product and hosting the Johannesburg Stock Exchange, which trades R15 trillion in equity annually.
The central business district developed around Commissioner Street and the original mine works. Mine dumps, the residue from gold extraction, once dominated the skyline as yellow geometric hills reaching 60 meters high. Beginning in 2006, these dumps underwent reprocessing as newer extraction techniques made previously discarded material economically viable. Crown Mines dump, covering 270 hectares southwest of the city center, was completely removed by 2014. The Hillbrow Tower, completed in 1971, rises 269 meters and served as the primary telecommunications structure for Gauteng province. The tower carried 90 percent of Johannesburg's telecommunications traffic until fiber optic networks reduced its role after 2000. Ponte City, the cylindrical residential tower in Hillbrow completed in 1975, stands 173 meters with 54 floors. The building declined through the 1990s, experienced occupancy rates below 40 percent by 1998, and underwent renovation beginning in 2007.
Soweto, the acronym for South Western Townships, developed as the primary residential area for Black workers during segregation. The township covers 200 square kilometers southwest of the city center and housed 1.27 million people in the 2011 census. The Natives Resettlement Act of 1954 forced approximately 60,000 people from areas designated for whites into Soweto. Orlando Power Station operated from 1935 to 1998, providing electricity for the goldfields. The facility now functions as an entertainment venue, with two cooling towers converted into vertical adventure sports platforms in 2008. Vilakazi Street in Orlando West is the only street in the world where two Nobel Peace Prize laureates have lived. Nelson Mandela resided at number 8115 from 1946 until his arrest in 1962. Archbishop Desmond Tutu has lived at number 7546 since purchasing the property. The street became a national heritage site in 2004.
The Hector Pieterson Memorial and Museum in Orlando West marks the events of June 16, 1976, when police fired on students protesting the mandatory use of Afrikaans in schools. Hector Pieterson, age 12, was among the first killed. The photograph by Sam Nzima showing Mbuyisa Makhubo carrying the dying Pieterson reached international audiences within 48 hours. Official accounts initially listed 23 deaths, but the South African Institute of Race Relations documented 176 fatalities in the weeks that followed. The museum opened on June 16, 2002, on the original protest route. The memorial includes the Nzima photograph rendered as a two-meter concrete monument.
Constitutional Hill occupies the site of the Old Fort prison complex, which operated from 1892 to 1983. The prison held both common criminals and political detainees. Mahatma Gandhi served time there in 1906 and 1908 for his passive resistance campaigns. Nelson Mandela, Albertina Sisulu, and Winnie Madikizela-Mandela were incarcerated in separate sections during apartheid. The Constitutional Court, South Africa's highest judicial authority, began hearing cases on the site in 2004. The court building incorporates bricks and structural elements from the demolished prison sections. The court hears 80 to 100 cases annually and employs 11 justices who serve non-renewable 12-year terms. Chief Justice Pius Langa presided at the building's opening. The Number Four section, where awaiting-trial prisoners were held, remains preserved as it existed in 1983.
The Apartheid Museum opened in 2001 on Gold Reef Road, adjacent to the Gold Reef City casino complex. Entry tickets randomly designate visitors as white or non-white, directing them through separate entrances that replicate apartheid-era segregation. The museum contains 22 individual exhibition areas covering 7000 square meters. Permanent displays include the 131 nooses representing political executions at Pretoria Central Prison, photographs documenting the Sharpeville massacre of March 21, 1960, and the original Immorality Act signage that prohibited relationships across racial classifications. More than 4 million people visited between 2001 and 2021. The museum receives no government funding, operating on admission fees of R130 for adults and R90 for children as of 2023.
The Cradle of Humankind World Heritage Site covers 47,000 hectares northwest of Johannesburg, encompassing 13 separate fossil excavation sites. The Sterkfontein Caves have yielded more than 500 hominid fossils, including Mrs. Ples, an Australopithecus africanus skull dated to 2.05 million years ago and discovered by Robert Broom in 1947. Little Foot, a nearly complete Australopithecus skeleton found by Ronald Clarke in 1994 and fully excavated by 2012, dates to approximately 3.67 million years ago. The Rising Star Cave system, discovered in 2013, contained more than 1,550 specimens of Homo naledi, a previously unknown hominin species announced in 2015. Lee Berger led the excavation using six scientists small enough to navigate the 18-centimeter-wide passage to the Dinaledi Chamber where the fossils lay. The Maropeng Visitor Centre, which opened in 2005, receives approximately 250,000 visitors annually.
Johannesburg's climate produces 713 millimeters of rainfall annually, with 80 percent falling between October and March. The city lies in the summer rainfall zone, distinct from Cape Town's winter rainfall pattern. January temperatures average 26 degrees Celsius during the day and drop to 15 degrees at night. July temperatures range from 16 degrees during the day to 4 degrees at night. Frost occurs on average 12 nights per year, typically in June and July. Afternoon thunderstorms develop rapidly during summer months, with lightning density among the highest globally at approximately 12 strikes per square kilometer annually. The highveld location produces intense ultraviolet radiation, with UV index commonly reaching 11 during December and January.
The city contains no natural perennial water sources, depending entirely on reservoir systems. The Vaal River system, located 60 kilometers south, supplies approximately 60 percent of Johannesburg's water through the Vaal Dam, completed in 1938 with a capacity of 2.6 billion cubic meters. Rand Water, established in 1903, operates the treatment and distribution infrastructure serving 11 million people across Gauteng. The organization pumps water 300 meters uphill from the Vaal River to Johannesburg using 1600 megawatts of electricity annually. Water loss through leaking infrastructure reached 37 percent of treated water in 2020, according to Rand Water's annual report. The City of Johannesburg implemented stage 1 water restrictions in September 2023, limiting garden irrigation to specific days.
Johannesburg lacks passenger rail connections to other major cities. Shosholoza Meyl operates one passenger service weekly to Cape Town and one to Durban, both departing from Park Station. The Cape Town journey covers 1532 kilometers in approximately 26 hours, departing Friday afternoons and arriving Saturday evenings. The Durban route spans 712 kilometers in 14 hours, departing Sunday evenings. The Gautrain rapid rail system, opened in 2010 ahead of the FIFA World Cup, connects Johannesburg's Sandton district with OR Tambo International Airport and Pretoria. The 80-kilometer network carries approximately 50,000 passengers daily across 10 stations. Single journey fares range from R16 to R92 depending on distance.
OR Tambo International Airport, located 21 kilometers east of the city center, handled 21.3 million passengers in 2019, before the pandemic reduced traffic to 8.5 million in 2020. The airport serves as the primary hub for South African Airways and hosts 70 international airlines. Direct flights connect Johannesburg to 45 African cities, 15 European destinations, and eight locations in the Middle East and Asia. The airport operates two parallel runways, each 4,418 meters long, and the elevation of 1,694 meters requires longer takeoff distances than sea-level airports. Terminal renovations completed in 2010 increased capacity from 18 million to 28 million passengers annually. The Gautrain station within the airport connects to Sandton in 15 minutes with trains departing every 12 minutes during peak hours.
Minibus taxis transport approximately 60 percent of Johannesburg's commuters, operating on 1,250 routes across the metropolitan area. The industry involves 15,000 vehicles and employs 100,000 people, according to the South African National Taxi Council. Vehicles seat 15 passengers but commonly carry 20 during peak hours. Fares range from R8 for short trips to R25 for journeys across the city. The Rea Vaya bus rapid transit system, launched in 2009, operates on dedicated lanes along major corridors. The system covers 320 kilometers of routes serving 330,000 passengers daily. The fare structure uses a smartcard system with trips costing between R8.50 and R17.
The Johannesburg Art Gallery, opened in 1915, holds the largest art collection in Africa with 9,000 works. Lady Florence Phillips, wife of mining magnate Lionel Phillips, donated her personal collection and funded the building's construction. The collection includes 17th-century Dutch paintings, British works from the 18th and 19th centuries, and significant holdings of South African art from 1900 onward. Works by Gerard Sekoto, Maggie Laubser, and Irma Stern occupy dedicated galleries. The museum closed temporarily in 2018 due to structural issues and reopened sections in 2021 after R32 million in repairs. Security concerns led to the relocation of high-value works to climate-controlled storage in 2012, with approximately 3,000 pieces remaining on public display.
Market Theatre, opened in 1976 in a converted produce market on Bree Street, operated as a non-racial venue during apartheid when such spaces were legally prohibited. Barney Simon served as artistic director from 1976 to 1995, staging works by Athol Fugard, Mbongeni Ngema, and Percy Mtwa. Woza Albert, created by Mtwa, Ngema, and Simon in 1981, played 2,000 performances internationally over eight years. The theatre complex includes three performance spaces: the main theatre seating 387, the Barney Simon Theatre with 180 seats, and the Laager with 90 seats. The Market Theatre Laboratory, established in 1989, provides tuition-free training for 60 students annually in a three-year program.
The University of the Witwatersrand, established in 1922, enrolls 40,000 students across five campuses. The institution originated as the South African School of Mines in 1896 in Kimberley, relocated to Johannesburg in 1904, and gained university status in 1922. The university awarded 26 percent of all doctorates granted by South African universities in 2021. Four faculty members have received Nobel Prizes: Aaron Klug for Chemistry in 1982, Nadine Gordimer for Literature in 1991, Nelson Mandela for Peace in 1993, and Sydney Brenner for Physiology or Medicine in 2002. The Origins Centre museum on campus houses fossils from the Cradle of Humankind sites and San rock art collections. The university's 2023 budget totaled R7.8 billion, with 36 percent derived from government grants.
Gold Reef City, opened in 1986 on the site of Crown Mines, recreates Johannesburg's 1880s mining town. The Crown Mines shaft, sunk in 1887, reached a depth of 3,167 meters by its closure in 1973. Visitors descend 220 meters into the restored shaft to view mining methods used between 1886 and 1971. The site includes 14 theme park rides added between 1986 and 2009. The Victorian-era buildings were sourced from Johannesburg's demolished structures, including the Standard Bank building from Commissioner Street and the original fire station from Jeppe Street. The on-site foundry pours gold at 1,064 degrees Celsius in daily demonstrations. Admission costs R270 for adults and R210 for children under 12 as of 2023.
Johannesburg's northern suburbs developed primarily after 1945 as formerly agricultural land converted to residential use. Sandton, incorporated as a separate municipality in 1969 and merged with Johannesburg in 2000, functions as the business district for multinational corporations. The Sandton Central Business District contains 280,000 square meters of office space and hosts the regional headquarters for 70 international companies. The Johannesburg Securities Exchange relocated from the original city center to Sandton in 2000. The area's expansion accelerated after 1991 when companies began moving operations from the city center, citing security concerns.
Alexandra, the township bordering Sandton, covers 800 hectares and housed 179,000 people in the 2011 census, producing a population density of 22,375 people per square kilometer. The township originated in 1912 on freehold land owned by Herbert Papenfus, making it one of the few areas where Black South Africans could own property during apartheid. The Jukskei River forms the northern boundary, flooding sections during heavy rains. Major flooding in 2010 displaced 800 families when the river exceeded its banks by 15 meters. The Alexandra Renewal Project, launched in 2001 with a budget of R1.3 billion, constructed 6,500 housing units and upgraded 12,000 informal structures by 2010.
The Maboneng Precinct, developed beginning in 2009 in the city center's eastern section, converted 45 abandoned industrial buildings into mixed-use spaces. Jonathan Liebmann purchased the first property for R300,000 in 2008 and established Propertuity, the development company. The area covers 12 city blocks bounded by Fox, Albrecht, Kruger, and Main Streets. Arts on Main, the primary commercial building completed in 2009, contains 150 artist studios, 22 retail outlets, and the Bioscope independent cinema with 42 seats. The Market on Main operates Sunday mornings, hosting 80 vendors selling prepared foods and crafts. Rental rates for one-bedroom apartments ranged from R6,500 to R12,000 monthly as of 2023.
Johannesburg generates 4,200 tons of solid waste daily, with 63 percent originating from residential sources and 37 percent from commercial and industrial activities. The Engen Landfill site in Robinson Deep received waste from 1980 to 2008 and covered 120 hectares at closure. The Marie Louise site in Linbro Park currently receives 2,500 tons daily and reached 78 percent capacity by 2022. The city operates four materials recovery facilities that process 900 tons of recyclable waste daily, recovering 21 percent of the total waste stream. The Pikitup organization, established in 2000, employs 5,800 workers and operates 450 refuse trucks serving 1.8 million properties.
The Lion Park, established in 1966 on a 500-hectare property north of Johannesburg, maintains 85 lions in semi-captive conditions. The facility breeds lions for trophy hunting and for sale to other parks and private collections, though it suspended cub petting experiences in 2019 following international criticism. The facility disclosed in annual reports that 108 lions were sold to hunting operations between 2008 and 2015. Entry fees generate R45 million annually according to the 2018 financial statement. The park added Nguni cattle, Ankole cattle, and Nile crocodiles to diversify attractions in 2010.
Orlando Stadium, constructed in 1959, seats 40,000 and served as a training venue during the 2010 FIFA World Cup. The stadium hosted the opening match of the 2013 Africa Cup of Nations between South Africa and Cape Verde on January 19, drawing 38,074 spectators. Orlando Pirates Football Club plays home matches at the venue, which underwent a R178 million renovation between 2008 and 2009. The renovation added 10,000 seats, replaced the natural grass with synthetic turf in 2018, and installed LED lighting. The club, founded in 1937, has won the Premier Soccer League five times since the competition began in 1996.
