Johannesburg is South Africa’s largest city and the economic heart of the country, located on the high plateau of the Highveld in Gauteng province. Founded in 1886 after the discovery of gold on the Witwatersrand reef, it grew within a few decades from a mining camp into one of Africa’s largest cities, and it remains the country’s principal financial and commercial center even though it has never been South Africa’s capital.

Where Is Johannesburg Located?

Johannesburg sits on the Witwatersrand, a rocky ridge on South Africa’s interior plateau at an elevation of roughly 1,750 meters, in Gauteng province. Unlike many major world cities, it was not built on a river, coastline, or natural harbor; it exists because of the gold-bearing rock beneath it.

A Brief History of Johannesburg

Johannesburg was founded in 1886 after prospectors confirmed a major gold reef on the Witwatersrand, meaning “ridge of white waters,” triggering a gold rush that drew migrants from across southern Africa and overseas. The settlement grew so quickly that it became known as an “instant city,” reaching tens of thousands of residents within a decade of its founding.

Apartheid and Its Legacy

Johannesburg became a focal point of South Africa’s twentieth-century segregation policies: the township of Soweto, on the city’s southwestern outskirts, was the site of the 1976 student uprising against apartheid-era education policy, and it was home to Nelson Mandela before his imprisonment. The city’s history of forced removals and segregated development under apartheid continues to shape its urban geography today.

Johannesburg Today: Economy and Culture

Johannesburg, often called “Joburg” or “Jozi” and known in Zulu and Sotho as eGoli, meaning “place of gold,” remains South Africa’s largest city and its financial capital, hosting the Johannesburg Stock Exchange, the largest stock exchange in Africa.^[1] It functions as the commercial hub for a wider metropolitan region that includes Pretoria, even though Pretoria, not Johannesburg, serves as South Africa’s administrative capital.

The Nelson Mandela Bridge

Johannesburg’s most recognizable modern landmark is the Nelson Mandela Bridge, a cable-stayed bridge opened in 2003 that links the Braamfontein district to Newtown across a wide expanse of railway lines. Named for South Africa’s first democratically elected president, the bridge has become one of the most frequently photographed symbols of the city’s post-apartheid skyline.

What Is Johannesburg Known For?

Johannesburg is known as South Africa’s economic engine and as a city shaped by the search for gold, from the historic mine dumps that still mark its skyline to museums such as the Apartheid Museum that document its more difficult history.

Why Johannesburg Matters

Johannesburg matters as the commercial and financial capital of South Africa and one of Africa’s most important economic centers, and as a city whose layout and institutions still bear the marks of the mineral discovery that created it and the segregation policies that shaped its growth.
