Johannesburg was born on October 4, 1886 when Johann Rissik traced the first streets on Randjeslaagte farm, six months after George Harrison's discovery. Main Street immediately became the main artery of the mining camp, 2 km long, where the first prospectors from Australia, California and the Klondike flocked. From 1887, iron buildings imported from England replaced tents to resist fires that regularly ravaged the camp. You walk on cobblestones laid by these first gold seekers who unknowingly trod the world's richest gold deposit.
The Old Post Office, built in 1897-1898 in Dutch Victorian style, became the first permanent government building of this mushroom city. Its 45-meter clock tower, visible from 5 km away, guided prospectors to the administrative center where they registered their mining claims from 1897. One hundred postal employees processed correspondence for 100,000 inhabitants in less than ten years. Gandhi Square, formerly Government Square, saw Mahatma Gandhi launch his first civil disobedience campaign in 1906 against discriminatory laws on Asian registration, numerous among traders supplying the mines.
The Rand Club, founded in 1886 by British prospectors, became the unofficial headquarters of the nascent gold industry. In its 1902-1903 Edwardian building, Cecil Rhodes and the Joel brothers negotiated mining rights in 1887 that would shape South Africa's economy. Its library preserves 10,000 volumes on gold history, including personal diaries of the first prospectors. The Standard Bank Centre displays in its 500 m² underground space native gold samples extracted from the Witwatersrand since 1886, testament to the institution that managed 70% of gold transactions in 1890.
The Market Theatre Precinct rises on the former Indian Fruit & Vegetable Market of 1913, where migrant mine workers came to shop. Mary Fitzgerald Square bears the name of the Irish trade unionist who organized the 1913-1914 mining strike, the first major workers' revolt against exploitation conditions. Her 1989 statue overlooks the 8,000 m² where miners gathered during 1922 demonstrations, when 20,000 white workers revolted against hiring cheaper black labor.
Your journey through Johannesburg's historic CBD reveals how a chance discovery in July 1886 created southern Africa's largest city. Each Victorian facade, each commemorative plaque tells the epic of these 120,000 adventurers who extracted over 40,000 tons of gold from the Witwatersrand. You leave with visceral understanding of this rush that forged modern South Africa, its inequalities and riches, etched in every stone of this metropolis born from gold fever.
