Diagonal Street: Johannesburg’s Diamond of Diversity, History, and Urban Culture
Discover Diagonal Street—a crossroads of cultures, stunning architecture, and Johannesburg’s evolving cityscape from gold rush origins to modern urban life.
Introduction: The Heartbeat of Urban Johannesburg
Located in Johannesburg’s dynamic inner city, Diagonal Street stands as both a crossroads of South African history and a symbol of the city’s multicultural vibrancy. With architecture ranging from Victorian filigree to dazzling skyscrapers, this street weaves together stories of the gold rush, pioneering entrepreneurs, racial segregation, city planning innovation, and the resilience of diverse communities. Visitors to Diagonal Street experience not just a location, but a living tapestry of Johannesburg’s evolution—from mining frontier to metropolitan powerhouse.
Origins of Diagonal Street: From Jubilee to Gold Rush
Originally named Jubilee Street, Diagonal Street traces its roots to the late 19th century, emerging during the initial Johannesburg gold rush. Unlike its neighboring blocks, Diagonal Street famously defied the city’s rigid east-west and north-south grid, slicing diagonally through the central business district—a symbolic departure from convention and a visual echo of the city’s restless energy.
By 1897, its present name was adopted, commemorating the street’s distinctive geometry and position in the city’s burgeoning commercial landscape.
- Gold Rush Influence: The area was at the core of the city’s foundational gold rush activity, drawing entrepreneurs, traders, and settlers.
- Diverse Settlers: Diagonal Street quickly became a hub for Indian, Chinese, Colored, and other non-white traders, especially as racial zoning pushed communities into specific areas elsewhere.
- Exemption from Racial Segregation: The street initially operated outside harsh segregation laws, creating a busy, integrated commercial sector. Shops thrived with white proxy owners fronting for non-white traders, an arrangement that allowed the area’s market to flourish despite discriminatory regulations.
Architectural Eclecticism: Styles Old and New
Diagonal Street is celebrated for its eclectic architecture, a vivid tapestry interlacing historical structures and avant-garde modernity. Victorian facades brimming with filigree ironwork sit alongside bold office towers, making the street irresistible for photographers and architectural enthusiasts.
- Victorian Streetscapes: Many buildings date to the late 19th and early 20th centuries, with ornamental balconies and arcades that evoke colonial grandeur.
- Modern Landmarks: The street’s most iconic structure—11 Diagonal Street—embodies postmodern flair and innovation.
- Barnib House: Situated opposite 11 Diagonal, the blue glass Barnib House is considered one of Johannesburg’s most avant-garde buildings, contributing to the street’s futuristic aesthetic.
The Diamond Building: 11 Diagonal Street
This 22-floor office tower, completed in 1983 and opened in 1984, was originally commissioned by Anglo American and designed by renowned architect Helmut Jahn. Its faceted glass exterior was crafted to resemble a diamond, reflecting the city’s skyline from every angle. Not only is this structure noted for its visual impact, but it also showcased technical advances—demonstrating that reinforced concrete could replace steel for both speed and cost in skyscraper construction.
| Feature | Details |

| Architect | Helmut Jahn |
| Floor Count | 20 (22 levels including base and service) |
| Height | 80 m (260 ft) including spire |

11 Diagonal Street is not only a visual anchor but is featured on cultural artifacts like the Level 42 album cover The Very Best of Level 42. It stands as a testament to Johannesburg’s aspiration and innovation.
The Market Pulse: Trading Life and Cultural Diversity
For over a century, Diagonal Street thrived as a bustling commercial precinct, famed for its markets and vibrant street trade. The area’s unique racial mix—Indian, Chinese, Colored, and White—cultivated a shopping experience like no other in Johannesburg. Traders offered everything from colorful blankets and textiles to traditional artefacts, spices, and fresh produce, making it a major destination for bargain hunters, tourists, and locals alike.
- Migrant Entrepreneurs: Traders—often recent immigrants—built enduring businesses and community ties on Diagonal Street, adapting to shifting zoning laws and economic tides.
- Traditional Markets: Fruit, vegetables, blankets, and fabrics have been staple goods, with market arcades serving as centers of daily commerce and social connection.
- Tourist Appeal: Renovated shopfronts and diverse market culture attracted visitors seeking authentic, local urban experience—especially in contrast to Johannesburg’s suburban malls.
The Johannesburg Stock Exchange Era
In 1978, the Johannesburg Stock Exchange (JSE) relocated its headquarters to No. 17 Diagonal Street, inaugurating a new era for the neighborhood. The Fifth Stock Exchange Building, designed by Monty Sack, was one of the city’s first atrium structures and a centerpiece meant to drive further development westward.
- Stock Exchange Legacy: The move of the JSE was considered transformative, with predictions it would anchor the district for 50–75 years. In reality, the JSE departed for Sandton in 2000 after only two decades, as inner city decline and security concerns prompted the shift.
- Preserved Heritage: The original trading hall at 17 Diagonal Street has been preserved for occasional special events, maintaining a link to the street’s financial history.
The Struggle for Preservation and Redevelopment
As city planning initiatives and urban renewal schemes targeted Diagonal Street, tension grew between developers and longtime tenants, especially market traders. The Group Areas Act of 1950, which enforced racial segregation in urban spaces, designated the area for white redevelopment, disrupting the established multicultural network. In the late 1980s, traders united against pressure to vacate, campaigning for the retention of historic buildings and the preservation of their shops.
- Resistance to Displacement: Indian and other market traders, represented by lawyers, resisted office block developments that threatened their livelihoods.
- Negotiated Conservation: Heritage bodies ultimately secured the retention of two main buildings—Nathanson’s and Carmel—while allowing partial redevelopment, prioritizing the market character over architectural merits.
- Renovation as Attraction: Anglo American’s investment in renovation (R800,000) heightened Diagonal Street’s tourist appeal, drawing both photographers and shoppers to its storied shopfronts.

Modern Diagonal Street is a microcosm of Johannesburg’s transformation and cosmopolitan soul. The area remains lively, colorful, and somewhat chaotic—an ideal canvas for urban exploration and street photography.
