Released on July 11, 2025

Introduction

In this bonus episode of 99% Invisible, host Roman Mars takes listeners on an architectural and cultural journey through his beloved city, San Francisco. Partnering with GetYourGuide, Mars explores iconic landmarks, hidden gems, and shares personal anecdotes that highlight the intricate design and history shaping the city's landscape.

The Transamerica Pyramid: From Controversy to Iconic Status

Roman Mars begins his guide with the most recognizable structure in San Francisco—the Transamerica Pyramid. Designed by Los Angeles architect William Pereira, this 850-foot-tall, four-sided pyramid with distinctive "ears" housing the elevator shaft and stairwell, has long been a subject of debate among locals.

• Initial Controversy: When proposed, many local architects criticized the building as a mere advertising symbol rather than a functional modern structure. Critics felt it violated zoning and urban planning principles, especially in an area dominated by three-story buildings. Assemblyman John Burton famously declared, "The pyramid would rape the skyline" [02:45].

• Evolution of Perception: Over fifty years, sentiments shifted. The San Francisco chapter of the American Institute of Architects, initially opposed, later hailed it as one of the city's best buildings. Late architect Henrik Bull, once a vocal critic, described the pyramid's beauty from Columbus Avenue, noting, "It perfectly completes the scene" [05:30].

• Architectural Significance: Mars emphasizes the Transamerica Pyramid's role as both a corporate headquarters and a company logo—a dual-purpose design that was ahead of its time. Despite Transamerica relocating its headquarters to Baltimore, the pyramid remains integral to the company's branding, featured in their 2025 refreshed logo [04:15].

Public Spaces and the Rise of POPOS

Transitioning from iconic buildings, Mars delves into the concept of POPOS—Privately Owned Public Spaces—that dot downtown San Francisco.

• Definition and Purpose: POPOS are publicly accessible plazas, terraces, atriums, and parks maintained by private developers. They are marked by signs indicating their public status and operating hours, a requirement from the 1985 Downtown Plan mandating that new large-scale projects allocate 1% of construction costs to public art [06:50].

• Success Factors: Jamie Lasher, Mars's tour guide from GetYourGuide, shares insights from urban sociologist William Whyte, highlighting four elements that make public spaces successful: sunlight, movable seating, proximity to food, and opportunities for people-watching [09:11].

  Jamie Lasher: "Movable seating, food, sunlight, and fascinating people to watch. So the current tallest building in San Francisco is Salesforce Tower."

• Challenges and Limitations: While POPOS aim to enhance public life, Mars points out their limitations. Being privately owned, these spaces often come with restrictions—security guards, limited hours, and surveillance—that can deter free public use. Additionally, locating and accessing all POPOS requires online guides, underscoring the need for genuinely public spaces [07:40].

Salesforce Tower and the Millennium Tower: Contrasting Architectures

Mars contrasts two of San Francisco's tallest buildings: Salesforce Tower and Millennium Tower, examining their architectural impact and structural integrity.

• Salesforce Tower: At the time of release, Salesforce Tower stands as the tallest building in the city. Mars critiques its bulky appearance, though he acknowledges its stunning rooftop park.

  Roman Mars: "Its slender silhouette is elegant as seen from the East Bay. It is a joy to drive over it. It is a joy to walk over it." [10:30]

• Millennium Tower: Known colloquially as the "Leaning Tower of San Francisco," this residential skyscraper has suffered from significant structural issues, including uneven settling that has caused noticeable tilting.

  Jamie Lasher: "If you drop a marble on the floor of one of the condos, it'll roll." [14:07]

  Despite extensive repairs costing $130 million and ongoing litigation, the building continues to face challenges, highlighting the complexities of constructing high-rise buildings on San Francisco's unique landfill foundations [15:00].

Hidden Historical Gems: The Vanishing Statue on Mount Olympus

Venturing beyond modern architecture, Mars shares the intriguing story of a lost statue once prominent atop Mount Olympus.

• Triumph of Light: Erected in 1887 by developer and future mayor Adolf Sutro, this 12-foot bronze statue symbolized liberty and progressivism. Dedicated on Thanksgiving Day, Sutro envisioned it as a timeless beacon for civilization and philanthropy.

  Roman Mars: "May the light shine from the torch of the Goddess of Liberty to inspire our citizens to good and noble deeds for the benefit of mankind." [19:45]

• Sudden Disappearance: By the late 1930s, the statue had gained the moniker "the mystery monument" and was eventually removed in the 1940s due to structural decay and neglect. Today, only the stone pedestal remains, leaving the story of its disappearance shrouded in mystery [20:30].

The Golden Gate Bridge: A Testament to Human Ingenuity and Safety

Concluding his guide, Mars pays homage to the Golden Gate Bridge, celebrating it as the greatest piece of human-made infrastructure.

• Engineering Marvel: Designed by Chief Engineer Joseph Strauss with significant contributions from Charles Alton Ellis, the bridge is admired for its elegant silhouette from every vantage point.

  Roman Mars: "It is just a gorgeous thing." [22:50]

• Commitment to Safety: Strauss prioritized worker safety, implementing mandatory clip-on safety lines and investing $130,000 in an elaborate safety net that saved 19 lives during construction. This net also fostered camaraderie among workers, known as the "Halfway to Hell club" [24:00].

• Cultural Impact: Beyond its functional brilliance, Strauss was also a poet. Mars recites a portion of Strauss's poem celebrating the bridge, encapsulating its grandeur and symbolic significance.

  Strauss's Poem: "The mighty task is done. Resplendent in the western sun, the bridge looms mountain high..." [25:15]

Conclusion

Roman Mars's Guide to San Francisco offers an insightful exploration of the city's architectural landmarks and public spaces, blending historical narratives with personal reflections. From the initially divisive Transamerica Pyramid to the enduring elegance of the Golden Gate Bridge, Mars highlights how design and intent shape the urban experience. This episode not only celebrates San Francisco's visible structures but also delves into the stories and controversies that render them more than mere buildings—they are symbols of the city's evolving identity.
