Buried time capsule discovered under Transamerica Pyramid sheds light on San Francisco’s history
It began with a tip–an email from a San Francisco resident who had read The Secret, Byron Preiss’s 1982 book about hidden treasures. That message set off a chain of events that led to a 1974 building plan drawn by architect William Pereira, a visit to an underground pump room, and the eventual discovery, beneath six feet of concrete, of a long-lost time capsule buried deep within the Transamerica Pyramid.
The capsule, a 14-by-16-inch metal cylinder, was unearthed during a recent renovation of the building. Buried in 1974, it offers a glimpse into life in San Francisco during the tower’s construction and reveals key details about the project itself. Its contents will be displayed in a new exhibit curated in partnership with Foster + Partners opening May 18 in the building’s lobby.
The capsule was located based on an email tip and a 1974 building plan labeled “Time Capsule” drawn by architect William Pereira.The capsule, a 14-by-16-inch metal cylinder, offers a glimpse into life in San Francisco during the tower’s construction and reveals key details about the project itself.When the Transamerica Pyramid officially opened in 1972, it was hailed as a symbol of the city’s growth and ambition. Local media buzzed with anticipation. Two years later, as the Transamerica Corporation moved out of the building, the company assembled the capsule’s contents and commemorated its burial with a celebratory event. A plaque was installed above the site, instructing that the capsule remain untouched for 50 years. As decades passed and renovations altered the building’s layout, the plaque disappeared—and the capsule wasforgotten.
That is, until the email tip arrived. Fifty years after it was buried, just ahead of when it was intended to be opened, the capsule was located.
This flyer was circulated in 1969 to stop the Transamerica Pyramid’s construction. It was among the objects inside the time capsule.The timing of its burial coincided with a chaotic chapter in San Francisco’s history. In 1974, Mayor Joseph Alioto’s wife mysteriously vanished, only to reappear two weeks later claiming she’d staged her disappearance to punish him for ignoring her. Around the same time, 19-year-old heiress Patty Hearst was kidnapped at gunpoint by members of the radical Symbionese Liberation Army. The Transamerica Pyramid too made headlines: The San Francisco Chronicle dismissed it as “the world’s largest architectural folly,” and the city’s own planner derided it as “an inhumane creation.”
These turbulent moments, and the spirit of the era, were captured in the time capsule’s contents, along with a recipe for Pisco Punch, the famed cocktail invented at the nearby Bank Exchange Saloon. Once buried and nearly forgotten, the capsule now takes center stage in a curated exhibit in the building’s lobby, offering a vivid snapshot of a city in the midst of transformation.
“Through moments of prosperity and periods of challenge, the Transamerica Pyramid has stood tall as one of the iconic silhouettes of San Francisco’s skyline. I see it now not just as a symbol of bold design, but of resilience–for this neighborhood, and for our city,” said San Francisco Mayor Daniel Lurie. “Fifty years from now, my hope is that we will look back on this era–this exact moment in time–as the beginning of a new chapter for San Francisco,” he added.
Opening to the public on May 18, the exhibition aims to honor the legacy of the Transamerica Pyramid while highlighting the design of its recent renovation.SHVO and Deutsche Finance America purchased the Transamerica Pyramid in 2020 for million, pledging to preserve its historic legacy. In 2024, the landmark reopened following extensive renovations by Foster + Partners, marking a major step in the broader revitalization of downtown San Francisco, which had been deeply impacted by widespread office closures during the COVID-19 pandemic.
“This exhibition serves as a reminder of the significance of the Transamerica Pyramid as a global icon since its inception more than a half century ago,” said Michael Shvo, chairman and CEO of SHVO. “By sharing the contents of the time capsule publicly, as a thoughtfully designed exhibition, we are honoring Transamerica Pyramid’s legacy and seamlessly complementing our meticulous remastering.”
