Portsmouth Square: A Brief History
Portsmouth Square is often called the birthplace of San Francisco. It was the original town plaza of Yerba Buena, and in 1846 Captain John B. Montgomery raised the American flag there, marking the U.S. claim to the settlement that would soon be renamed San Francisco. Two years later, Sam Brannan is said to have announced the discovery of gold in the square, helping trigger the Gold Rush. The square also holds significance in Black history — it was once the site of California’s first public school, an institution linked in part to William Leidesdorff, an Afro-Caribbean entrepreneur and early civic leader.

By the mid-20th century, the square had become the civic heart of Chinatown — often called “Chinatown’s living room,” a public plaza that hadn’t seen a comprehensive renovation in more than half a century until now. In the late 1950s and early 1960s the square was redesigned as a public park for the Chinatown community, and a pedestrian bridge connecting it to the hotel across Kearny Street was approved in 1970, built that year, and opened in 1971. That bridge, built with feng shui in mind by Chinese American architect Chi-Kwan Chen and funded in part by the Chinese community, became a contested piece of the square’s identity — beloved by some as a community landmark, dismissed by others as underused and shadow-casting.

What’s Happening Now (Demolition Phase)
In June 2026, the city broke ground on the first major renovation of Portsmouth Square in nearly 50 years, closing the park for an estimated two-year renovation. Construction fencing went up June 10, and crews began demolition of the upper and lower plaza levels, including the old clubhouse, while carefully removing and storing public art pieces. The most visible and contested piece: the pedestrian bridge came down in early August 2026, as part of the $73 million park overhaul. City survey data showed 77% of residents supported the bridge’s demolition, though preservation advocates and parts of the Chinese community opposed losing what they saw as a historic, community-funded landmark.

Future Plans
The project is a complete revitalization of the 1.3-acre plaza above the Portsmouth Square garage, funded primarily by the 2020 Health and Recovery Bond, Transit Center Impact fees, the Downtown Park Fund, grants, and a $6 million state allocation, with completion expected in 2028. Removing the bridge alone will add roughly 20,000 square feet of pedestrian space and restore historic sight lines connecting the park to the surrounding neighborhood. Planned features include: Public WorksThe Architect’s Newspaper
- A new two-story, 29-foot-tall, 8,300-square-foot clubhouse replacing the smaller existing one Windnewspaper
- Overhead fixtures designed to support lanterns for Lunar New Year celebrations, plus a solar-topped community clubhouse The Architect’s Newspaper
- A “zero carbon” clubhouse running on 100% renewable energy, along with new lighting, seating, planting, waterproofing, and drainage systems San Francisco Recreation and Parks
Given that your project spans “before demolition” through “during” and presumably into the reopened square around 2028, you’re documenting essentially a full life-cycle transformation of one of the city’s most historically layered public spaces — which gives the series real narrative arc: birthplace of the city → 20th-century Chinatown civic heart → contested modernization.
I’ll keep a project file going so future updates (new photo batches, milestones) build on this instead of starting from scratch — let me know as you add to it.
