Portsmouth Square, San Francisco — Visitor Guide & Things to Do Nearby

Portsmouth Square is where San Francisco began. Originally called Plaza de Yerba Buena in the early Mexican settlement, it was renamed after the USS Portsmouth, the American ship that captured the town and raised the first American flag here in 1846. This small plaza has witnessed an extraordinary number of firsts. In 1847, California's first public school was erected on its southwest corner. In 1848, Sam Brannan stood here and announced the discovery of gold, igniting the Gold Rush that transformed California and drew hundreds of thousands of people to San Francisco. During the 1906 earthquake and fire, the square served as a gathering point for displaced residents, a temporary tent city, and even a makeshift cemetery. It has been the heart of the community through triumph and disaster. In the early 1960s, the original plaza was removed entirely to build the Portsmouth Square Garage underground. The redesigned surface plaza, created by landscape architects Royston, Hanamoto, and Mayes, features curved tiled roofs and red columns that reflect Chinatown's cultural heritage. Today, Portsmouth Square is known as the "Heart of Chinatown." On any given morning, you will find elderly residents practicing tai chi, playing chess, or simply gathering to socialize. It is a living community space that connects San Francisco's oldest history with its most vibrant present. A Questo quest through Chinatown uses Portsmouth Square as a key waypoint, connecting Gold Rush history with the neighborhood's Chinese American heritage.
