Marker Inscription
The birthplace of a great city. Here, June 25, 1835, William A. Richardson founder of Yerba Buena, (later San Francisco) erected its first habitation, a tent dwelling, replacing it in October 1835, by the first wooden house, and on this ground, in 1836, he erected the large adobe building, known as "Casa Grande".

The Story
On June 25, 1835, William A. Richardson pitched a tent dwelling on this spot in Mexican-era California, the first habitation of the settlement he named Yerba Buena. He soon replaced it with a wooden house and, in 1836, the substantial adobe known as "Casa Grande." From this modest beginning grew the city that would become San Francisco.
Why it matters
This ground marks the literal founding of San Francisco, a cornerstone of American westward settlement on the Pacific.
The story behind this marker
AI contextThe era
In 1835, when this ground first held a dwelling, the great bay here belonged to Mexican California — a far northern frontier of a young Mexican republic, thinly settled and remote from any center of power. The magnificent harbor that would one day anchor a major city was, at that moment, mostly empty shoreline.
This was the era of the early Republic in the United States and of a wide-open Pacific frontier where nations, traders, and settlers all took an interest. Hide-and-tallow ships worked the California coast, and a handful of newcomers were beginning to put down roots among the ranchos and missions.
Into that quiet setting came the first permanent habitation on this spot — a tent, then a wooden house, then something more lasting. It marks the moment when an empty cove began, almost imperceptibly, to become a town.
People & events
The marker credits William A. Richardson as the founder of Yerba Buena, the settlement that would grow into San Francisco. On June 25, 1835, he raised the first habitation here — a simple tent dwelling — a beginning about as humble as a great city's could be.
He did not stop there. That October he replaced the tent with the first wooden house, and in 1836 he built on this same ground the substantial adobe that became known as "Casa Grande." In the space of little more than a year, the site went from canvas shelter to solid, permanent home — the physical seed of a settlement.
That progression is the story in miniature: a place claimed, then made permanent, then built up in earnest. Richardson's buildings gave the future city its first fixed point, the address from which everything else would spread.
Its place in the American story
San Francisco became one of the great cities of the American West and a defining gateway on the Pacific, and this marker fixes the precise spot where it began. Long before the Gold Rush brought the world rushing in, the town already existed in embryo, thanks to that first dwelling of 1835.
The site captures a pivotal transition in the American story. It was founded in the Mexican era, under Mexican California, and only later did the settlement pass into American hands and take the name San Francisco — a single piece of ground that lived through the larger shift of the Southwest and Pacific coast into the United States.
It is also a reminder of how westward settlement actually worked: not as a single dramatic event, but as one person raising one shelter, then a house, then a larger building, until a place existed where none had before. From this modest founding grew a metropolis.
If you visit
You'll be standing on what a marker calls the birthplace of a great city — a startling claim to plant on any single patch of ground, and worth pausing over. Picture the sequence: a tent in June, a wooden house by autumn, a broad adobe within the year.
The fun of this stop is the collision between then and now. The city that surrounds you today rose from that first tent, and the marker asks you to hold both images at once — the empty cove and the crowded streets that replaced it.
If you're exploring the city's oldest quarter, make this the anchor of your walk and let the founding date orient everything else you see. From here, the whole sprawling story of San Francisco unrolls outward, all of it tracing back to one man's decision to stay.

Fire Fighter's Memorial
San Francisco, CA
This memorial honors the volunteer firefighters who guarded Gold Rush–era San Francisco from 1849 to 1866, when the booming city was a tinderbox of wooden buildings repeatedly swept by devastating fires. It was funded by a bequest from Lillie Hitchcock Coit, a colorful benefactor famously devoted to the city's firemen, whose generosity also raised Coit Tower. Erected in 1933, it looks back with affection on the rough-and-ready men who fought the flames of a young metropolis.
Down to the Seas in Ships

These sleek, fast vessels carried the goods and dreamers that transformed a frontier port into a booming city.
