Look up at this thing. The Transamerica Pyramid is one of those buildings that makes you wonder what was here before — and the answer is one of the wildest stories in San Francisco.
This exact spot was once home to the Montgomery Block, built in eighteen fifty-three. At the time, it was the tallest building west of the Mississippi. It wasn't just big — it was the intellectual heart of the city. Mark Twain worked here. Robert Louis Stevenson hung around. Sun Yat-sen, the future founder of the Republic of China, had an office in the building where he plotted revolution. The Montgomery Block was where San Francisco's writers, artists, and radicals came to think dangerous thoughts.
And it was tough. When the eighteen-oh-six earthquake leveled most of the city, the Montgomery Block survived. It stood for over a hundred years. And then, in the nineteen fifties, it was demolished. Not for another grand building. For a parking lot. A flat, empty parking lot that sat there doing nothing for ten years. One of the most historically significant buildings in the American West, replaced by asphalt.
Then came the Pyramid. Architect William Pereira designed it in the late nineteen sixties, and the shape wasn't just for show. The tapered pyramid form was specifically chosen to cast less shadow on the surrounding streets. San Francisco's downtown was getting darker as towers went up, and Pereira's argument was that a pointed building lets more light reach the ground than a flat-topped box of the same height.
People were furious when it went up. Critics called it an abomination, a dunce cap, a spike driven into the heart of the city. Now, of course, it's beloved. It's on every postcard. Funny how that works with buildings that dare to be different.
