Transamerica Pyramid

The Transamerica Pyramid is 853 feet and 48 storeys, designed by William Pereira and completed in 1972. The taper was chosen so daylight would still reach the street. Two wings at the top hold the elevator machinery and a smoke evacuation tower. The 27th-floor observation deck closed to the public in 2001; the half-acre Redwood Park at the base is still open.

The Shape the City Hated

The Transamerica Pyramid opened in 1972 and the city spent years trying to stop it. Critics found a way to work the architect's surname into a nickname no guidebook will print, and a petition to halt the project gathered thousands of signatures before a single panel went up. People did not want a pyramid in San Francisco. They wanted the flat-topped skyline they already knew, and the argument over the shape ran for nearly a decade. The reason it tapers turns out to be the least glamorous one possible: a tower that narrows as it climbs throws a far smaller shadow than a slab of the same height, so daylight still reaches the street. That was the case Transamerica's leadership made for the design William Pereira drew. Fifty years later, the architecture critic John King called it an architectural icon of the best sort, one that fits its location and gets better with age. **Stand at the corner of Clay and Montgomery and look up.** Look at the way the four faces taper to the point.

Frequently asked

How tall is the Transamerica Pyramid?
853 feet across 48 storeys. It was the tallest building in San Francisco from its completion in 1972 until Salesforce Tower overtook it in 2017, and it remains the more recognisable of the two by a wide margin — the outline works at postcard size, which no rectangular tower manages.
Why is the Transamerica Pyramid shaped like a pyramid?
So daylight would still reach the street. A tower that tapers casts a far smaller shadow than a slab of the same height, and that was the argument Transamerica's leadership made for the design. The narrowing floor plates also stack neatly around a central elevator core.
Can you go up the Transamerica Pyramid?
Not to the top. The 27th-floor observation deck was open to the public and free, but it closed in 2001 and the upper floors are private offices. The lobby and Redwood Park at the base are open, and the park is the better stop anyway.
What are the two wings at the top of the Transamerica Pyramid?
They are working structures, not ornament. One encloses the top of the elevator shafts; the other is a smoke evacuation tower for firefighting. Because neither is a decorative cap, the point you see from the street is the actual crown of the building.
Where is the best place to photograph the Transamerica Pyramid?
Not from directly beneath it. Walk east on Clay Street, cross Columbus Avenue and turn around: the tower rises through the gap between low brick storefronts, and the contrast between a 1970s corporate tower and a 1920s street tells you more than either does alone.
