Which skyscraper in San Francisco was completed in 1972 and designed by William Pereira?

The Transamerica Pyramid is the San Francisco skyscraper completed in 1972 and designed by William Pereira.

Its sharply tapered pyramid form was proposed for the headquarters of Transamerica Corporation. The building’s unusual shape was intended to preserve sunlight and views at street level while providing a large amount of office space.

The tower became an emblem of San Francisco and remained the city’s tallest building until Salesforce Tower was completed in 2018. Its two distinctive “wings” near the top house elevators and mechanical equipment.

The Transamerica Pyramid is not San Francisco’s tallest structure overall; nearby communications structures and later buildings complicate comparisons. In skyline discussions, height may mean architectural height, roof height, or antenna height.
