Number 3: Transamerica Pyramid in the Financial District, San Francisco
The third tallest building proposed or built, and the second tower building standing in the Bay Area, is the Transamerica Pyramid, the defining icon for the San Francisco skyline since its completion in 1972. With a rooftop height of 853 feet tall, the pyramid would not be surpassed in height until 2018 with the completion of the Salesforce Tower. William L. Pereira & Associates is responsible for the design.
