The Transamerica Pyramid is the tallest skyscraper in the San Francisco skyline. The building no longer houses the headquarters of the Transamerica Corporation, which moved their U.S. headquarters to Baltimore, Maryland, but it is still associated with the company and is depicted in the company's logo. Designed by architect William Pereira and built by Hathaway Dinwiddie Construction Company, at 853 ft (260 m), on completion in 1972 it was the eighth tallest building in the world.(Wikipedia)
