The Transamerica Pyramid is the tallest skyscraper in the San Francisco skyline and one of its most iconic. Although the building no longer houses the headquarters of the Transamerica Corporation, it is still strongly associated with the company and is depicted in the company's logo.
The Sentinel Building, designed by Salfield and Kohlberg, is a flatiron building clad in white tile and copper. Construction was begun before the 1906 Earthquake and Fire. The framing survived the disaster, and the building was completed in 1907. The top floor housed the real estate brokerage of Political boss Abe Ruef after his release from San Quentin State Prison on charges of graft.
