The Transamerica Pyramid is the tallest and most recognizable skyscraper in the San Francisco skyline. 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. Designed by architect William Pereira, at 260 m (850 ft), upon completion it was among the five tallest buildings in the world.
 

The land use and zoning restrictions for the parcel limited the number of square feet of office that could be built upon the lot, which sits at the northern boundary of the financial district. This building was built under the 'Building Codes' to be Earthquake safe.
