The Transamerica Pyramid is located in the heart of the Montgomery Financial District at 600 Montgomery Street in San Francisco, California. It is a part of Transamerica Center (a complex that includes Two Transamerica Center and Transamerica Redwood Park) and encompasses nearly one city block. The Transamerica Pyramid building and logos featuring it are registered trademarks of Transamerica Corporation.
The building is evocative of San Francisco and has become one of the many symbols of the city. Designed by architect William Pereira, it faced considerable opposition during its planning and construction, and was sometimes referred to by detractors in derogatory slang.
