Probably the most iconic building in San Francisco is the Transamerica Pyramid. It is also probably one of the more unique looking buildings in the United States and is easily recognizable.
Construction on the building began in 1969 and was completed in 1972. It faced considerable opposition during it's construction and was sometimes known as Pereira's Pike after the designer. Until 1974 it was the tallest skyscraper west of the Mississippi.
The building stands 850 feet tall.
Right next to is a park where they planted some redwood trees.

I'm not sure what kind of flower this is but I like the effect.
There is also a fountain with bronze frog statues. Many of them are in playful poses.
