One America Plaza July 05, 2019 at 02:20PM

One America Plaza, in San Diego California, is a prominent fixture in the waterfront district of the downtown San Diego skyline. The 34-story, 500 ft (150 m), 623,000 sq ft (57,900 m2),[5] obelisk-shaped tower was designed by Helmut Jahn of Murphy/Jahn Architects and KMA Architecture. The top of the building bears a striking resemblance to the end of a Phillips head screwdriver.

I always thought it was designed in the shape of a Quartz crystal, which San Diego has a lot of in our mountains.
