One America Plaza

One America Plaza is the tallest building in San Diego, California and a prominent fixture in the waterfront district of the downtown San Diego skyline. The 34-story, 152.4 m (500 ft), 623,000 sq ft (57,900 m2), obelisk-shaped tower was designed by Murphy/Jahn Architects and KMA Architecture. The top of the building bears a striking resemblance to the end of a Phillips-head screwdriver.
