Los Angeles - US Bank Tower (formerly First Interstate Bank World Center)

With its pyramidal tower, the Central Library represents a mixture of Beaux Arts and various oriental styles.
Completed in 1990, the First Interstate Bank World Center is one of the world's twenty-five tallest buildings, and the tallest on the west coast of the United States, at 1018ft/310m. It also has the dubious distinction of being the tallest building located in a seismic zone 4. Sale of the air rights around the Central Library to the tower's developers provided the library with the necessary funds for its recent restoration.
