Info about the US Bancorp Tower from Wikipedia: US Bancorp Tower is the second tallest skyscraper in Portland, Oregon. It stands at 536.0 ft with 42 floors. The building has nearly 740,000 sq ft of office space inside, making it the largest office building in Oregon in terms of volume, and the second tallest building in Oregon, with only the Wells Fargo Center exceeding its height.
The tower was designed by Skidmore, Owings and Merrill (SOM) with Pietro Belluschi as a consultant and built by Howard S. Wright Construction. The tower cost $60 million to construct and was dedicated on December 1, 1983. Originally, the building served as the national headquarters of U.S. Bancorp, and was the regional headquarters of that organization until a 1997 merger moved the corporate offices to Minneapolis, Minnesota.
