U.S. Bank Building (Chicago)

The U.S. Bank Building is a skyscraper located at 190 South LaSalle Street in Chicago, Illinois. It was originally known as the Bank One Plaza and later as the Bank One Tower. Completed in 1969, the building is 69 stories tall and reaches a height of 867 feet (264 meters). It was designed by the architecture firm Skidmore, Owings & Merrill (SOM), and its construction was a significant addition to the Chicago Loop's skyline.

The building's distinctive design features a structural steel frame clad in anodized aluminum and bronze-tinted glass. Its shape is a slightly chamfered rectangle, providing a unique visual profile. The building contains office space primarily and has been home to various major financial institutions over the years, reflecting its location in Chicago's financial district.

The U.S. Bank Building is connected to the Chicago Pedway, a network of underground tunnels providing pedestrian access to nearby buildings and public transportation. Its location is central to many other significant Chicago landmarks. The building is generally considered an example of late modern architectural style and has remained a prominent feature of the Chicago skyline for several decades. Its name changed following the acquisition of Bank One by JPMorgan Chase, and then subsequently when U.S. Bank became a major tenant.
