JPMorgan Chase Tower

The 75-story, 305.4 m (1,002 ft) tall JPMorgan Chase Tower of Houston, Texas, formerly the Texas Commerce Tower, is the tallest building in Texas, the tallest five-sided building in the world, and one of the world's tallest structures.

The tower was built in Downtown Houston at 600 Travis Street in 1981 as the Texas Commerce Tower. It was designed by noted architects I.M. Pei & Partners. The local architect and architect of record is 3D/International. In some early plans, the building reached up to 80 stories; however, the FAA expressed concern that additional height was a risk for aircraft going into and out of nearby William P. Hobby Airport.

Upon its completion, the building surpassed Aon Center in Los Angeles to become the tallest building in the United States west of the Mississippi River, a title it held until Los Angeles' Library Tower, now known as the U.S. Bank Tower, was built in 1990.
