The Heller International Building (also 500 West Monroe) is a skyscraper in Chicago, Illinois. The building rises 600 feet in Chicago's Near West Side neighborhood. It contains 45 floors, and was completed in 1992. The Heller International Building currently stands as the 44th-tallest building in the city. The architectural firm who designed the building was Skidmore, Owings & Merrill, the same firm who designed Chicago's Sears Tower and John Hancock Center and the Burj Khalifa in Dubai. The Heller International Building currently stands as the tallest building in Chicago situated west of the Chicago River. One year after its completion, in 1993, the building won the "Best Structure Award" from the Structural Engineers Association of Illinois. The building's design incorporated a unique turret-like structure on the structure's southeastern corner. The turret stands as the building's highest architectural point, and is illuminated in white lights at night.
