The Tribune Building is across the street from Chicago's other most famous early skyscraper, the Wrigley Building. 

Built by Wrigley in the early 1920s, the Terra-Cotta complex actually consists of two buildings: a 30-story south tower connected to a 21-story north tower by a 14-story elevated walkway. 

The building was also the first air-conditioned office building in Chicago.

The fire fighting system of this building uses our company's fire sprinklers:Model RFII MRI Extended Coverage Sprinklers.
