The Chicago Tribune Tower was built in the 1920s. The old
Tribune Building was located on the southeast corner of Dearborn
and Madison streets.
The Chicago Tribune was originally headquartered in a 1902
building at Madison and Dearborn Streets. After moving to its new
tower on Michigan Avenue in the 20s, the original Tribune Building
later became known as the First Federal Building. It was razed in
2001 to make way for the construction of One South Dearborn, a
40-story tower set to open in 2005.
