Tribune Media announced this week that a Los Angeles developer has purchased the iconic Tribune Tower for $240 million, and that changes are on the way. For the latest installment in our What’s That Building? series, Morning Shift talks to Garrett Karp of the Chicago Architecture Foundation about the history and architectural significance of the 1925 Gothic revival building on Michigan Avenue in the heart of Chicago’s Magnificent Mile. 

We also open up the phones to listeners and hear from WBEZ sports contributor Cheryl Raye-Stout about her father, who worked in the building for more than three decades.
