Author NiNi Harris' new book, This Used to Be St. Louis, tells the story of our 90 places in our city that have seen great change. From the Church of Scientology mansion that's become Saint Louis University's Office of Admissions to the historic Chinatown (once known as Hop Alley) that's become Spire Energy's headquarters, Harris walks the reader through the layers of history, one place at a time.

Buy your own copy online or meet the author at the Carpenter Branch of the St. Louis Public Library on Saturday, July 7. She'll be giving a talk about the book at 7 p.m.
