Frederick Law Olmsted’s Jackson Park (including Midway Plaisance and the South Shore Cultural Center)—the designated site of the Obama Presidential Center—tops  Preservation Chicago’s 2018 list of the city’s seven most-threatened architectural treasures.  The annual list puts a spotlight on historic structures and landscapes threatened with demolition in the hope that they can be restored and reused. 

Also on the list, released today, is Helmut Jahn’s 1985 James R. Thompson Center (originally the State of Illinois Center), at 100 W. Randolph. The unique postmodern building has been put up for sale (and possible demolition) by Governor Bruce Rauner.
