Two of Chicago's most treasured architectural landmarks have been impacted by recent torrential rains that have battered the Midwest. 

The Chicago Tribune reports that flooding impacted the SOM-designed Willis Tower basement, which caused a building-wide power outage. The resulting blackout left the 1,729-foot-tall tower completely dark, producing an eerie sight on the otherwise brilliant Chicago skyline.

Have you seen the creepy pictures of Sears Tower sans lights? Flooding knocked out power to the building. Also, I like that people still call it the Sears Tower. Which reminds me, I need to stop at Hooks on the way home from work today. pic.twitter.com/phspRyfVGl

Similarly, rising waters from a river located nearby the Mies van der Rohe-designed Farnsworth House in the western suburbs threatened to overwhelm the glass-encased home, as well. The Chicago Tribune architecture critic Blair Kamin reports, however, that the waters have already subsided somewhat, though additional rains are in the forecast. 

The Farnsworth House, as you’ve never seen it before. Tribune photographer Zbigniew Bzdak captured this dramatic image of flooding at the modernist masterpiece along the Fox River. In this shot, floodwaters actually have receded a bit, in contrast to the shots I posted earlier. pic.twitter.com/UUaCdARy3m

Kamin reports that the house is no stranger to rising tides, however. The home flooded in 1996, taking on over five feet of water.
