This is the facade of Marina City, which consists of two corncob-shaped towers. I love architecture and this iconic building in Chicago is one of my favorites.
The bottom 19 floors form an exposed spiral parking ramp. The 20th floor contains a laundry room with panoramic views, while floors 21 through 60 contain apartments. These apartments are unique in having almost no interior right angles. A 360-degree open-air roof deck lies on the 61st and top story.
