• Stories: 41
• Maximum Height: 575 feet / 175 meters

• The building that used to be on this site was the John Crerar Library. The 14-story building was erected in 1920 and designed by Holabird and Roche.
• One of the bogus "facts" sometimes presented by Chicago tour guides is that this building's sloping roof was designed to keep it's shadow from falling on a beach. This is incorrect. There isn't a beach anywhere near this building. There was a controversy over a building on Lake Shore Drive casting a shadow on the Ohio Street Beach in 2006, but that building was erected anyway with no alterations to its plan.
• The top five floors of this building are empty and are not included in its official floor count.

• Three years after its completion, this building played a central role in the film Adventures In Babysitting.

  It is so immediately recognizable as Chicago's skyline. We're lucky to have it. I also like the the urban myths that accompany it. Makes adults giggle. We need more of that--giggling, of course.

  It's a beautiful building on the inside also. If your one of the lucky who've had a chance to work in the building, the view from the top floors overlooking the lake is beautiful.

  Not only in Adventures in Babysitting, but this building is also rapidly showed in Cheaper by the Dozen.

  I agree with Franz Hursker, because every time I go downtown, I get overwhelmed and excited!

  One of my favourite Chicago buildings. I always look forward to seeing it when I visit.

  This building with its diamond shaped top does stand out as you travel the lake front. When traveling into the city with first time visitors, they always comment on the building with the unusual roof. So I guess the designers accomplished one goal in drawing attention to it.

  This is the best skyscraper in Chicago with it's slanted diamond shaped roof, you can see it from the planetarium, as a great skyline addition for Chicago.

  On April 30, 2006, I went to a wedding in the One Prudential Plaza. I had a great view of what I often call the "Adventures in Babysitting Building". I was really excited after I read the "Did you know" section about this building.
