  Aon Center, Chicago

Favorite thing: In the Loop neighborhood downtown (on 200 East Randolph Street) stands the modern skyscraper known as the Aon Center. It was the tallest building in Chicago in the years 1973 and 1974; once the Sears Tower was complete, it lost that honor. However, it still is the tallest building in the United States to ever change its name. For a long time, it was known as the Amoco Building and then the Standard Oil Building.
Although it is basically a straight up and down skyscraper, it still has character. A sunken plaza leads to the main entrance off of East Randolf Street, which makes it interesting for we "mere" humans to gaze upward in awe of what man is capable of producing.
Aon Center is over 300 meters tall, and it is the tallest building in the world that does not have any major spires or finials at the top.
Each side of the building has 15 vertical bands of black recessed between triangular white piers.
Unfortunately, the original marble facade had to be removed for safety reasons. This was Carrara marble from Italy! They ground the marble up and used it to surround many Amoco refinery properties, including the Amoco refinery in Whiting, Indiana.
Standard Oil Company developed the property, and today it is owned by Wells Real Estate Investment Trust, Inc.

Fondest memory: I first took note of the Aon Center because my daughter Jill worked there for more than a year. I was impressed with the wonderful views that businesses in the center have, whether it's the city skyline, the lake, or the Chicago River. It has 83 floors of unobstructed viewing.
The beautiful sunken area and water features are beautiful. There are places to eat in that area with outdoor seating, which is quite pleasant.
I took the photograph while in Millennium Park near the Jay Pritzker Pavillion and Great Lawn.
