Aon Center description and facts:
A modern building located in Chicago, Illinois, designed by Architect Edward Durell Stone.

With 86 floors above ground and 5 above ground, it is the second tallest building in Chicago (only Sears Tower), third in the US (it also surpasses Empire State Building) and 15 in the world.

The entire construction was managed by Jones Lang LaSalle. The original name of the building is Standard Oil Building, but in 1985 it was officially changed to Amoco Building. In 2001, the building was sold and eventually named Aon Center.

The tallest building in Chicago from 1973 to 1974. Elevated by Sears Tower.

The highest building in the United States, renamed

During the construction commencement ceremony on April 6, 1970, a helicopter was raised to a height of 346 meters, making the audience realize how tall this building would be.

As a result of the harsh climate, marble began to fall off the walls, which in 1990-1992 was changed to white granite. This renovation cost about 80 million dollars.

Is the highest building in the world without antennas, spiers, etc. on the roof.

In the early eighties, in selected offices, lights were turned off to create a great light cross on the building during Christmas.
