About the Observatory
THANK YOU FOR YOUR INTEREST IN THE PROPOSED AON CENTER OBSERVATORY.

This exciting redevelopment project will repurpose space at the top of the Aon Center into an observatory and restaurant. An external elevator system, the tallest and fastest in the country, will be built to service this new observatory. In addition, a family-friendly entertainment venue will be added to the lower level of the Aon Center.

These enhancements will transform a structure that has largely been used for office space into a vibrant destination, attracting an estimated two million visitors annually after a few years of operation, and generating more than $900 million in direct economic impact for the city of Chicago over 20 years.
