History of the Aon Center
The history of the Aon Center is a testament to Chicago's dynamic urban development. Originally known as the Standard Oil Building, it was constructed between 1970 and 1973. Designed by architect Edward Durell Stone, the building was initially clad in Italian Carrara marble, making it the world's tallest marble-clad building at the time. This choice of material, however, posed significant maintenance challenges, leading to a major renovation in the early 1990s.
In 1998, the building was renamed the Aon Center after the Aon Corporation, a global professional services firm, became the primary tenant. This renaming marked a new chapter in the building's history, aligning it with one of the world's leading risk management and insurance companies. The Aon Center has since solidified its reputation as a key player in Chicago's business landscape.

The building's original facade featured over 43,000 panels of Carrara marble, giving it a distinctive white appearance.

The new facade features Mount Airy granite, which maintains the building's sleek appearance while providing greater durability.
Standing at 1,136 feet, the Aon Center is the third tallest building in Chicago, surpassed only by the Willis Tower and the Trump International Hotel and Tower.
