About Aon Center
The Aon Center is a 1,135-foot (346-meter) skyscraper in Chicago's Loop neighborhood, built between 1970 and 1973 by the architecture firm Edward Durell Stone & Associates for the Standard Oil Company of Indiana. With 83 floors, it briefly held the title of Chicago's tallest building after its completion, before being surpassed by the Willis Tower. Today it ranks among the four tallest skyscrapers in the city. The design recalls the former World Trade Center in New York, though the Aon Center is shorter. Originally clad in Carrara marble, the facade was replaced with white granite panels in the early 1990s because of cracking. The entire building serves exclusively as office space and houses no public facilities. The tower is also known as one of the most energy-efficient and environmentally friendly office towers in the United States.

1136 ft. Originally known as the Standard Oil Building, The Aon Center is America's fifth tallest building from base to roof, and sixth by architectural detail. It was built by Standard Oil of Indiana in 1972 by architect Edward Stone. The building was later renamed the Amoco Building when Standard Oil of Indiana rebranded itself. The building was initially faced with marble, but the windy city began to blow the marble off the sides of the building—or so the legend goes. Actually, the Italian Carrara white marble slabs had undergone significant hysteresis as a result of the winter/summer seasonal changing temperature, and the marble was removed as a defensive measure to avoid potential liability from injury and damage if any of the slabs did fall. The entire building was refaced with granite, a costly job at around half of the original cost of the entire building! It is now named after its biggest tenant, the Aon Corporation, a risk management firm.
