The Aon Center (200 East Randolph Street, formerly Amoco Building)[3] is a modern supertall skyscraper located in the Northeast corner of the Chicago Loop, Chicago, Illinois, United States. It was designed by architect firms Edward Durell Stone and The Perkins and Will partnership and was completed in 1973[4] as the Standard Oil Building (nicknamed "Big Stan").[5] With 83 floors and a height of 1,136 feet (346 m), it is the fourth-tallest building in Chicago,[2] surpassed in height by the Willis Tower, Trump International Hotel and Tower, and St.Regis Chicago.
The building is managed by JLL, which is also headquartered in the building. Aon Center houses the headquarters of Aon, Blue Cross Blue Shield Association, and Kraft Heinz (BCBS and Kraft Heinz each have a second headquarters, located in Washington D.C. and Pittsburgh respectively);[6] the building formerly served as the world headquarters of Amoco prior to its merger into BP.[7][8][9][10]
The building was briefly the tallest completed building in Chicago, but was soon surpassed by the Sears Tower. It was the fourth-tallest building in the world at the time of its completion.
History
Construction
The Standard Oil Building was constructed as the headquarters of the Standard Oil Company of Indiana. Standard's previous home had been 910 S. Michigan Avenue. This building was constructed in 1911 by the Karpen Brothers Furniture Company and was purchased by Standard in 1927. When the new Standard Oil Building was completed in 1973, it was the tallest completed building in Chicago and the fourth-tallest in the world, earning it the nickname "Big Stan".[11] In 1974, the taller Sears Tower (now Willis Tower) in Chicago surpassed it as the tallest completed building in Chicago (the Sears Tower was also the tallest in the world). However, the Sears Tower had already been topped out in May 1973. When the Aon Center opened as the fourth-tallest completed building in the world, it was only exceeded in height by the twin towers of the original World Trade Center and the Empire State Building in New York City.[12] Originally clad in marble, the Aon Center was also the tallest marble-clad building in the world.[13]
