Although many people believe that the John Hancock building is the second tallest in Chicago, the title actually belongs to the Aon Building by a mere 9 feet over the Hancock, coming in second only to the Sears Tower.

Built in 1972, this building originally housed the corporate employees of Standard Oil which became Amoco and then BP (British Petroleum) and is now the corporate headquarters for Aon. The building was originally clad in expensive Carrera marble until it started to fall off the building. You can now find some of it used as very expensive landscaping stone near the BP refinery in Whiting, Indiana as well as other BP facilities throughout the area.

Unless you know someone who works here you probably won't be able to go up to the top for the view but you can at the 1st and 3rd tallest buildings in Chicago, the Sears Tower and the John Hancock.
