Well known in Chicagoland, but perhaps not so well known elsewhere, the Aon Center is a quiet, dignified building in the Chicago skyline. Height and location give its tenants remarkable views in all directions. People facing south look over Grant Park, people with west-facing windows can look at The Loop, people with eastern exposures are treated to Lake Michigan sunrises and boating activities, and people on the northern face get to look up the Magnificent Mile and the Chicago coastline that lead to its northern suburbs.
With 83 floors and a height of 1,136 feet, the Aon Center is the third tallest building in Chicago, surpassed in height by the Willis Tower and the Trump International Hotel and Tower. The building is managed by Jones Lang LaSalle. Aon has the headquarters of the Aon Corporation, and it formerly had the headquarters of Amoco.
