Introduction

Aon Center is the third-tallest skyscraper in Chicago, standing 346 meters tall with 83 floors. Designed by Edward Durell Stone and completed in 1973, it briefly held the title of the world tallest building. The tower is celebrated for its distinctive X-braced exterior and pristine white marble cladding, making it one of the most recognizable landmarks on the Chicago skyline. Its upper floors once housed the Skydeck observation deck offering sweeping views over Lake Michigan and the entire city. The lobby displays rotating contemporary art installations and hosts architectural tours, serving as a key window into Chicago urban development and high-rise engineering history.
