However, it did break the record of the world’s highest residence surpassing the John Hancock Center which held the record since 1969.

Aon Center (Tallest Building Chicago)

The Aon Center is an iconic Chicago landmark that you wouldn’t want to miss. A brainchild of a partnership between architect firms Edward Durell Stone and The Perkins and Will, it is one of the tallest buildings in Chicago. It marked its addition to the Chicago Skyline in 1974 and It was originally designed as the headquarters of the Standard Oil Building of Indiana. This 83-floor skyscraper reaches up to 1,136 ft and is the fourth largest building in Chicago.

Initially, it was the world’s largest marble-clad building, encased with 43000 Italian Carrara marble slabs. This design decision later proved to be fatal as the Windy City blew a 350-pound slab during construction. To keep the marble slabs in place stainless steel straps were utilized but later the entire building was refaced with white granite. For this around $80 million were spent, almost half of the original building’s cost. In 2018, plans for constructing an observation deck featuring a thrill ride were introduced and it was expected to be completed in 2022 but the construction was delayed a year due to the pandemic.
