Aon Center

Chicago's third tallest building, go in on the opening day, see the panoramic view of Chicago! ! Awesome! The cloud gate of Millennium Park is really smaller than the beans in such a high place, people have become small ants haha

l was passing by and listening to someone else's introduction to the headquarters of the Yi'an Group, which was the tallest in Chicago at the time, and was later replaced by the Sears Building, which was square, simple in shape, but very grand.

怡安中心算是怡安集团的建筑，整个建筑就是摩天大楼，是当时的第一高，非常霸气，推荐看看。

这在芝加哥中心一定要好好的去参观一下怡安中心，挺棒的。

He was the tallest building in Chicago, and later the Hills Building exceeded his height, but it was still very tall. The building is rectangular, white hemp surface, and there is a two-inch hemp slab, which is very distinctive!
