怡安中心評價

The third tallest building in Chicago, on Open Day, you can see the panorama of Chicago. It's great. The Cloud Gate of Millennium Park is really smaller than beans in such a high place. People become little ants.

The headquarters of Aon Group was the tallest building in Chicago when it was completed. It was replaced by Sears Tower. The building was square, simple but magnificent.

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 Hills Tower surpassed his height, but it was still very tall. The building is rectangular, with a white stone surface and a two-inch thick Flagstone slab.

More than 300 meters of buildings are now one of the highest in Chicago, with no extra wires and lightning rods to make the net height more technical. The huge dark glass curtain wall with white stone wraps the whole square building. It is said that it was created in 1992 when it was renovated. The 80-storey office building is also the office choice of many famous international enterprises.
