It’s no secret that Illinois is blessed with so many recognizable cityscapes. A multitude of resources were made available to Illinois as it started to rebuild, bringing in the “skyscraper age” and the construction of several landmark buildings in the state.

Continue reading as I take you on a tour of some of the tallest buildings in Illinois.

1. Willis Tower (1,450 ft)

Willis Tower is one of the best Tallest Buildings in Illinois

Skyscraper Willis (formerly Sears Tower) has 1,450-ft height and 110 floors, making it the tallest building in Illinois and the third-tallest in the United States. Fazlur Rahman Khan, a structural engineer, came up with a novel design for this building in which nine individual square “tubes” are arranged in a 33×33 matrix to make a square foundation.

The new layout includes a larger observation deck, so the 103rd-floor Skydeck is now a suitable location for engaging, hands-on museum displays. Also, the Ledge, a glass terrace that extends 4 feet beyond the tower, offers stunning views.

2. Trump International Hotel and Tower (1,388 ft)

Trump Tower International Hotel and Tower, commonly known as Trump Tower Chicago, is a mixed-use skyscraper at 401 North Wabash Avenue on the city’s riverfront that has residences, retail space, parking garages, and a hotel.

The architectural firm Skidmore, Owings & Merrill’s Adrian Smith was responsible for designing the 98-story structure that bears the name of real estate mogul Donald Trump. It opened in 2009 and is one of the tallest buildings in Illinois.

The Standard Oil Building was finished in 1972 and is characterized by a straightforward rectangular design and a tubular steel framework. The tower was the highest marble edifice in the world since it was covered with Carrara marble from Tuscany, Italy, a renowned supplier of construction materials.

The skyscraper’s marble façade was replaced with white granite in the early 1990s after several fractures were found, creating safety concerns; it was the biggest structure in the world to ever undergo re-cladding. After its sale in 1998, the skyscraper took on the name of its largest tenant, the insurance firm Aon, the following year.

5. 875 North Michigan Avenue (1,128 ft)

The John Hancock Center was the previous name for this location. It features an observation deck on the 94th floor and a height of 1,128 ft. One of the world’s highest structures, it was completed in 1969.
