Chicago architecture is big, a sight for sore eyes, and known the world over. The city is also considered to be “the birthplace of the American skyscraper.” So, when you think of Chicago architecture, Willis Tower stands out in this Windy City.

What was first known as the Sears Tower is iconic in the heart of America. “At 110 stories high, Willis Tower is also one of the largest skyscrapers in the world,” according to willistower.com. When it was completed with help from more than 2,000 workers in 1973, it was the world’s tallest building.

Previously Known as Sears Tower

You really can’t talk about Chicago architecture history without mentioning Willis Tower and its importance overall. Back in 1969, Sears Roebuck and Company was the bigwig of retailers and the world’s largest at that. With roughly 350,000 employees, the company needed a large enough office for many of those staff members. Architects Skidmore, Owings, and Merrill were commissioned for the design of the building while, “Fazlur Khan, the structural engineer, designed the ‘bundled tube’ design that handled both wind and gravity,” according to The Sky Deck.

Interesting and Cool Facts about Willis Tower

Ground broke in 1970, and the building took three years to complete. According to Skydeck, “The builders used enough concrete to make an eight-lane highway five miles long.” Some other cool and fun facts about the building include that it has:

• 25 miles of plumbing
• 1,500 miles of electric wiring
• 80 miles of elevator cable
• 796 restroom faucets
• More than 145,000 light fixtures
• 12,000 construction workers, Sears employees, and Chicagoans signed the last beam put in place

The Sears Tower name continued even after Sears Roebuck and Company sold the building and moved in 1988. It wasn’t until 2009 that it was renamed after London-based insurance broker, the Willis Group.

According to Willis Tower, some additional interesting details through the years include:

• In 1982 the broadcast antennae were added.
• In 1985, Wacker Drive Atrium was added to base of the tower, featuring arched glass.
• In 2000, Skydeck, the observation deck on floor 103, was renovated for the first time.
• In 2009, Sears Tower became Willis Tower.
• In 2015, Blackstone bought Willis Tower.
• In 2017, a five-year renovation began.
• In 2022, renovations were completed, which included Art of the Neighborhood and a rooftop greenspace.

Willis Tower is so ingrained in Chicago architecture along with other spectacular buildings. Not only is the city home to some of the world’s most unique skyscrapers but “Chicago structures also feature a range of genre-defining styles,” according to Chicago Architecture Cruises & Tours (The Ultimate Guide). There is such a diversity of styles in the city, making it a great destination for anyone who wants to be inspired by Chicago architecture.
