Once upon a time, the tallest building in the country was right here in Illinois, specifically Chicago. Today, One World Trade Center in New York City has the distinction as the tallest skyscraper in the United States, but that accolade once belonged to the Sears Tower in Illinois. Now known as Willis Tower, the Sears Tower is an incredible feat of engineering, especially during the time it was built.

The year was 1970 when the ground was broken in downtown Chicago and construction began on what would become the world's tallest building. This was the new home for Sears Roebuck and Company at the time.

The building was completed in 1973 and its Skydeck was opened as well that year. It had taken over 2,000 workers over three years to complete construction.

In 1984, the iconic broadcast antennas were added to the top of the 110-story tower giving it its striking appearance.
