Twenty-five years It overtook the World Trade Center in New York City to become the highest building in the world when it was completed in 1974, a record it maintained for nearly 25 years; it was also the tallest structure in the Western Hemisphere for 41 years, until the new One World Trade Center surpassed it in 2013. The Sears Tower is currently the 4th tallest building in the United States and the third tallest building in Illinois.
Its height makes it eligible for inclusion in several top 10 lists. It is the only building in America that can be seen from both the Atlantic Ocean and the Pacific Ocean. The tower also has the distinction of being the first building to be mentioned by name in the novel The Adventures of Tom Sawyer. In the book, Mr. Dobbins takes young Tom to have a look at the "new big store" being built across the river, which turns out to be the Chicago World's Fair (1893).
The tower is located at 600 Lake Street in Chicago, Illinois. It replaced the Merchandise Mart as Chicago's tallest building and its second largest building after the John Hancock Center. The Sears Tower has 49 floors above ground and an additional 7 floors below ground. The total floor area is about 5 million square feet (480,000 m²), making it the largest office space building in the world. There are 1,100 parking spaces beneath the building, most of them valeted.
When it was finished in 1972, 1 World Trade Center was the tallest skyscraper in the world for two years, eclipsing the Empire State Building after a 40-year reign. The North Tower was 1,368 feet (417 meters) tall and contained a 362 foot (110 meter) telecommunications antenna or mast constructed on the roof in 1978. The South Tower was 1,344 feet (411 meters) tall.
In addition to being the tallest building in New York, 1 World Trade Center was also the second fastest building ever built at the time of its completion. The building took only 11 months to complete instead of the usual 12-13 months.
It should be noted that this ranking is not necessarily indicative of which building is the greatest, but rather which building was created first. There are several other buildings that are taller today than 1 World Trade Center was back then. However, if you include the antennas, the North Tower held the record for longest free-standing structure in the world until 2009 when the Shanghai International Financial Center was completed with a height of 2,732 feet (853 m).
1 World Trade Center was also the most expensive building ever erected before breaking its own record twice over. The total cost of construction was $140 million (1969 dollars), almost $500 million in today's money. It remains the largest single contract price ever awarded at the time it was completed.
The Twin Towers—the original 1 World Trade Center (the North Tower), at 1,368 feet (417 m), and 2 World Trade Center (the South Tower), at 1,362 feet (415.1 m)—were the highest structures in the world at the time of their construction. (1973-2001) The World Trade Center (WTC)

For more than three decades, the CN Tower was the highest building, tower, or freestanding structure in the world. It is still the highest structure in the Western Hemisphere. Over the years, Guinness World Records have featured the World's Tallest Free-standing Structure (1975). The CN Tower was again voted World's Most Popular Theme Park in the 2012 worldwide poll of readers of Condé Nast Traveler.
The SkyDome, now known as Rogers Centre, was once declared the world's tallest building when it was under construction. But on September 28, 1973, the CN Tower was opened with President Nixon in attendance. It was later surpassed by Taipei 101. Today, the CN Tower remains the most popular attraction in Toronto and one of the top attractions in North America.
The CN Tower stands 348 m (1168 ft) tall and holds the title of highest building in Canada and of the Western Hemisphere. Its height makes it easily visible from many places in Toronto and its proximity to the city center makes it a must-see destination for tourists.
For four decades, Chicagoans had been able to outperform New Yorkers on at least one metric: the City of the Big Shoulders has the highest skyscraper in the country. However, as of Tuesday, the crown is shifting eastward. One World Trade Center in Lower Manhattan is now officially higher than the Willis Tower in Chicago. The new tallest building in the world is also more than twice as tall as the next-highest office tower in its home city.
In fact, no building in Chicago is higher than the Willis Tower (second only to Dubai's Burj Khalifa as the tallest building in the world). But the difference is that both the Willis Tower and World Trade Center were designed by the same architect, Peter Cook Miller Jr. He also designed the Sears Tower in Chicago, which is second only to the Willis Tower as the tallest building in the Midwest. The Petronas Towers in Kuala Lumpur, Malaysia are also designed by Cook Miller, but they're not attached to any buildings; they stand alone like giant candles.
The Willis Tower was built in 1990 and stands 553 feet high. The World Trade Center was completed four years later in 1994 at a cost of $1 billion and stands 494 feet high. That's bad news for Chicagoans, but good news for New Yorkers. Even though the Willis Tower is still quite the sight to see, it can't hold a candle to its newer counterpart. And with each passing year, it gets harder and harder to tell which is which.
