Introduction
Toronto, Ontario Canada what comes to mind? Well Google search images for Toronto, Canada and your first result will show a city skyline with an abnormal large tower just standing in the middle. This “abnormally large tower” is the CN Tower, measuring 1,815 feet. The CN Tower is labeled as the world’s tallest self-supporting building. While in comparison Chicago’s Sears Tower stands a mere 1,707, more than one-hundred feet less than the CN Tower. Not only is the CN Tower Toronto’s largest city attraction but it is home to the 360, an award-winning restaurant that is accompanied by the world’s highest wine cellar. The 360 completes a revolution every 72 minutes. The CN Tower is not only an engineering marvel, but also its beauty and lasting impression has put Toronto on the map, internationally.

Comparative Study
The Leaning Tower of Pisa captures history at its finest. This mammoth tower has long and old beginnings. Construction began August 9, 1173 by Bonanno Pisano. The foundation consists of marble, lime, and stones. In 1178, the tower was just three stories tall when construction halted for unknown reasons. The tower continues again in 1272, led by Giovanni Di Simone. Once again, construction stops only six years after it began and the tower already has a lean of about one degree. For the final time construction began in 1360 with a 1.6-degree lean. Engineers made efforts at the time, by adding six steps from the seventh cornice up to the bell chamber’s floor, while only having four on the north side. Construction was officially completed about in the year 1370.

Conclusion
The CN Tower and the Leaning Tower of Pisa are similar yet different. First, the CN Tower is modern and can be recognized throughout the world instantly. While the Leaning Tower of Pisa has the same affect, except it’s not so modern, it is a national landmark another quality that these two towers share. The engineers of the CN Tower did an amazing job, and produced perfection. But on the other hand the Leaning Tower of Pisa, not so much. However, without these mistakes and if they would have built this structure on solid ground it may not be the landmark it has became, and not obtained its worldwide fame. Because who wants to look at some tower that stands straight up in the air, you want to see something different and unique, and the Leaning Tower of Pisa does this. These two landmarks will remain forever-constant focal points and tourist destinations of their respective cities.
