CN Tower

The CN Tower is located in Toronto, Canada, Till 2007, CN Tower at a outrageous  height of 553 meters remained the tallest self supporting structure in the world, This title was held since 1975. The newly built skyscrapers were as tall as 250 meters which created problems for signals to be received by radios and televisions.

Soon many companies decided to share a 500 meter tall building to send radio signals around Toronto. A local architect Ned Baldwin, proposed an idea to make the tallest building in the world because then signals cannot be interrupted and will soon become a tourist destination and landmark.

The CN Tower opened to the public on June 26, 1976. The construction costs of approximately CA$63 million were repaid in fifteen years. Canadian National Railway sold the tower prior to taking the company private in 1995, when they decided to divest themselves of all operations not directly related to their core freight shipping businesses.

The CN Tower was practically the only development along Front Street West; it was still possible to see Lake Ontario from the foot of the CN Tower due to the expansive parking lots and lack of development in the area at the time. As the area around the tower was developed, particularly with the completion of the Metro Toronto Convention Center in 1984 and the Sky Dome in 1989 the former Railway Lands were redeveloped and the tower became the center of a newly developing entertainment area.
