The CN Tower is a very impressive structure that I was largely unaware of prior to visiting Toronto.  I love large sky scrapers and towers but somehow I had not learned much about one of the tallest structures in the world.  When it was first built, it held the record for the world’s tallest free-standing structure for 32 years, from 1975 until 2007, when it was surpassed by the Burj Khalifa.

I saw a comparison of the Seattle Space Needle to the CN Tower and the CN Tower is over 3 times as tall as the Space Needle!
