Ladies and gentlemen - today, I have built the prototype of the CN Tower from Toronto in my native Canada, the 5th tallest building in the world (the tallest building now is Burj Khalifa from Dubai, UAE). For the Main Pod, it took me an estimated 2-3 hours to build. Please excuse the crudity of this LEGO building (I don't have enough correct parts). I've tried my best detailing this. Now let's talk about history - the construction of the CN Tower started in 1972 (40 years ago) and finished in 1976 (36 years ago). On September 12, 2007 (5 years ago), the Burj Khalifa whilst under construction, had beat the CN Tower's record. In August 2011 (1 year ago), the CN Tower opened the EdgeWalk, world's highest full-circle, hands-free walk amusement park. Please rate and comment.
