Creating a spectular skyline in downtown Toronto is Canada's most breath-taking, recognizable and celebrated icon. CN Tower stands at a height of 553.33m (1,815 ft., 5 inches), it is Canada’s National Tower, the World's Tallest Building, an important telecommunications hub, and the centre of tourism in Toronto. In the tower is the amazing glass floor and the observation deck. Its a real test of courage to walk across the glass floor at 113 stories above the ground! That dare to walk on air experience, with only 2 1/2 inches of glass holding you 342m in the air lol. Amazingly the glass floor can withstand 4,100 kPa (600 lbs/sq in) or the equivalent to 14 adult hippos.

The tower have a magnificent revolving 360 resturant, that offers a breathtaking spectular veiw, and a romantic evening.If the glass floor isn't enough excitement for you, hit the Arcade or LEGO Racers: The Ride motion simulator ride. The Maple Leaf Cinema also plays a 15 minute film on the construction of the tower 30 years ago.

Amazing isnt it??

The CN Tower has been the world's tallest freestanding structure on land since its opening in 1976.

"The CN Tower, at 553.33 metres (1,815 feet, 5 inches) tall, is the world's tallest freestanding structure on land. It is located in the city of Toronto, Ontario, Canada, and is considered the signature icon of the city; more than two million international visitors are attracted annually to the tower[1]. Guinness World Records has listed the CN Tower as the world's tallest "building" for 31 years[2].

CN originally referred to the Canadian National Railway, but following the railway's decision to divest non-core freight railway assets, prior to the company's privatization in 1995, the CN Tower was transferred to the Canada Lands Company (CLC), a federal Crown corporation responsible for real estate development. Since the citizens of Toronto wished to retain the name CN Tower, the abbreviation CN now officially stands for Canada's National rather than the original Canadian National." - wikipedia.org/wiki/CN_Tower (Click to read more)
