CN Tower

CN Tower is 553.33 meters tall and it was completed in 1976. It is the icon of Toronto's skyline and a symbol of Canada, attracting more than two million international visitors annually. So if you are a tourist in Canada, then you are most likely to go up Canada's National Tower to have your Canadian experience. Many locals even haven't been there, as the ticket of $ 23 is quite expensive, so they go when there is an open-house and the ticket cost has been lowered.

Its name "CN" originally referred to Canadian National, the railway company that built the tower.

In 1995, the CN Tower was declared one of the modern Seven Wonders of the World by the American Society of Civil Engineers. It also belongs to the World Federation of Great Towers, where it holds second-place ranking.

But I bet a view from the top of CN Tower at night takes the breath away.
