The CN Tower is a 553.3 m-high concrete communications and observation tower located in Downtown Toronto, Ontario, Canada. Built on the former Railway Lands, it was completed in 1976. Its name "CN" originally referred to Canadian National, the railway company that built the tower.
This is my second time in Toronto, and as always this landmark is a must to visit. Except for this time, the lines to go up to the observation deck were one hour long, but once you are at the top you'll enjoy the 360 unobstructed views of the city.
