What makes the CN Tower in Toronto so special?
It is used for TV and radio signals, and visitors can ride a glass elevator to see the city.
The CN Tower was finished in 1976 and stands 1,815 feet tall. For over 30 years it was the tallest free-standing structure in the world. It has a glass floor, and the tower is hit by lightning about 75 times a year.
