CN Tower (Canada’s National Tower), the thin needle piercing Toronto’s skyline, is the world’s tallest free-standing structure on land, standing at 553.33 meters or 1,815 feet tall. It was built originally as a radio and television transmission tower, the largest construction project in Canadian history. Completed in 1976, the tower has attained unimaginably successful as a hugely profitable tourist attraction. Today, this dizzy, extravagant monument built by the Canadian National Railway is the very symbol of Toronto.
The CN Tower features two areas where tourists can visit – the main deck at 330 meters or 1,100 feet and the Sky Pod at 447 meters or 1,465 feet high. A six-speed elevator that travels 22 kilometers/hour (or 15 miles/hour) takes you up to both levels.
The main deck is home to the glass floor, which you can walk across and see-through the glass below – you’ll get an idea of how high up from the ground you are, which causes some people to experience acrophobia. The main deck is also where the outdoor observation deck called the “Look out” is located. You’ll also find a café called Horizons Café and a fine-dining restaurant called 360; this latter restaurant rotates a full revolution every 72 minutes, the average dining time.
The Sky Pod is the world’s highest public observation deck. Up here, you can get a 360 degree view of Toronto and the surrounding Lake Ontario region, and see about 100 to 120 kilometers (60-75 miles) away. In fact, on a clear day, you can see vague outlines of Rochester, New York and the Niagara Falls. |
