CN Tower

                                     1. The CN Tower at 553.33 meters (1,815 ft., 5 inches) was once the tallest building, tower, and freestanding structure, but as of 2010 retains the title of world's tallest tower.

2. Construction on the CN Tower began on February 6, 1973 and wrapped up about 40 months later in June 1976.

3. 1,537 workers toiled five days a week, 24 hours a day to build the CN Tower.

4. The CN Tower was built at an original cost of $63 million.

5. On April 2, 1975, onlookers gazed up in amazement as a giant Erickson Air-crane Silorsky helicopter placed the final piece of the CN Tower's antenna into place, officially making it the world's tallest building.

6. The CN Tower was built to withstand an earthquake of 8.5 on the Richter scale (the Kobe earthquake in 1995 was 7.2 on the Richter scale). The upper reaches of the CN Tower were built to withstand winds up to 418 km/h (260 mph).

7. In 1995, the CN Tower is designated a Wonder of the Modern World by the American Society of Civil Engineers.

8. Lightning strikes the CN Tower an average of 75 times per year. Long copper strips run down the CN Tower togrounding rods buried below ground to prevent damage.

9. The CN Tower dims unnecessary exterior lights during bird migration seasons to prevent bird injuries.

10. The CN Tower is an incredible 2.79 cm (1.1 inches) within plumb, or, true vertical.

11. Six glass-faced elevators travel at 22 km/hour (15 miles/hour) to reach the observation deck in 58 seconds.

12. On a clear day, visitors to the CN Tower's observation deck can see over 160 kilometers (100 miles) -- that's all the way to Niagara Falls and across Lake Ontario to New York State.

13. The CN Tower has a hollow 1200' hexagonal core providing stability and flexibility to the full height tower.

14. The CN Tower's Glass Floor was the first of its kind when it was opened in June 1994. It is 23.8 square meters (256 sq. ft.) of solid glass and 5 times stronger than the required weight-bearing standard for commercial floors. If 14 large hippos could fit in the elevator and get up to the Observation Deck, the Glass Floor could withstand their weight.

15. The 360 Restaurant makes a complete rotation every 72 minutes giving diners a changing view of Toronto more than 1,000 feet below.

CN Tower (Canada National Tower) is one of the most popular tourist attractions in Toronto CN Tower is visited by 2 million people every year. Built in 1976 the tallest building on the planet is a source of pride to all Canadians. The CN Tower was build for more practical reason - the expanding of downtown and the building of skyscrapers started to cause telecommunication problems. The CN tower solved these problems. It is soaring 553 meters (1815 feet) in the sky and has 2 observation decks, 360 rotating restaurant, the Horizons Café and probably the most important of all, theGlass Floor. The Glass floor was specially designed and you will have the most bizarre experience if you dare to step on it. The world will be literary at your feet! The glass is replaced every year and is very safe. Nobody has ever fallen down. It has been said that 14 hippos can sit on it and it will not break, so don’t worry about it. It is located on the lower observation deck at 1,122 feet. The Look out is located on the lower observation deck at 346m (1,136 feet) and one of the 6 high speed elevators takes you there for only 58 seconds.The Sky Pod is the smaller observatory located at 447 meters (1465 feet) and is the World's highest man-made observatory. The view from there is magnificent (on a clear day you can see . On a windy day you can experience a movement because the tower was designed to be flexible and wind resistant. The 360 Restaurant makes one full rotation for 72 minutes. I recommend visiting the restaurant in the evening. The view is spectacular.Every year in October an Annual stair climb in support of the United Way is conducted. The participants climb 1776 steps to the top of CN Tower.How to get to CN Tower : Subway Yonge-University-Spadina to Union Station Opening Hours : Daily form 9am -10 pm, Friday and Saturday from 9am - 10.30 pm

The original plan for the tower envisioned a tripod consisting of three independent cylindrical "pillars" linked at various heights by structural bridges. Had it been built, this design would have been considerably shorter, with the metal antenna located roughly where the concrete section between the main level and the Sky Pod lies today. As the design effort continued, it evolved into the current design with a single continuous hexagonal core to the Sky Pod, with three support legs blended into the hexagon below the main level, forming a large Y-shape structure at the ground level.

The idea for the main level in its current form evolved around this time, but the Sky Pod was not part of the plans until some time later. One engineer in particular felt that visitors would feel the higher observation deck would be worth paying extra for, and the costs in terms of construction were not prohibitive. It was also some time around this point that it was realized that the tower could become the world's tallest structure, and plans were changed to incorporate subtle modifications throughout the structure to this end.

 In August 1974, construction of the main level commenced. Using 45 hydraulic jacks attached to cables strung from a temporary steel crown anchored to the top of the tower, twelve giant steel and wooden bracket forms were slowly raised, ultimately taking about a week to crawl up to their final position. These forms were used to create the brackets that support the main level, as well as a base for the construction of the main level itself. The Sky Pod was built of concrete poured into a wooden frame attached to rebar at the lower level deck, and then reinforced with a large steel compression band around the outside.

Getting to the CN Tower on Foot from Downtown Toronto:

Despite being a hard-to-miss landmark, the actual entrance to the CN Tower can be a little confusing, especially for those with strollers or who need wheelchair access.

At the foot of John Street on the south side of Front Street is a set of stairs that takes you to the entrance of the CN Tower. To the right of those stairs is a wide ramp that leads to both the Rogers Centre and the CN Tower entrance.

For those who need wheelchair access, halfway up the ramp on the left are glass doors that lead to an elevator that takes you down to the CN Tower entrance. These doors are not well marked, so keep your eyes peeled.

By subway, get off at Union Station, exit at Front Street and head west.
