A giant leap for man kind and it could mean literally that, if you were to fall off this heavenly height.
This man made marvel is the pride of Toronto, Ontario in cool Canada. The CN tower has been heavily endowed with praises and accolades since its inception. It has been recognized as the world’s third tallest structure which is also free standing. It enjoys a second position in the World Federation of Great towers.
In the year 1995 it was bestowed with the honor of being one of the Modern Seven wonders of the world. The CN Tower shares this prestige along with other wonders like the Panama Canal, Itaipu Dam, The Golden gate Bridge, the English Channel, Empire State Building and the North Sea Protection Works.
General CN Tower Facts:
This genius of civil engineering has been celebrated by Canadians and people from the world over who journey to the city of Toronto to relish in the beauty of the creation. The CN tower serves as a massive hub for telecommunications. The majestic tower has on offer world class entertainment, wide array of unique attractions, food, beverages venue and exhibits.

What’s in a name or in an abbreviation?
The CN Tower was built in 1976 by the Canadian National Railways. And originally CN meant the railway company Canadian National which helped construct it. In the year 1995 the tower was transferred to a public company and is managed by the Canada Lands Company. The majority of the people and residents of Canada wanted the tower to retain its name. Hence now the abbreviation CN stands for Canada’s National Tower.
The beginning of a wonder:
The idea of such a tower was conceived as early as 1968. The motive behind the tower was to build a large platform for radio and TV communication and also to demonstrate the strength of Canadian Railway and the Canadian industry. The plans for the structure evolved over the next years and became official in the year 1972.
The crucial engineering team consisted of NCK engineering, Architects of John Andrews, Menkes, Housden architects, Webb, Zerafa, Canron and Foundation Building construction.
The need for the tower:
Toronto at the time was a boom town were large skyscrapers were in plenty. This made broadcasting difficult due to the reflections off these huge buildings especially in the core downtown region. The original plans for the tower consisted of a tripod which has individual cylindrical pillars which were to be linked at different heights by bridges. This would have made the structure smaller. The metal antenna would lie where today lies the concrete section between the Sky pod and the main level.
The approximate cost incurred to build the giant of this structure was dollar sixty three million. It took about forty months to construct the then tallest building in the entire world. The constructed commenced on February 6, 1973. About a year later the mid section of the tower was being worked upon with the start of construction on the tower sphere. And a year on in March 1975 the antenna construction was triggered in rapid succession.
A sky crane helicopter nick named Olga was used to transport and assemble the 36 sections of the antenna in a record time of three and half weeks. The tower was finished on Feb. 22, 1974 and the antenna on April 2, 1975. The tower was opened to the public on June 26, 1976.
Structural CN Tower Facts:
The main section of the CN tower is hollow concrete pillars which are hexagonal in shape. This section consists of the stairwells, six elevators, plumbing and power connections. At the top is a hundred and two meter long metal antenna which is still used to broadcast radio and TV signals.
Visitors can access the main level (Sky pod) and the high Sky Pod (Space deck).
The main level is made up of seven storey, some of them are accessible to the general public. One of the elevators here has a glass floor. A revolving restaurant known as 360 Restaurant is present here.
The restaurant completes a full circle every 72 minutes. The Horizon café below gives a view of 351 meters high. From the second highest observation deck in the world, ‘the sky pod’ on a clear day can throw sights as long away as the Niagara Falls, Lake Simcoe shores or the 100 km away Rochester city in US.
Amazing CN Tower facts:
The metal staircase at the tower has 1776 steps and is the tallest staircase on planet earth. The stairs are not open to the public and are a safety measure. They are opened to the public twice a year for charity fund raisers. The fastest ascent up the stairs was achieved in record 7 minutes and 52 seconds by a police officer Brendan Keenoy in 1989. Jeff Adams who is an Olympic and Paralympics champion climbed up the stairs in a special wheel chair in 2002.
The lighting system of the tower provides elegant night light which illuminated the ‘bubble’ and shoots to the top of the mast of the tower. The light can be seen until 2 am in the morning. The tower changes lights to commemorate major events and holidays.
The intelligent LED system of illumination is cost and energy efficient and can be controlled by a single computer console. A large variety of light effects can be achieved and about 16 million different color shades can be produced on the CN tower.
