CN Tower - Wonders of the World. In 1995, the CN Tower was classified as one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.
The CN Tower shares this designation with the Itaipu Dam on the Brazil/Paraguay border, the Golden Gate Bridge in San Francisco, the Panama Canal, the Chunnel under the English Channel, the North Sea Protection Works off the European coast, and the Empire State Building.
Since the Tower opened, Canadians and tourists from around the world have made the trip to Toronto to celebrate this marvel of civil engineering. Besides serving as a telecommunications hub, the Tower provides world-class entertainment and a wide range of unique attractions and exhibits venues.
