C N Tower

In 1976, the CN tower in Toronto, Canada, the world's tallest self-supporting structure, opened to the public. At a height of 1815 feet 5 inches it is the tallest free-standing structure in the world. The tower construction began 6 Feb 1973 and was completed 40 months later in 1976. The three legs and central core were built hollow to ensure flexibility in winds, using reinforced concrete and post-tensioned steel. In 1995, the CN Tower was classified as one of the Seven Wonders of the Modern World by the American Society of Civil Engineers.
