CBC Tower (Mont-Carmel)

The CBC Tower, also known as the WesTower Transmission Tower, was a 331.4-metre-high (1, 087 ft) guyed mast (now 326.7-metre-high (1, 072 ft) after its reconstruction) for FM and TV transmission located atop Mont-Carmel near Shawinigan, Quebec, Canada. The tower was built in 1972 and it served for several decades as Quebec's primary CBC transmission point and also served several radio and television stations for the Trois-Rivières market. In 2001, the tower was destroyed in a tragic but bizarre set of circumstances when a single-prop plane crashed into the tower necessitating its demolition and reconstruction. At the time it was the tallest known explosives demolition of a structure in recorded history.
