Another fascinating article on Wikipedia:
“This is a list of tallest structures in the world, past and present of any type. Most of the tallest structures are television broadcasting masts, followed by a mix of the taller tower-type structures (like the CN Tower) and the taller high rise buildings (like the Sears Tower). Scattered among these are other structures including oil platforms, electrical towers, bridge towers, etc.”
Of particular interest to me was the Warsaw radio mast, which was the world’s tallest structure at 646.38 meters and collapsed in 1991 due to an error when carrying out maintenance on its guy ropes.
