List of tallest freestanding structures

This is a list of tallest freestanding structures in the world past and present. To be freestanding a structure must not be supported by guy wires, the sea or other types of auxiliary support. It therefore does not include guyed masts, partially guyed towers and drilling platforms but does include towers, skyscrapers (pinnacle height) and chimneys.

Freestanding structures (past or present) over 350 m

 * indicates a structure that is no longer standing.
 * For all structures the pinnacle height is given, so the height of skyscrapers may be different from the values at List of tallest buildings in the world.
 * Structures under construction are included in the main list if their current height is over 350 m.
