Timeline of three tallest structures in the world

This is the timeline of the three highest man-made structures in the world.

Overview[edit]

A structure must have been still standing to be considered for that year. Only the height that the structure actually had that particular year is considered for that year, regardless of later modifications. At the points when old structures probably fell, new structures with more certain figures replace them.[citation needed]

When several structures of the same height exists, the oldest is counted as the highest.

The second and third positions are not always definite. Older dates and heights have less evidence backing them. Dates when some of the Egyptian pyramids eroded to their present height are uncertain, as are their original heights.[citation needed]

Land structures are measured from the ground level up (no basements). Off-shore platforms are measured from the sea floor up (the part buried below the sea floor does not count). Only off-shore items constructed in such a way that they would still stand without the support of ocean water are taken into account.[citation needed]

The 1500-metre-tall Magnolia ETLP is excluded from the timeline because this offshore tension-leg oil platform is supported by the water, it is floating, and if the water were removed, the tension in its legs would most certainly cause it to buckle.[citation needed]
