Tallest structure ever moved on land
 

In 1958 a 280 metres tall radio mast of the "Europe 1" transmitter in Felsberg-Berus had to be moved a way of 104 metres, otherwise the radiation pattern would have shown in the wrong direction. In order to perform this, the mast was lifted on a special railcar running on two tracks in paralell. On these tracks the mast was slowly moved, whereby the guys had to be adjusted permanently.
The following pictures show the used equipment

I believe, this was the tallest object ever moved on earth.

if you don’t want to read it interestingly it was the titanic in 1911 until fairly recently when a heavier ocean oil rig platform was moved. a desalinization evaporator was the heaviest thing moved on land.

of course on the controversial side ancient astronaut theory would tell us the pyramids were moved around — :D

Moving a guyed mast requires the adjustement of its guy wires during the move, which requires the coordination of multiple winch operations at different sites.
