For 120 years, the Rubjerg Knude lighthouse has been perched on a sand dune on the northern Danish coast, but coastal erosion from North Sea winds threatened to topple it into the sea.
Now the 720-tonne structure has been saved, in an operation to lift it up and move it 70m (230ft) inland “like skates on rails”.
Within hours, the lighthouse was transported to its new position. (BBC)
