On The Move

This lighthouse was moved 230 feet inland!

Last October, engineers in Denmark moved a lighthouse to prevent it from toppling into the ocean. The Rubjerg Knude Lighthouse was built on a seaside cliff in 1900. Back then, the building was 656 feet away from the edge of the cliff. But over the years, the wind and waves wore away at the cliff. The erosion caused the coastline to recede, bringing it dangerously close to the lighthouse.

To rescue the lighthouse, engineers levered it up onto rolling platforms. The platforms glided along a track, carrying the structure to its new location. There, it was lowered back onto the ground, safe from falling into the ocean.
