Denmark: Rabjerg Knude Lighthouse
Now this place was truly spectacular!!! The Rabjerg Knude Lighthouse was built in 1900 on top of Lønstrup Klint, basically a massive sand cliff. However, the strong waves of the sea currents hit this western tip of Denmark the hardest and the sand cliffs erode and retreat on average 1.5m/6ft per year. While the lighthouse was quite far inland originally, it now stands precipitously on the cliff, nearly swallowed by advancing sands and slowly moving toward collapse into the sea. It looks almost like a scene from Western Sahara! The building stopped functioning as a lighthouse and then eventually was completely abandoned due to safety. It was supposed to collapse into the North Sea in 2023, but the decision was made just this summer on August 14, to disassemble and move the entire lighthouse inland.
