Danish lighthouse put on wheels to move it away from eroding sea
Rubjerg Knude used to be 200 metres away from coast before sand shifting and erosion
A 120-year-old lighthouse has been put on wheels and rails to move it away from the North Sea, which has been eroding the coastline of north-western Denmark.
When the 23-metre (75ft) Rubjerg Knude lighthouse was first lit in 1900, it was roughly 200 metres from the coast; now it is about only six.
