The wreck of a World War One German submarine is gradually resurfacing on a beach in northern France after decades of being buried in the sand.
Shifting sand off Wissant, near Calais, is exposing the remains of the UC-61 which was stranded there in July 1917.
The crew flooded the vessel and abandoned it and by the 1930s the submarine had largely been buried.
It is now becoming a tourist attraction again, although the local mayor warns it may only be a fleeting visit.
Since December, two sections of the submarine have been visible at low tide about 330ft (100m) from the dunes.
"The wreck is visible briefly every two to three years, depending on the tides and the wind that leads to sand movements, but a good gust of wind and the wreck will disappear again," said Mayor of Wissant Bernard Bracq.
