A German World War I submarine has resurfaced just off the coast of a French beach near Calais.
The wreck of the incredible vessel has become visible for residents of Wissant, thanks to a combination of shifting sand and tide levels.
The submarine, which was used primarily to lay mines, was sunk by its crew and abandoned after it ran aground in the middle of the night in July 1917.
But it is not the first time the UC-61 has been exposed.
Pieces of the vessel have appeared in the past - usually every two to three years, depending on weather and sea conditions.
