Boulders known as “hunger stones” are reappearing in the Elbe River due to this summer’s drought in Central Europe.
The low water levels in the river that begins in the Czech Republic and crosses Germany into the North Sea have exposed stones on the river bed whose appearances in history used to warn people that hard times were coming.
More than a dozen of the hunger stones, chosen to record low water levels, can now be seen in and near the northern Czech town of Decin, near the German border.
The oldest water mark visible dates to 1616.
That stone is considered the oldest hydrological landmark in Central Europe and bears a chiselled inscription in German that says: “When you see me, cry.”
