"When you see me, weep"
This is the message that was revealed in a rock in the River Elbe during the dry summer of 2018. It's a famine stone: messages have been carved into river stones in years of famine. That is, a kind of hydrological record of the past and a warning message from the people of that time. The oldest still legible engraving on the Elbe dates back to 1616.
