Some 5,500 WW2 bombs are discovered in Germany every year and defused, an average of 15 per day.
Discovering bombs from the past is an everyday thing in Germany.
In 2011 it was estimated that over 5,500 unexploded bombs or weapons including shells, grenades, mines, and ammunition from the Second World War that need to be defused are uncovered each year. The daily average is 15, most of them aerial bombs.
They land in fishing nets, are pulled up by excavators during road construction work, or inadvertently removed from fields by farmers.
While no one knows exactly how many still lurk under the ground, we live on top of an estimated more than 100,000 bombs, all of which have the potential to cause catastrophes. Especially affected are the areas which were heavily bombarded during the Second World War- the Ruhr district, Cologne, Hamburg, and Berlin, but also smaller cities like Wesel or Koblenz.
