During construction along the railroad in Naarden-Bussum, North Holland workers dug up some bombs, which according to ProRail, are most probably from WWII. I can’t imagine from wat other war they could be from, since the Dutch weren’t really involved in WWI. I say this as someone who recommends reading The Art of Staying Neutral: The Netherlands in the First World War, 1914-1918. When the Dutch mention ‘the war’, they always mean WWII.
The bombs will be exploded somewhere safe, as it is done here when they find bombs, which is quite regularly. It’s not sure whether this will delay the works along the railway or not, which are already planned to go on for three weeks.
Here are some of our past stories related to finding bombs and grenades:
