It’s everywhere.
I live in the Netherlands, near Rotterdam, the center of which was bombed by the Germans in 1940. The remainders of the Atlantikwall are just twenty miles away. My old school was commandeered by the German military. Unexploded ordnance is still occasionally being detected and cleared. Walking in a park last week, I saw an old Panther tank, now a memorial to the fighting that once took place there. I even work for a government institution that supports WWII victims.
Yes, it’s everywhere. From the names of streets, to the silence of the graveyards, to the stories and memories of elderly people.
