Landing scenes in Saving Private Ryan were shot in Ireland.

The Saving Private Ryan Online Encyclopedia
"Sanders and his team then transformed the Irish coast into the German stronghold at Normandy, complete with the defensive Belgian gates and iron hedgehogs. On the beach, they built a "shingle," a low seawall of rocks and sand topped with barbed wire. They also dotted the cliffs with pillboxes, the mini-forts from which the Germans rained down a relentless barrage of gunfire."
I don't know if those bunkers and wires still stand there.
