As the article states "Two photographers ... traveled to France, seeking to rephotograph images captured back then. Getty photographer Peter Macdiarmid and Reuters photographer Chris Helgren gathered archive pictures from the 1944 invasion, tracked down the locations, and photographed them as they appear today."
The above photos here taken from Wikipedia but are the same or similar to the 20 photos covered in the in the article.
If only stones ... and town squares ... doorways, sand dunes ... could talk! (I found Number 14 which relates to the the assault at the cliffs of Pointe du Hoc and Number 20 at the town water fountain rather moving.)
