A farm field remains where German prisoners of war were interned following the D-Day landings in Normandy in Nonant-le-Pin, France, August 24, 3013. On June 6, 1944, allied soldiers descended on the beaches of Normandy for D-Day - an operation that turned the tide of the Second World War against the Nazis, marking the beginning of the end of the conflict. Today, as many around the world prepare to commemorate the 70th anniversary of the landings, pictures of Normandy's now-touristy beaches stand in stark contrast to images taken around the time of the invasion. But while the landscape has changed, the memory of the momentous event lives on. Reuters photographer Chris Helgren compiled a series of archive pictures taken during the 1944 invasion and then went back to the same places, to photograph them as they appear today.
