A century on from the Battle of the Somme a photographer has put together a series of photos which show how dramatically different the area is now.

Matt Cardy uncovered a collection of pictures from the Getty archive taken at the time of the battle in North-East France in July 1916.

He then returned to the same places, took new photos from the same viewpoint and digitally merged them.

He says he wanted "to look at the original stuff and try and revisit it."

But it was an ambitious project considering the scale of the battle which lasted 141 days.

"We have done it with a few other significant historic events but with the Somme it was quite an interesting journey because the pictures are mainly of battlefields so it is very hard to locate those now."

The task was undertaken with "a bit of old fashioned detective work," according to Matt.

"You obviously have the caption of the original picture and that might be fairly descriptive. It might tell you the road it was taken on which might be a good start.

"Buildings are the easiest ones because they might still be there but obviously with the battle of the Somme everything was pretty much flattened so that was quite difficult."

There were many photos Matt would have liked to include but was unable to because he couldn't locate the places they were taken.

He explains that the size of landscape made it more challenging: "For example Caterpillar Valley, a big battle area, covers 10 square miles so it's really hard to locate a picture there when there's no point of reference."

Once he had found the locations Matt only took a couple of days to shoot the pictures.

He says that experience felt "quite eerie;" walking in the footsteps of the soldiers who fought in the battle.

"The ones where you've got soldiers marching up a road, there are one or two that you stood there and you thought this is definitely where they would have been a hundred years ago.

"The landscape has changed but to think that you're stood where those guys were marching, in some cases marching to their death, it's quite moving really."
