It resulted in six million Jews being murdered, as well as other people considered inferior by Nazis.

The Holocaust was over by 1945. However, there are still physical reminders of it in Europe.

Marc Wilson is now an accomplished photographer who has traveled to 130 different locations across 20 countries for six years. 

For his book “A Wounded Landscape” he has collected 360 photographs that document the various 40,000 Nazi-occupied sites between 1939-1945.

Wilson examined areas where Jews were murdered along with gay people, learning disabled individuals, Roma, Jehovah’s Witnesses and communists. He also studied more than three millions Soviet prisoner of war.

Following the discovery of smells from mass graves in neighboring villages, in 1942, corpses were burnt in open-air ovens.

He added, “These places persist today across these countries. These sites created a path to genocide. They destroyed communities and ghettos as well, and also transit camps for workers, camps for internment, camps for labour, camps for labor, camps of subsistence, camps that were concentration camps for extermination and other camps.

They are interconnected by their surroundings and the journeys they make between them. These sites saw mass killings on an individual basis and massacres at a large scale. The numbers were almost unimaginable.

These are places where life and death were decided, but also these are locations of hope, survival, and memory.

Ben Barkow was the former director of London’s Wiener Holocaust Library. He stated: “The Wiener Library offers many opportunities for artistic responses to Holocaust. I can say unambiguously Marc’s work has been among the most beautiful and sensitive we’ve seen in many decades.”

Concentration and extermination camps of the Nazis: These factories of death were used to kill millions 

Auschwitz–Birkenau near Oswiecim (in what was then occupied Poland).

Auschwitz–Birkenau was an extermination and concentration camp that the Nazis used in World War Two.

This camp was situated in Nazi-occupied Poland and consisted of three major sites.

Auschwitz I, the original concentration camp, Auschwitz II-Birkenau, a combined concentration and extermination camp and Auschwitz III–Monowitz, a labour camp, with a further 45 satellite sites.

Auschwitz, a camp for extermination used by the Nazis of Poland to massacre more than 1 million Jews, was known as Auschwitz.

Birkenau played a significant role in the Nazis’ Final Solution to Europe’s Jewish Problem.

An estimated 1.3 million people were sent to Auschwitz-Birkenau, of whom at least 1.1 million died – around 90 percent of which were Jews.

It has been operated since 1947 as Auschwitz–Birkenau State Museum. Unesco designated it a World Heritage Site in 1979.

Treblinka near a similar-named village, in Nazi-occupied Poland outside Warsaw

Treblinka was a camp where Jews were given forced labor, but not at Treblinka. Nearly all Jews that were brought there were killed immediately.

Few, mostly young and strong men, survived immediate death. They were instead given maintenance jobs.

Treblinka had the second highest death rate after Auschwitz. Between July 1942 and October 1943, Treblinka saw between 700,000. and 900,000. Jews murdered in the gas chambers. This was just 15 months.

After an uprising that saw 200 prisoners escape, exterminations were stopped at the camp. Despite the fact that around half were murdered within a few hours, 70 prisoners survived to the end.

Belzec, located close to the station with the same name under Nazi-occupied Poland

Belzec existed from March 1942 through June 1943. The camp was constructed as an extermination center as part Operation Reinhard.

There were many victims, including Polish, German and Ukrainian Jews. In total, around 600,000 people were murdered.

Sobibor is located near the same village in Nazi-occupied Poland

Sobibor is named for its nearest train station. Here, Jews could get off extremely packed trains, unknowing what their fate would be. 

In three gas chambers, Jews from Poland and France were killed by deadly fumes from large petrol engines taken from tanks. 

The camp was home to an estimated 200 000 people. Estimates range from 200,000 to 250,000. 

Sobibor is now the fourth-worst extermination camp in terms number of deaths, behind Treblinka, Belzec, and Auschwitz. 

About 50 miles was the distance from Brest-on-the-Bug to this camp. The official German name of the camp was SS-Sonderkommando Sobibor.

The heroic escape of 600 prisoners on October 14th 1943 saw them all break the camp’s perimeter wall.

Only 50 managed to avoid capture. It’s not clear how many made it into allies territory.

Chelmno, also known as Kulmhof in Nazi-occupied Poland

Chelmno was one of the first camps constructed by Nazi Germany specifically to exterminate. 

From December 1941 through April 1943, it was then reactivated from June 1944 to January 1945. 

There were between 152,000 to 200,000 victims, almost all of them Jews.  

Majdanek was also called Lublin and built near the city of Lublin.

Majdanek originally meant for forced labor, but it was later converted to an extermination camp by 1942. 

There were seven gas chambers and a wooden gallow where victims could be hanged.

There were approximately 130,000 victims. 

MailOnline was told by Mr Wilson that he had “wanted” (or perhaps not realising the need) to create a work on the Holocaust over the past 20 years, since he began taking photos. 

He added: “It’s something I thought was important to talk about, share and to begin conversation about. To be truthful, I never believed I was capable of taking the photos required for a topic like this or talking about it properly.

“I didn’t have the right voice nor visual language. In 2015 after finishing my last book, The Last Stand I finally felt that perhaps I did. The visual language was what I had hoped to be able to speak about the tragedy.

“A calm enough voice but insistent to speak about history. It is something that should not only be spoken about, but also must be remembered, ignored or worse denied.

In his second statement, he said that he had some ideas for how the book would be made and the topics to cover. He took them with him when he went to South East France.

This all changed when his second late-afternoon photoshoot was over. He covered his head in a dark cloth and looked through my large format camera’s ground glass screen. It felt “completely and completely wrong” to him. It was wrong.

Wilson said, “My first thought was to photograph these places from afar, in the larger landscape surrounding them as I have done previous work. But these images that I made were not objective, incorrect, cold or calculated. 

“But I was aware of what I had done and I didn’t think about it. That morning, I went to the old internment camp and crossed over the border of the mass artworks that had surrounded it. Finally, I entered the space.

“And there, after spending two hours searching for the Barrack ‘K12’, the ex-children’s barrack I finally found my voice. You can see the fading paint on the walls that were painted by children more than 70 years ago. The roof tiles had cracked and there was some grass around it.

“I was given what to do. Tell the children’s stories. One of them. There are many more. These stories could be retold by countless others: 1,000, 1000, or a million.

“I worked there and returned to the UK and had many conversations with people, showing them my work, sharing it, having discussions and planning the next steps.

When asked what it was like to travel to these places, Wilson replied: “Throughout this six-year period of work, I was always aware of how fortunate I was to have this opportunity to visit these destinations. It was my choice whether to work in the area for several weeks or return home.

“So, I allowed them to wash over me. The locations as well as the details of the events I was told by someone there during wartime in our conversations.

“Each place I visit will remain with me, but it’s not possible for me to work successfully on this topic, or this type, at a distance.

These places could be remembered today or lost forever. You can mark the site with a plaque, or build a shopping mall with multiplexes and McDonalds.

“But every one of the more than 150 locations we visited has a story, with its own stories. Nearly all of them are full of tragedy and horror.”

He stated that while he was writing the book, he tried to avoid putting one place over another. Also, not giving any story more significance than another.

Wilson said, “Some places have made a lasting impression on me more than others.” It could be because of the closeness of a location to an incident shared with me personally by one or more of my 22 family members, or simply for how I felt about that particular place.

“In some places it was a faint shadow of a painting on the wall. In another location, in the Kulmhof extermination camps in Rzuchowski Forest, Poland it was human bone fragments seeingping from the soil.

The ashes of murdered prisoner bodies, which were burned to the ground and then crushed as a way to conceal what happened. Every one of these individuals, whether a mother, father or child who was murdered, grandparent, brother, sister, or other family member, is just like us.

He stated that it took him “some time” to be brave enough to speak with Holocaust survivors.

Wilson stated, “But each meeting, every one-hour or four-hour, and in some cases two-day conversation, left me an indelible imprint.” They were kind and compassionate, gentle and strong. 

When asked by one of the survivors if there was something that stood out, Wilson replied: “I spent days listening to these people in different languages. I took in every word and glance. I didn’t ask specific questions, but just listened. 

“Hearing them share what they had to say with me and sharing what they wish the world to learn. Rita (96) spoke to Rita in December 2017.

A gas chamber at Auschwitz in Nazi-occupied Poland. The SS and police are estimated to have deported at least 1.3million people to the Auschwitz camp complex between 1940 and 1945. Of these, around 1.1 million people were murdered

Auschwitz, Nazi-occupied Poland. Police and the SS are believed to have sent at least 1.3 million persons to Auschwitz between 1940-1945. Around 1.1 Million people were killed among these.

“After telling me her story, she was deported from her village and placed in an internment camp. She then went on to a series of slave labor camps. Her family was murdered. Finally, there was the Death March in Stuthoff concentration camp. The death march saw her group being put on a barge at the Baltic Sea. They were left without food and water and left to die.

Rita Weiss was a woman who Wilson met in Tel Aviv (Israel) and told Wilson: “In April 1945, they ordered us to leave the camp. We were walking, not on foot. There wasn’t a train or bus. The Death March.

“We arrived at the sea, and there were barsges. We were afraid to go under the water. A barge with prisoners from Norway, Poland, Greece… After one day and one night we did not know what to do. We must learn to swim, said one man.

“We didn’t know the country or whereabouts we were. We just wanted to get out there and swim, so that we could. Either we would drown in the ocean or die from being on the boat, It was imperative that I survived.
