In the framework of the 75th anniversary of the end of the Second World War and the discovery of the horror of the Nazi camps, this book shows the remains of the concentration camps and extermination centres today. The venues, photographed in black-and-white by Luc Mary-Rabine, are now deserted, but they nevertheless indicate what took place there. The silence engenders a train of thought. Nature has somewhat obliterated the horror and re- established its rights. This gives rise to hope: “not ever again”.
