Photograph taken at the Mauthausen Camp: A photograph shows a brick wall with two large and thick metal doors in the middle of it. Large rolling metal trays are coming out of the doors. Two smaller metal doors are at the bottom of the wall. A long metal pole with a rounded handle is leaning against the wall. The bricks on the wall are discolored and darkened above and below the doors. Where the doors are open, darkened bricks can be seen inside. © 2012 Image Quest The image depicts which area of a death camp?
