Perimeter fences, walls and watchtowers in the Stammlager

There is a high wall that marks the perimeter of the Stammlager which is interrupted by many watch towers with mile upon mile of electrified barbed wire fencing that follows the inside of the perimeter wall as well as dividing the camp into different areas. It is mentioned in a BBC documentary that Rudolf Hoess had to scrounge the barb wire needed to build the Stammlager fences.
