This memorial is on the back side of the Catholic chapel. It was erected by Polish priests who survived their stay at Dachau. The English version says, "Here in Dachau every third victim was a Pole + one of every two Polish priests was martyred + their holy memory is venerated by their fellow prisoners of the Polish Clergy."
The Carmelite Convent lies just outside the walls of the former camp, with entrance through the former guard tower. Though open to the public, we chose not to visit.
