Graz-Karlau Prison

The German word "Dobel" is also written "Tobel", a deep, ravine-like valley or can also be a place and field-name.

Because the castle's name was similar to the nearby "Tobel hunting-lodge" situated in Haselsdorf-Tobelbad, it was renamed as "Karlau", after the archduke.

Until then, condemned prisoners were hanged with short drops, effectively strangling them to death.

Under the British method, Pierrepoint, the Austrian executioner and the two assistants hanged eight young men on September 24, 1946.
