In April 1942, concentration camp Mamula was established in the far south of Dalmatia. It was a small camp in a fort on the island Mamula with a capacity of fewer than 500 internees and prisoners, mostly anti-fascists from Croatia, Bosnia and Montenegro.
Mamula fort today.
During the summer of 1943, internees were transferred to other camps - most of them to the Visco near Udine.
30 cent stationery sent from Risano (26.VIII.43) to concentration camp Mamula, censored by Italians and Germans. Since the recipient was already transferred, the stationery was returned to Risano (AL MITTENTE & Retour marks).
