Concentration camp Corropoli (province Teramo) operated from January 1941 to May 1944. The maximum capacity was 150 internees, mostly Slavic and Italian communists as well as Jews.
Letter sent from Corropoli - province Teramo (27.6.42) to Lubljana, free of charge as internee mail, censor mark 15. Very interesting content where the son asks his mother not to write to him in Slovene because the censorship makes the delivery of the mail very late.
