Goli Otok is considered to be the only gulag to ever exist in socialist Yugoslavia. It was built in 1948, three years after the end of World War II and shortly prior to the cold war. Located on a barren islet, Goli Otok was Marshal Tito’s most notorious prison. The islet was previously used as a prison in the Austro-Hungarian war during WWI for housing Russian prisoners of war. Tours of the prison are available from travel agencies in the resort islands of Rab and Krk.
