After the decommissioning of the Genoese fortifications, ordered in 1914, Croatian and Serbian prisoners of war were held in the fort during World War I. In 1918, the prison was administered by Francesco Calì, who had been a footballer and first captain of the Italian national football team. From 1958 to 1981, the fort was used as a barracks for the Guardia di Finanza, and subsequently taken over by the Municipality of Genoa, which organized cultural events there in the summer.
