Were there concentration camps in Fascist Italy? When were they made?

Apart from obviously the of the British and soldiers captured in Africa will certainly have been camps for Yugoslav and Greek soldiers. But I think that overall they housed a very small number. The most serious is that during the of Salò near Trieste there a camp for Jews known as Risiera di san Saba. However, it not managed by personnel of the Reoublica Sociale if I remember correctly the area of Trieste after the invasion of by the Germans had been incorporated directly into the Reich and a Governorate excluded from any control by the Social Republic.
