Now a small, chilling museum, Via Tasso 145 was the headquarters of the German SS during the Nazi occupation of Rome (1943–44). Members of the Resistance were interrogated, tortured and imprisoned in the cells and you can still see graffiti scrawled on the walls by condemned prisoners.
Exhibits, which include photos, documents and improvised weapons, chart the events of the occupation, covering the persecution of the Jews, the underground resistance and the Fosse Ardeatina massacre.
