Palazzo Benintendi, today Palazzo Scalori, stands at 10 Via Chiassi and is closely linked to the events surrounding the Belfiore Conspiracy, recalled by a plaque above the entrance. In 1850, a group of Mantuan patriots gathered here for the first time, meeting secretly in the study of engineer Attilio Mori, inside the residence of Livio Benintendi, to discuss plans for freeing Italy from foreign domination. Around 20 people took part, including Don Enrico Tazzoli, Achille Sacchi and Giovanni Chiassi. Tazzoli became one of the main organisers of the revolutionary committee. Chiassi, then just 25, would die 16 years later at the Battle of Bezzecca, while Sacchi, a democrat and Garibaldian, lived nearby in the street that bears his name. The conspirators decided to contact Giuseppe Mazzini, who was in exile in London. Giuseppe Finzi was tasked with establishing the connection, and the Mantua committee was asked to distribute and sell the bond certificates issued by Mazzini to finance the revolutionary cause, and circulate pamphlets and posters. Don Tazzoli kept a secret register of all financial activities, encoded using a system based on the Pater Noster. The register listed the committees accountable to the Mantua treasury, subscribers’ names, and members entrusted with special assignments. During a search of Tazzoli’s home, the authorities discovered one of the loan files and arrested him. The subsequent confessions, accusations, and the deciphering of the coded register by Viennese experts led to the arrest of many other patriots. The conspiracy was effectively dismantled.
