In a locality then called Belfiore, near Mantua (at the time part of the Curtatone territory, later incorporated into the municipality of Mantua between the late 19th century and the 1940s, as documented in contemporary records), gallows were erected for executions. Between 1851 and 1855, eleven patriots were executed at various sites in the Mantua area.
Among the Martyrs of Belfiore, the following were hanged at Belfiore: Don Enrico Tazzoli, Angelo Scarsellini, Bernardo de Canal, Giovanni Zambelli, and Carlo Poma on 7 December 1852; Tito Speri, Carlo Montanari, and Don Bartolomeo Grazioli on 3 March 1853; and later Pietro Frattini on 19 March 1853 and Pier Fortunato Calvi (on 4 July 1855 at San Giogio).
Not all patriots were hanged: Don Giovanni Grioli was shot on 5 November 1851, while the death sentences of other patriots were commuted to imprisonment.
Belfiore thus became a symbol of Risorgimento martyrdom.
