The small Martinetto polygon is what remains of the complex that the municipality, from 1883, entrusted to the National Shooting Society. In 1934, it ended its sporting use because a law assigned civilian shooting ranges to the state. After September 8, 1943, it was chosen by the Italian Social Republic as a place for the execution of death sentences: more than sixty partisans and resistance fighters found death there, among them, eight members of the Piedmont Regional Military Committee, who were shot on April 5, 1944.
After the war, the polygon was dismantled and moved to the Basse di Stura, while the Martinetto was recognized as being of national interest and used as a memorial: surrounded by a small garden, created in 1967, the execution enclosure remains with a plaque commemorating the victims.
On April 5 each year, a ceremony is held there commemorating the shooting of the eight members of the first Piedmont Regional Military Committee-Franco Balbis, Quinto Bevilacqua, Giulio Biglieri, Paolo Braccini, Errico Giachino, Eusebio Giambone, Massimo Montano, and Giuseppe Perotti.
