Many of Italy’s gunmakers reside in the Val Trompia (Valle Trompia) a 50 km long valley in the Province of Brescia, northern Italy.

The valley contained mineral veins which have been mined for centuries. This encouraged the manufacture of iron weapons. For this reason, under the Venetian from the 15th century, the valley was given a special autonomy and a lighter tax regime.
