Perosa Argentina (French: Pérouse) is a comune (municipality) in the Metropolitan City of Turin in the Italian region Piedmont, located about 40km (30miles) northwest of Turin, in the val Chisone.The population of the village is 3061 (30 June 2023).
It is located in the Val Chisone area and it is part of the Mountain Community of Valleys Chisone and Germanasca, which has been part of the Mountain Community of Pinerolo since 2010. Currently reconstituted under the name of the Mountain Union of Valleys Chisone and Germanasca, it is a group of municipalities that includes Fenestrelle, Inverso Pinasca, Massello, Perrero, Pinasca, Pomaretto, Porte, Prali, Pramollo, Roure, Salza di Pinerolo, San Germano Chisone, Usseaux e Villar Perosa.
The term "Perosa" comes from the word peira, that means "stone" in Occitan, referring to a cobblestone road. Instead, the following term "Argentina" tell us about the ancient silver mine on the slopes of Bocciarda Mountain: we also find this information looking at the town coat of arms, where we can indeed see three silver stones on a black wallpaper with the quote Dant fructus lapides, which means "stones bear fruits". This second part of the name was added on 11 April 1862, one year after the birth of the Kingdom of Italy.
Perosa is mentioned for the first time in a document dated September 8, 1064, in which Countess Adelaide of Savoy (1092–1154), widow of Oddone of Savoy, granted to the Benedictine Abbey of S. Maria di Pinerolo, founded by her, all rights of feudal sovereignty and land ownership over the people and things of the valleys of Perosa and S. Martino. The reference is to "Petrosa", indicating the nature of the mountain landscape, and Podium Odonis, named after Adelaide's husband, to designate the hill of Perosa Alta.
The small village was watched over by a castle and in its center stood the church, already dedicated to St. Genesius.
At Adelaide's death, Tommaso I of Savoy succeeded in regaining possession of the ancient family territories, included Pinerolo.At the end of the 13th century, the Waldensian presence in the valleys must have constituted a matter far from negligible, as evidenced by the decision to send an inquisitor to Perosa in 1297. However, threats, fines, confiscation of property and torture did not yield the expected results. So much so that, ninety years later, in 1387, the inquisitor Antonio di Settimo lamented that many inhabitants not only adhered to heresy but were even spreading it in the neighboring valleys.During this period of time (1301–1418), Acaja princes, cadet branch of the House of Savoy, extended their domains to almost all of Piedmont territory using arms and marriages.
Unfortunately, this troubled border land disputed between the Dauphiné and the House of Savoy suffered tragically because of this long and tough rivalry. The population paid a very high price in term of human lives, owing to wars, epidemics and misery, all consequences of bad international policy choices.
Between XVI and XVII century, the situations in this tormented land was very complex: comings and goings of different armies, alternation of governors, 38 years of French dominance with Francis I and the triumphal entry of Emmanuel Philibert in Pinerolo on the 1st January 1575; the establishment in the valley of Capuchin missions, aimed at curbing the spread of the Reformed religion, took place following the persecutions by Charles Emmanuel I against the Waldensian population. The Waldensians were confined to lands on the right side of the river Chisone and were forced, in part, to emigrate far away. This led to the founding of the village of Perouse in Germany, within the municipality of Rutesheim.
During such tumultuous events, Perosa was besieged twice by French troops: in 1592 by Lesdiguières, who descended into the valley to repel ambitious Savoyard attempts to occupy the Val Pragelato (belonging to France until Bec Dauphin, as an inheritance of the Dauphins), and in 1630 by Cardinal Richelieu himself, determined to seize Monferrato and counteract the dynastic claims of Charles Emmanuel I on those lands. These are about anather 70 years of French dominance, for the second time.
The strategic position of Perosa's fortifications gave them great importance during both periods of peace and war. Unfortunately, nowadays only few remains are left: a fortified village since the time of the abbots, later expanded by the Acaja family and equipped with "good and high walls" by the Savoy dukes, a significant stronghold during the second French domination, in 1696 Perosa was returned to the House of Savoy, but on the condition that its citadel be completely demolished.The same fate had befallen to the Saint John's fort in 1601, built just 4 years before on the rock called "Bec Dauphin", the ancient border between Dauphiné and the House of Savoy (the ruin we can see nowadays was part of a French redoubt).
Perosa, after returning to the House of Savoy, subjected once again French dominance in 1796, and then with the Restoration, became part of the Kingdom of Sardinia until the Unification of Italy.
