The town lies at the foot of the hilly area and clusters around its Sanctuary of San Firmino, while from the top of a hillock dominates the Parish Church of San Lorenzo, already mentioned in a document in the archiepiscopal archives of Turin in the year 1380.
Already a lordship of the Arduinici, in 1014 Pertusio passed to the episcopate of Vercelli. But before this period, it seems that Pertusio had another lord, the Droy family, once a powerful and noble family group originally from Cuorgné and with jurisdiction in Cuorgné, Valperga, Barbania, Rocca and Levone. They had to bow to the overbearance of the Counts of Canavese: but they continued to call themselves lords of Pertusio. It was then the lordship of the Valperga and San Martino families, who built a stronghold there that has now disappeared, in a place that is still remembered today as ‘Castellazzo’.
At the end of the 14th century, Pertusio took part in the ‘Tuchinaggio’ revolt and in 1391 agreed with the tax authorities of the Count of Savoy by paying a heavy fine. At the beginning of the 18th century, it freed itself entirely from the rule of the nobles.
