Cappella di Saint-Roch e Saint-Clair

High in the hamlet of Bosset, above the vineyards of Issogne, a small chapel keeps the memory of one of the seventeenth century's darkest years. Built after the plague of 1629–30 and dedicated to two plague-adjacent saints, it still draws the village together each sixteenth of August for mass, blessed bread and an old-fashioned auction.

Why it matters

This chapel is Issogne's memorial in stone to the great Italian plague of 1629–30 — the epidemic remembered in history as part of the Manzoni years — and one of the many votive buildings raised across the peninsula in thanksgiving for survival. Its double dedication is deliberate: Roch was the great plague intercessor of European Christianity, and the pairing recorded on the facade with the Virgin made the building a civic act of gratitude rather than a private foundation. Unusually, the sources specify its promoter: the local municipal administration of the time, which made the chapel a collective vow of the community. Unlike most plague chapels, it never became a ruin of folk memory; its patronal feast is celebrated to this day with rites — blessed bread, and an incanto, an auction of donated goods for the chapel's benefit — that are as much social institution as devotion.

What to notice

The facade carries the chapel's message in paint: the two titular saints and the Virgin are depicted together, a compact votive image of the community's plea and thanksgiving. Bosset sits at the top of its village, overlooking the Dora Baltea valley and the landscape around the castle below. Recent conservation has treated the building, its interior and exterior frescoes, and its paintings. The patronal feast on 16 August ends with blessed bread and an auction of offerings, a custom through which the community has organised solidarity since the seventeenth century.

Context and history

The plague years 1629–30 swept through the duchies of northern Italy, and valley communities answered survival with building. At Bosset, the chapel was erected after the epidemic on the initiative of the local municipal administration of the era — a rare documented case of a communal, rather than seigneurial or familial, votive foundation at Issogne, complementing the Challant-era chapel at the village entrance and the hillside chapel of Visey. The choice of saints follows the pattern of plague devotion: Roch, the pilgrimage saint who ministered to plague victims, paired here with Clair (San Clarus in local usage), whose cult is attested in the Valle d'Aosta. The painted facade presenting both saints with the Virgin served a population that encountered the building's meaning before entering it. The community's attachment shows in the continuity of the feast: 16 August, Roch's day, closes with blessed bread and an incanto auction whose proceeds benefit the chapel itself, a funding mechanism that has evidently helped carry the building to its present restoration campaign.
