The Chapelle St Roch, in the commune, is an ancient oratory annexed to the priory of Tulle in 1318. It was moved to its present location in the village of Boissiaux around 1820.
It is thought to date back to a particularly serious period of rinderpest.
Few saints were as famous in the West as St Roch between the 14th and 17th centuries.
A contemporary of the Black Death, from which he was miraculously cured, he was often the last resort of a humanity decimated by the epidemic that killed almost half the population of Europe.
In St Sornin-Lavolps, he is celebrated every 16 August with a blessing of the flocks. In the past, the priest also blessed a handful of "plague herbs", which were then hung in the stables to prevent the animals from getting sick.
