The very interesting frescoes inside have recently been restored, show a succession of pictorial epochs and propose images of the Saint who died skinned, (note the iconography depicting him with a knife with a long, sharp blade), thus the protector of butchers and linked to the figure of the pig. Note in fact in the beautiful Last Supper on the left wall that instead of the fish in front of the figure of Jesus there is a plate in which one can recognise a piglet. At the end of August, on the 24th, Affi celebrates the 'porsèi' (pigs). Wonderful and luminous is the Virgin and Child depicted on the entrance door, whose existence was unknown, now made visible again thanks to recent restoration work.
