It is said that in the first half of the 19th century, a blacksmith, nicknamed Mazzagat because of his irascible character, had his workshop in vico Canonica. He often quarrelled with his lover Celestina and one day, after yet another argument, he ended up killing her. Mazzagat was arrested, sentenced to life imprisonment and taken to jail. But it is said that the ghost of poor Celestina began to wander around vico Canonica at night with her face covered by a black veil, to cast misfortune and evil eye on the poor unfortunate people. To put an end to all this, one day someone hung a terracotta image of the Madonna on the wall in front of the entrance to what had been Mazzagat's workshop, and it is still visible today. Since then, no one has seen Celestina's ghost.
