Celestinian Forgiveness

The Celestinian Forgiveness (in Italian: "Perdonanza Celestiniana") is a religious and historical annual event held in L'Aquila, Italy, at the end of August. It is a catholic jubilee celebration, established in 1294 by pope Celestine V with his bull "Inter sanctorum solemnia" (also known as "Bull of Pardon" or "Bull of Forgiveness").
Since 2011 the celebration is a "Heritage of Italy for tradition" ("Patrimonio d'Italia per la tradizione") and in 2019 it was inscribed in the UNESCO Representative List of the Intangible Cultural Heritage of Humanity.
