- The "Perdonanza Celestiniana"
(The Pardoning of Celestine V):
On 28 August a historical procession goes
through the town carrying the Pardon Bull,
an original document kept in the Municipial
Tower, up to the Basilica of St Maria di
Collemaggio, where the "Porta Santa"
(the Holy Pardon Door)is opened by a Cardinal
as an "Apostolic Legate".
The Pardon Bull grants anyone entering the
Basilica of St Maria di Collemaggio, confessed
and truly repented, from vespers on 28 August
to vespers on 29 August, absolution from
L'Aquila is, together with Rome, the only
town in the world enjoying the privilege
to open the Holy Door every year.
On the days before the "Perdonanza
Celestiniana", performances, concerts,
art and handicraft exhibitions and several
cultural and entertainment activities are
organized in the town.
