29th June. Following the Mass, the procession, and the novena, the following events take place:
- Sa dittadura de sa bandiera, during which the organizing committee holds a public auction for the right to carry the bandiera (a brocade banner). The winner of the auction earns the privilege of carrying the banner on horseback during the procession and becomes the primary point of reference for the festivities.
- S'Ardia de Santu Perdu, in which the horsemen escort the banner to the forecourt of Saint Mary of the Rose church (Santa Maria della Rosa); after receiving a blessing from the parish priest, the horses set off in a spirited and intense gallop—a race known as s'Ardia.
