The church hosts a fresco of Christ sitting on his throne between his mother and St John the Baptist, dating from the 13th century. The legend went that every year, on January 20, the day of St Fabian and Sebastian, dew would fall on the fresco, which lead to many pilgrims coming to Donji Humac. In the church, more than 250 votive offerings gathered over the centuries are on display. Later, the main pilgrimage to Donji Humac moved to July 26, the day of Saint Ana. Today the annual feast of Saint Ana includes a large celebration and the blessing of motor vehicles.
