 Aliano has its own dialect, "alianese", and the population keep many old traditions.One particular example is that, during "carnevale" (a Catholic festival that takes place a few weeks before Easter) male townspeople, dressed in paper mache masks and hats covered with streamers, wearing long underwear and cow bells, march down the town's main street, throwing flour at gathered crowds and making grunting noises.Some believe that the significance of the custom was to exorcise evil spirits prior to Lent.
