San Marco Festrival is a traditional Sardinian feste, the most important one, which is a time of excess consumption that helps solidify the social community. Local shepherd families in this predominantly pastoral community offer sheep and oversee cooking them in a gesture of thanks to Providence. Other families offer bread as thanksgiving or for favors desired. Hundreds of people, mostly from Tresnuraghes, but a large number of outsiders as well, eat and drink to satiation together.
