Held since at least 1787, this is the most fun part of the 10-day festival of Saint Helena. On the middle Saturday, wine producing families from the whole province turn out in historic costume to celebrate the grape harvest.

Pulled by horses, donkeys or oxen, carts decorated with grapes, vines, palm fronds, bells, ribbon and tinsel follow a two-hour route through the town, now a suburb of Sardinia’s capital. 

More participants carry tools of their trade, baskets of grapes, and trays of cakes, all to folk music from guitars, accordions and pipes. One cart even had a live grape-treading demonstration on board. The women’s costumes, particularly, are embroidered, multi-layered affairs, outdone only by the decorations on the patient four-legged beasts.

This is a fervent, untouristy celebration of regional traditions, laid on by and for locals. At the end, the carts and their loads are blessed at Sant’Elena basilica in the town centre, and handed out in huge quantities to unwary spectators.
