Although once this centuries-old folk festival was celebrated exclusively on August 24th, the day of Saint Bartholomew, whose church is located at the western entrance to the town, built in the 16th century. In it, on the main altar, there is a statue of that saint made in the Žminj woodcarving workshop, and it is an example of rural baroque in Istria. After mass, in honor of the saint, the people of Žminj gathered around family tables where cabbage was indispensable. Then they would go to a feast, party and dance. Although modernized, Bartulja, which is held today on the last weekend in August, is largely based on centuries-old tradition.
The rich program includes a bicycle race, a race and a soccer tournament, concerts, a livestock fair, shows, a fair of indigenous products, and a car fair.
The streets of Žminj are filled with exhibitors with organic olive oils, wines, cured meat products, sweets, lavender, aronia, immortelle and hemp products, jewelry and numerous decorative items.
Saturday evening is reserved for a big free concert by some of the Croatian stars, and famous musicians perform at the same time on the open stage of the hospitality facility "The bar".
