Between Logudoro and Nurra, surrounded by hills where olive groves, vineyards and artichokes are cultivated, Usini is a village with over four thousand inhabitants in constant demographic growth and based on agriculture. Thanks to its products it has entered the category of città del vino (city of wine): its Vermentino is considered a fine wine and has been awarded international accolades. Bread cooked in a wood-burning stove is a delicacy, as are the pastries, sos germinos, sos biscottos tostos and sas trabeas. In July, Andarinos, the festival of fresh pasta, is celebrated. In Usini, you will rediscover values, activities and traditional know-how: dazzling clothes, music, song and dance are the protagonists of the International Folklore Festival in August.

The village of Usune, mentioned in the condaghi, was made up of the current districts of Usineddu and the Corrau, which is the most ancient, where artefacts from a timeframe covering several millennia (from the Roman age to the Middle Ages) were found. From the second half of the 18th century, new districts developed around the Casteddu, the present-day Piazza Castello (Castle Square), where Casa Diaz stands, a nineteenth century dwelling that, like Casa Derosas, is used for ethnographic exhibitions and as a museum of rural civilization.
