Museums agricultural center located in the valley of the rio Cixerri. Mentioned as Musej in the registers of Pisan annuities (1323) and as Musey in a document of the Codex Diplomaticus Sardiniae, later, in the Middle Ages and until the 17th century, it was called Villa di Prato, belonging first to the giudicato of Calari and from 1257 to the Pisan family of Della Gherardesca, once owners of the castle of Acquafredda, in the territory of Siliqua, in the center of the valley. Coinciding with the arrival of the Jesuits, the name changed: perhaps a reading of the name Iesum backwards or a corruption of the word moisè, a settlement of Jews planted here, or again from the Semitic word mosià (task). It was the Society of Jesus, to whom the village was bequeathed in 1607 by the feudal lord (and protector of the Jesuits) Monserrato, son of Elena Nicolau, a noted humanist and judge of the Royal Audience, who spearheaded the establishment of the new center. A late Baroque church, equipped with valuable works, including a silver-rolled astylar cross, and the convent of St. Ignatius of Loyola, founding patron of the Society of Jesus, celebrated in late July, were built. Houses sprang up around it. The Jesuits, in addition to devoting themselves to apostolate and cultural activities, also gave new impetus to agriculture, particularly wheat crops and vineyards, and animal husbandry, for which in the 18th century the town was one of the most renowned in the island. Hence the strong agro-pastoral tradition of the present Museums. The fertility of the land has always attracted peoples to the area. Human presence in Antiquity is evidenced by nuraghi and Punic and Roman remains, particularly a site near the ancient village Arruinalis, where foundations of ancient buildings are found. The historic center of the village is characterized by its earthen buildings; of particular interest is the large barn “su cungiau de domu” built entirely of earthen construction. Of Museums some artisans who have resumed the production of unfired bricks.
