In the Middle Ages it was the church of Santa Maria, parish church of Segolay, after the disappearance of the villa of Trexenta; in the nineteenth century it was known, as well as Santa Mariedda (endearment of Mary), also as the church of San Nicola di Bari, according to 19th century historian Vittorio Angius. Nostra Signora della Neve, the oldest church in Senorbì, has almost a thousand years of history, not proven by documents but made up of reconstructions and confusion in the name. It was most likely built in the last quarter of the 13th century in Romanesque style with neatly arranged square sandstone blocks: the original structure appears to have had a semicircular apse and a single nave, covered with wooden trusses. It then underwent various restoration works, including reconstruction of the ceiling and expansion of the nave.
