It is the only place of worship in Sardinia dedicated to the Spanish martyr, born in 123 AD and beheaded when she was only 16 years old. A sandstone slab, engraved in 1686, informs about the discovery of a stone in which the dates 1280 and 1583 were carved: the first should date back to the year of construction and the other to a remodeling, in which the loggia was probably built as a shelter for devotees and pilgrims. In 1966 side chapels were added, which together with the nave form a Latin cross plan. Particular is the devotion to the saint, who is venerated twice a year, on the Tuesday after Easter and on July 17, when the ancient simulacrum kept in the parish is dressed in a red robe, harnessed with jewels and loaded onto a wagon pulled by a yoke of oxen to be led in procession to her little church, accompanied by the singing of the rosary in Sardinian and de “is gòcius.”
