98c.2, 99.2 and 99a.2: The sacred spring of Is Molineddus is located in a valley rich in springs, about 4 km from the village of San Nicolò Gerrei, on the right side of the SS 387 leading to Ballao. From the few pieces of information that Spano was able to gather from the accounts of occasional discoverers, as well as from his own personal observations, his temple consisted of a rectangular building with an entrance on the western side, constructed with large stones laid dry. Behind the building, a spring of water emerged from the rock, collecting in a round well, also made of large stones. Superintendent Taramelli, who explored the area again in 1916, judged that there were “all the elements of a sanctuary of a healing nature, a therapeutic spring and a temple to the healing deity.” (Comune San Nicolò Gerrei)
The sacred spring Su Musuleu, also in the territory of San Nicolò Gerrei, made of sandstone blocks, features a trapezoidal atrium with a paved floor crossed by a channel for water drainage. In the middle of the masonry of the front, the access door to the collection chamber opens, topped by a robust lintel.
In the territory of San Basilio, the remains of the two sacred wells of Bau Crabas are present, located about 150 m apart from each other. The first well is almost entirely buried, while the second is in excellent condition, with an entrance formed by a semi-buried staircase. Cylindrical in shape, it has a diameter of about 2 m and a depth of about 3 m, constructed with stone blocks arranged in horizontal rows. The presence of two sacred wells suggests a cult center of considerable importance.
