One of the Gallura area’s most characteristic Nuragic landmarks is a sacred well where water worship rituals were performed. Pozzo Sacro di Sa Testa (The Holy Well of Sa Testa). It dates to between 15th and 13th centuries BCE and sits just outside of the town of Olbia. It is just under 18 metres long and made of granite, trachyte and schist cut into blocks that were then carefully finished. The external part is reminiscent of a door and symbolizes the gateway that separates the world of the dead from that of the living. The shrine has a circular courtyard, a vestibule, a small hallway between the courtyard and the well, and steps that lead down to the water at the bottom.
