It's hard to overstate the perfection of the Nuragic water temple of Santa Cristina—the Sardinian Archaeologist, Giovanni Lilliu, puts it best: "It represents the peak of water temple architecture. Its proportions are so balanced..., its geometric composition so exact..., so rational..., that it doesn't seem possible...for it to have been built around the year 1000 BC."
The Nuragic civilization lived on the island of Sardina, present day Italy from approximately 1800 B.C. until 200 B.C. They were a Neolithic culture who built stone dwellings and sacred wells such as this one, Nuragic Sanctuary of Santa Cristina. Many sacred Nuragic wells can be found on Sardina but Santa Cristina is the most intact. It is believed that it was used in rituals pertaining to a cult of water.
