Nuragic holy well

The nuragic holy well is a typical Sardinian hypogean Bronze Age structure for the worship of the waters. Scattered throughout the island, along with the Giants' grave and the megaron temples, they testify to the deep religiosity of the Nuragic populations. These temples were a place of pilgrimage and ceremonies: it is believed that at certain times of year the various nuragic populations of the area gathered together in their vicinity.

Architecture
The oldest temples were built in the style of the nuraghe, with blocks of stone not perfectly squared; over time they were built with a greater accuracy. The most common type is composed of a circular well built with blocks of stone, which was accessed by steps that descended to water level. They are a clear example of the architectural mastery of the nuragics and evidence of their reverence for water sources.

Dating
In the past it was thought that they were built between the eighth and sixth centuries BC; the latest findings, however, have led archaeologists to estimate that the temples date from the time when there was a close relationship between the Mycenaean kingdoms, Crete and Sardinia (around 1300 BC). An almost certain dating comes from recent excavations in the Holy Well of Funtana Coberta, near Ballao, which lack completely Iron Age nuragic ceramics, while there are finds from the Aegean. The Well of Ballao was probably built in the late Bronze Age and abandoned some centuries later.
