Five thousand years ago (circa 3400-2850 BC) where the location of “Su Coddu” is today, arose one of the largest villages in the whole Mediterranean of Nuragic period. In 1981, during the development works of the area, some archaeological finds were undiscovered. This discovery gave the start to numerous excavation works that highlighted the complexity of the settlement, of which unfortunately only a small part remains visible today between via Nenni and via De Gasperi. The numerous materials found are kept at the former Caserma cavalleggeri in Selargius.

The choice made by man to settle in this area was not accidental but linked to the morphological characteristics of the territory, which seemed very different from what it is today. A stream ran through oaks, olive trees, fig trees and wild vines and the pond was a few kilometers away from the pond of Molentargius. Mother Nature provided much of the resources useful for the subsistence of the village.

While men were engaged in hunting and fishing, women took care of picking mollusks and wild fruits. Over time the activities became more and more complex, which included the breeding, the cultivation of cereals, the weaving, the metallurgy, the production of ceramics and the processing of stone and obsidian. Most of the objects found were made for practical use (jugs, pots, pestles, scrapers, spearheads, needles) but there were also those created with a purely ornamental purpose such as shell necklaces and pendants of various materials, or likely linked to the sacred like the statues of the Mother Goddess. One of the most important findings is undoubtedly a terracotta crucible, which testifies to the on-site melting of metals. Life inside the village took place mainly in the open spaces where hearths, bids for the waste, and water wells were available to the community. The huts, at least 120 of them, mostly circular in shape, were covered by a roof made using reeds, timber and mud, had several functions. Some huts were used as houses, others reserved for the storage of supplies or used as a workplace for grinding cereals, cooking food and processing obsidian. The absence of defensive or control structures makes us think that the inhabitants of Su Coddu lived together peacefully with those of the nearby village of Terramaini, sharing the same natural resources and having social interaction.
