Complesso nuragico di Palmavera ad Alghero. Rilievo e ricostruzione digitale

The form and architectural characteristics of the nuraghi and the surrounding walls have been decisive in the studies that initially focused on defensive and fortification aspects. From this, theories on Sardinia’s social and economic organization in protohistory developed.However, considering nuraghi only as defensive structures limits the understanding of their complexity. By abandoning a strictly militaristic view and adopting a broader perspective of the term ‘fortress’, their polyvalent function and significance, beyond mere military defence, becomes apparent.In this context, the nuragic complex of Palmavera in Alghero is reinterpreted as an emblematic example of a complex nuraghe, composed of three towers and surrounded by a second concentric wall, known as a structured ‘antemurale’. Contrary to the typical linear masonry, the ‘antemurale’ of Palmavera has a pentagonal shape with towers arranged at its vertices, among which the striking Capanna delle Riunioni.This study proposes a methodology for the documentation and digitalization of the site, divided into two main phases. The first phase is a detailed photogrammetric survey, capable of recording the morphological and dimensional characteristics of the complex. The second phase is based on advanced three-dimensional modelling, which will make it possible not only to represent the site’s current state but also to visualize reconstructive hypotheses based on archaeological theories to explore the original configurations of the nuraghe.
