Surrounded by green fields, 17 kilometres from the capital of Oristano and populated by 4,000 inhabitants, some of whom are the descendants of settlers from the Veneto region, Arborea has the typically ordered structure of fascist cities, with buildings marked by great eclecticism. The straight and parallel avenues are lined with trees, with the two-storey houses in Art Nouveau and Neo-Gothic style being surrounded by greenery. Public buildings overlook the main piazza, in which there is also the parish church of Cristo Redentore (in Tyrolean style). In the town hall there is the Civic Archaeological Collection, a gathering of finds from the Roman necropolis of s'Ungroni.
