Extending at the foot of
Mount Arcosu and bathed by the
Cagliari pond - known as
Santa Gilla - Capoterra is a centre of about 23,000 inhabitants on the south-western outskirts of the capital of Sardinia. In its vast territory, inhabited since pre-Nuragic times, nature and history intertwine. On the Arcosu there are enchanting and remarkable landscapes, almost four thousand hectares of forest, with a 'heart' of holm oaks and cork oaks, surrounded by Mediterranean scrub, where Sardinian deer and fallow deer roam undisturbed. The park is irrigated by streams and waterfalls. Within the 1300 hectares of the Cagliari lagoon, one of Europe's most important avifauna oases, is the Capoterra pond, where flamingos and black-winged stilts can be observed. Nearby, at
Cuccuru Ibba, there are traces dating back to the Neolithic period: a lithic workshop and circular huts. In various localities, there are ruins from the Nuragic period, necropolis and towers, in particular the
Monti Arrubiu nuraghe. A settlement at
su Loi and a necropolis at Sant'Antonio date back to the Punic period (5th-4th century B.C.). From history to astrophysics: in the hills near the hamlet of
Poggio dei Pini stands the astronomical observatory frequented by international teams of scientists. == Demographics ==
