Arzachena culture

The Arzachena culture was a late Neolithic culture (4th-3rd millennium BC) of the northeastern part of Sardinia (Gallura) and part of southern Corsica, it take his name from the Sardinian town of Arzachena.

This cultural aspect is best known for having built important megalithic structures, among the oldest in the two islands, suchs as the characteristics "circular graves" and menhir. Both the funerary architecture and the material culture show similarities with contemporary contexts of Catalonia, Languedoc, Provence and Corsica.

Differently from the people of the contemporary Ozieri culture of the rest of Sardinia, the people of the Arzachena culture were organized in an aristocratic and individualistic society focused on pastoralism rather than agriculture. The aristocratic groups buried their dead in megalithic monuments in the shape of a circle, with a central chamber containing a single individual, while in the rest of the island the Ozieri people buried their dead in collective hypogeum tombs called Domus de Janas.
