it was populated since prehistory
(the first human settlements date
back to 6.000 - 5.000 B.C.), Sardinia
never elaborated a unitary association
form. The trace of the settlement
is therefore extremely fragmentary,
as lots of little villages throughout
the island witness, villages which
are expression of a civil-social order
organized in communities and tribal
groups of modest entity.
The age of the nuragic civilization was a period of indipendente, but also of relative isolation from the big cultural movements in the Mediterranean area. The Nuraghe with its peculiar architectural structure is the most representative sign of that past.
A typical character of Sardinian archeology is the disposition of the monuments and architectural works, spread all over the countryside, making up an harmonious whole with the natural environment.
The Nuraghi as well as other evidences of the past, such as Domus de Janas, holy wells and temples, the giants tombs, the big stones fixed in then ground (betili or menhir of the megalithic architecture)
make of Sardinia a kind of open-air museum. These signs are very frequent. On the whole island there are, in fact, about 7000 Nuraghi and hundreds of archeological monuments.
