With a Neolithic site, one Nuraghe and two churches, this archaeological-artistic complex is enclosed in the space of a few tens of meters. Around the Nuraghe Arresi arose the first inhabited nucleus of Sant'Anna Arresi, a village in the lower Sulcis area whose name combines its prehistoric origin to the patron saint, to whom are dedicated ‘old’ and new parish. The Nuraghe, dating from the 15th-14th century BC (Middle Bronze Age), stands between the two churches and was built on an older settlement, inhabited in the late Neolithic and the early Aeneolithic periods (3200-2600 BC). Completing the prehistoric picture within the village are two Nuragic fountains, to the east and west of the monument. It is a case of cultural superimposition: various spiritual ‘forts’ came in succession within the town for millennia.
