Its five domus de Janas are secluded, located on the steep slope of a trachyte hill, and can be accessed through hidden entrances: secret passageways branch out from them, into the depths of the rocky elevation, with a total of 18 funeral cells. The pre-Nuragic necropolis of sas Arzolas de Goi, dating back to the Ozieri culture (3200-2800 BC) and in use until the Eneolithic period (2400-1800 BC), is located a few hundred metres from Nughedu Santa Vittoria, a small municipality in the Barigadu region, 50 kilometres from Oristano, that looks out onto the splendid scenery of Lake Omodeo. In the tombs, which are multicellular, with corridor, anterooms, main room and lateral spaces, lateral spaces, there are prehistoric artistic expressions, like effigies carved in the stone depicting the deities invoked by the Neolithic populations. Four tombs are grouped together on the hillside, while the fifth is about twenty metres away on the front of a body of rock. The entrance door of tomb 1 appears to be warning you, with a raised carving of a bull’s head, complete with ears and horns. The Bull is the male God, venerated in Neolithic times as a symbol of fertility and fecundity along with the Mother Goddess, also portrayed in sas Arzolas. You will also find the taurine effigy on a pillar inside the funeral cell. On the walls of the passages, you will notice mysterious ochre decorations – the symbol of life being renewed through blood – colouring architectural elements like pillars, pilasters, cornices and small niches with a deep red colour. Tomb 2 extends longitudinally and consists of two cells preceded by an anteroom and secondary rooms. Here, the traces of red paint becomes more intense, almost warming the environment. In the middle of the floor of the first cell, you will notice a hearth. The entrance to the second cell is adorned by a cornice. The room attached to it has straight walls embellished with red paint, crosses carved into them and the roof of a hut inhabited ‘by the living’ depicted on the rock. The third hypogeum is rectangular: you will notice two ‘beds’ raised from the floor, located near other small cells. In the last tomb, which was dug twenty metres southeast of here, you will also see traces of ochre and taurine effigies.
After the underground visit, you can carry on with your archaeological and artistic tour. Contemporary with sas Arzolas de Goi, there are the Neolithic domus de Janas of s’Angrone. Next, there is the protonuraghe of su Casteddu, around which there are huts and a megalithic structure reminiscent of dolmens and Tombs of Giants. In the old town centre of Nughedu, at the foot of mount Santa Vittoria and of the centuries-old wood of Assai, the sixteenth-century parish church of San Giacomo stands out between the ‘Spanish-style’ houses. In the countryside, you will find the Novenario di San Basilio Magno, consisting of a late Gothic-Catalan-style church and a portico surrounded by fifteen muristenes (modest pilgrim accommodation).
