Although there is no direct relationship, it is identical to the contemporary Mesopotamian temples and embodies the ‘oriental’ creed of the union between heaven and earth - the sacred areas on top of reliefs were considered the meeting point between man and divinity. The temple of Monte d'Accoddi (from the archaic kodi, ‘stone’), dating back five thousand years, is a ziqqurat that is unique in Europe due to its singularity of architectural types. It was discovered in the mid-20th century, digging into a small hill that appeared to be ‘artificial’, rising up in the middle of a plain. In fact, it was a pyramid altar covered with earth, perhaps dedicated to a female deity, carved in a granite stele alongside the monument. According to legend, it was built by a prince-priest who had fled from the Middle East. It had one very special feature: the ziqqurat is the temple of the Sun, in turn dedicated to the Moon.

The pre-Nuragic sanctuary stands in the centre of Nurra, along the ‘old’ State Highway 131 (heading towards Porto Torres), in the territory of Sassari, eleven kilometres from the capital of the north of the island. The monument played a central role in society of the time, being the culmination of the evolution of a complex developed from the second half of the 4th millennium BC. The altar is the superimposition of two phases, that of the ‘red temple’, in the final Neolithic period (3500-2900 BC), and the following ‘terraced temple’, in the Aeneolithic period (about 2700 BC), as part of the Abealzu-Filigosa culture. In the first phase, several villages of quadrangular huts were part of a ceremonial hub, including a Domus de Janas necropolis and alongside the Santuario, in their original positions, are an elongated menhir (four and a half metres high), an enormous slab with seven holes (perhaps use to tie up victims) and boulders of spheroidal stone, one of five metres in circumference. All the stones served a specific purpose in the sacrificial rituals. At the end of the final Neolithic period, the people of the Ozieri culture built a platform in the shape of a pyramidal trunk, with sides at the base extending 27 metres, above which stood a rectangular room with surfaces plastered and painted in ochre and traces of yellow and black. Of the sacred area remain the floor and remnants of a perimeter wall. Around 2800 BC, the structure of the ‘red temple’, abandoned for about two centuries, was buried under a colossal filling of earth, stones and limestone marlstone, in turn ‘covered’ with large blocks of stone. A new large terraced pyramidal platform was built, with sides longer than the previous one and accessible from a ramp that was forty metres long and thirteen to seven metres wide. The second sanctuary is reminiscent of the ziqqurat with an ‘open-air’ altar. The structure occupies 1,600 square metres, rising up almost six metres (originally perhaps eight). Inside is an unexplored room. Perhaps, as in Mesopotamia, it contains the sacred bed where the ritual of regeneration of life and fertility of the earth was carried out. Around are the remains of a village, where ceramics were found almost intact. To be admired are finds safeguarded in the Sanna archaeological museum, along with a model of the altar in its earliest form. The building retained its religious function for a millennium. At its base, remains of sacred meals and objects used in propitiatory rituals were discovered. The site was abandoned at the beginning of the ancient Bronze Age (1800 BC) and occasionally reused for burials.
