The tomb is located to the North-East of the Nuraghe Albucciu, about two hundred meters away, along the SS 125 route, on the western edge of the Arzachena plain, in the Gallura hinterland.
The Tomb of the Moru Giants is an example of a megalithic collective burial from the Nuragic Age that is placed on an older funerary monument of the type ad allée couverte to which the exedra is later added. This type is very common in Gallura.
The example of Arzachena consists of a rectangular burial chamber (length about 11.5 m and width about 5.20 m; internal length of the corridor about 9.10 m), attributable to the type of dolmenic corridor with a trilithic pattern, delimited by an internal wall made of plates of varying height fixed vertically in the ground, alternating in some places with dry masonry installed with the superposition of large lithic blocks. This room was intended to house the buried dead, placed inside from above, removing one of the tabular plates (which originally covered it, today only one remains). The funerary corridor is still surrounded and protected by a compact mound of stones and earth that guarantees solid support to its walls, reaching a considerable wall thickness ranging from a minimum of 1.80 m to a maximum of 2.25 m.
The mound in the back is apsidated, and on the front it is contained by a straight façade that prevents it from washing out.
The front part of the monument was characterized by an exedra, that is, a large space in front where the rites were celebrated and characterized, as a rule, by a monumental façade: unfortunately, there are still a series of blocks and small plates that do not allow us to appreciate the original majesty typical of megalithic monuments, so much so that the tomb of Moru appears less impressive than the nearby tombs of the giants of Li Lolghi and Coddu Vecchiu, which, on the other hand, are particularly grandiose in comparison.
The excavation data, however, suggest that the tomb of Moru originally had a different monumentality, namely that the exedra was not characterized by orthostatic slabs fixed in the ground, then removed over time: the compactness of the soil at the base of the remaining façade and its coloring, as well as the discovery of abundant ceramic material placed on the remaining blocks apparently in its original position, suggest that the monument had been built in dry masonry with semi-finished blocks of different sizes, equipped in the center with a large stele, whose presence is suggested by two parallel blocks placed near the entrance to balance it.
Giants' tombs were usually built near a village or a residential settlement with nuraghe whose funerary needs they fulfilled: even the Moru specimen is no exception and is, in fact, located two hundred meters from the Albucciu nuraghe to which, according to scholars, it was relevant.
The monument, dating back to Middle Bronze (XVIII-XVI century BC approximately) in its first construction phase, and to recent Bronze (around the XIII century BC) during the renovation phase, had a continuity of use up to the late Bronze-early Iron Age (about X century BC) but a subsequent phase of attendance is also documented: archaeological excavations conducted in the area have attested evidence from the Punic age, such as a stele engraved with an alphabetical sign (a daleth, to the Fourth letter of the Punic alphabet connected to the cult of the goddess Tanit), and a Punic coin with the head of Tanit and the equine protome (dating back to between 300 and 264 BC). Although no traces of burial from this era were found during archaeological investigations, however, the type of finds suggests that the place had a sacred value.

History of excavations
The Tomb of the Giants, highlighted in 1988 during work to expand the country road that runs along it, was excavated immediately after its discovery.

How to get there
The tomb of Giganti Moru is located in Malchittu, just outside Arzachena. It can be reached by taking the state road 125 Arzachena-Olbia (SS 125). In the area there are also the Nuraghe Albucciu (about 200 meters away) and the temple of Malchittu (1.5 km away).
