The necropolis of Anghelu Ruju is a pre-Nuragic archaeological site located north of the city of Alghero, Province of Sassari, Sardinia.

Following these findings, the archaeologist Antonio Taramelli carried out, the following year, the first excavations of the site discovering ten domus de janas.

Within the many chambers are numerous finds of grave goods (vases, statuettes of the hypothesized "mother goddess", weapons, necklace beads etc.

Furthermore, finds of flint tools, mace-heads, arrowheads, axes and beads suggest a culture which emphasized hunting and warrior prowess; whereas silver rings, copper daggers appearing to originate from Spain, an awl which likely was from southern France, a copper ring of an eastern European style, and an axe which was from the British Isles indicate that Sardinia was heavily involved in this time period with a great deal of international trade.

The Sardinians, for their part, were known to possess an ample amount of valuable obsidian from Monte Arci, a long-dormant volcano on the island.
