Dolmen di Motorra

On a basalt plateau in the territory of Dorgali, eight upright slabs, one enormous capstone and a ring of eleven stones preserve one of Sardinia's rare corridor dolmens. Built by Ozieri communities in the Final Neolithic and reused for centuries, it still shows its closing stone, its passage and the tumulus ring that once held the burial mound.

Why it matters

Sardinia preserves many megalithic tombs, but true corridor dolmens are uncommon, and the regional tourism authority presents Motorra as one of the island's rare examples of the type. Its oldest burials belong to the Ozieri culture of the Final Neolithic, between roughly 3200 and 2800 BC, and the last documented use falls around 1800 to 1600 BC, so a single small chamber served communities across more than a thousand years. The monument sits in open farmland on a basalt upland at 214 metres above sea level in the territory of Dorgali. Its essential architecture remains legible: capstone, passage, closing slab and the stone ring that once carried the burial mound.

What to notice

Eight rectangular basalt slabs, carefully finished on their inner faces, enclose a small hexagonal chamber roofed by a single irregular pentagonal capstone measuring about 3.00 by 2.90 metres. The opening faces south-southwest and still keeps its fragmentary closing stone in place; behind it a short corridor — four orthostats once spanned by three slabs, now displaced — led down below the chamber level. An elliptical peristalith of 4.90 by 4.10 metres, with eleven slabs still standing, once supported the mound of earth and small stones that covered the whole tomb. On the western side, three slabs roughly two metres long are driven vertically into the ground, knife-like; explanations range from a shelter wall against the weather to the remains of a second, outer ring. The scant remains of a nuraghe of the same name stand on the plateau nearby.

Context and history

The dolmen entered the scholarly literature through Giovanni Lilliu, whose study appeared in Studi Sardi in 1966, and through Maria Luisa Ferrarese Ceruti's contribution to the 1980 volume Dorgali. Documenti archeologici. Much of the recovered material came from clandestine digging before proper excavation, yet it still frames the tomb's long story. Four ceramic fragments of the Ozieri culture are the oldest and most significant finds, joined by two chalcedony beads, a bone amulet carved as a tiny human head just 1.9 centimetres high, and a small three-holed sandstone archer's wristguard. Ceramics of the Bonnanaro culture document the final phase of use near the start of the second millennium BC, and the Dorgali archaeological museum notes San Michele-style pottery of the Final Neolithic among the evidence that dates this class of monument. Motorra forms part of the broader megalithic landscape of Dorgali's plateau.
