Parco Urbano di Cannas di Sotto
Most visitors walk right past this green urban park without realising it conceals one of the oldest necropolises in Sardinia — a haunting hillside riddled with domus de janas rock-cut tombs dating back to around 3700 BC. It is free, walkable from the town centre, and almost entirely crowd-free.
Fairy houses carved in travertine
The Parco Urbano di Cannas di Sotto covers roughly three hectares of green hillside tucked between Corso Iglesias and Via Alghero, right inside the urban fabric of Carbonia. Its centrepiece is an extensive domus de janas necropolis — 'fairy houses' in Sardinian — carved into a travertine hill during the Final Neolithic and early Eneolithic periods, beginning around 3700 BC.
Twenty-six individual grottoes have been identified so far, and their variety is remarkable: some have vertical shaft entrances (the oldest type), others have horizontal openings, and several show evidence of reworking across the fourth and third millennia BC. The monumental Tomb 4, with its large inner chamber, is the highlight of any visit.
Layers of history on one hill
The park is a genuine palimpsest: during Carbonia's mining years in the twentieth century, some of the ancient tombs were repurposed as warehouses, kilns, and animal shelters — a detail that makes the site feel almost impossibly layered. A covered walkway connects the park directly to the Villa Sulcis Archaeological Museum, where finds from the necropolis are displayed, including a full-scale reconstruction of one of the tomb chambers.
On the hilltop, the restored Medau Sa Grutta farmstead hosts temporary exhibitions and cultural events, adding a living dimension to this ancient landscape. The combination of prehistoric archaeology, industrial reuse, and contemporary programming in one small green space is quietly extraordinary.
A perfect short detour
The park is free to visit and open during daylight hours, making it an ideal spontaneous detour between the town centre and the archaeological museum. Go in the late morning when the travertine glows warm and the site is at its most photogenic. Wear sturdy shoes — the hillside paths are uneven.
