Domus de janas di Bruncu Maddeus, Prehistoric tomb structure in Guspini, Italy.

The Domus de janas di Bruncu Maddeus is a rock-cut tomb with a double-oven layout, dated between the 3rd and 2nd millennium BC. It lies on a rocky slope about 70 metres high in the north-west of Guspini, along the Santa Maria di Neapolis road. Its entrance opens to the north-east, and the tomb is still in good condition.

This burial site was created between the 3rd and 2nd millennium BC during the period before the Nuragic culture emerged in Sardinia. During World War II, it was later used as a shelter.

The name "domus de janas" means "house of the fairies" in Sardinian, a folk name given to these rock-cut tombs. The tomb entrance faces northeast, toward the point where the sun sets, an orientation the sources link to the passage from life to death.

The site can be reached by following an unmarked steep path that starts near a stone wall above the road to Santa Maria di Neapolis. Wear sturdy shoes and be cautious if the ground is wet or conditions are poor.

The tomb's entrance opens to the northeast, close to the point where the sun sets, and the structure is described as a "double oven" type. Across the road, on a hill about 80 metres high, stand the nuraghe Bruncu e S'Orcu and a lithic circle a little further downhill.
