The Nuraghe of San Pantaleo is located in the Ozieri area, near the Riu Mannu and the road to Chilivani. Its name comes from an ancient church dedicated to San Pantaleo, which no longer exists.

The structure, approximately 5–6 meters high, is partially preserved today but its main features are still recognizable. It originally had two entrances: the southern one has collapsed, while the eastern one is still visible, despite its precarious condition.

Inside, there is a lower chamber connected to a corridor that served as a staircase leading to the upper level. The walls, nearly 3 meters thick, attest to the sturdiness of the structure.

The nuraghe is notable for its use of a particular material: boulders of shell conglomerate, a type of stone that is uncommon in the area.

The site is not managed by the San Michele institution and is located on private property. It can be visited only with the owners' prior consent.
