Nuraghe Mannu is a nuragic archaeological site located about 180 metres (590 ft) above sea level overlooking the village of Cala Gonone.

It is located on the east coast of Sardinia, in the middle of the gulf of Orosei, province of Nuoro and the municipality of Dorgali.

The first explorer of the area was Antonio Taramelli who in 1927 denounced the damage that the local people did, caused by them using the stones of the monument for the construction of their homes and streets.

The Nuraghe is a single small tower, is 4.70 meters tall at the highest point and is built with large polyhedral stones of basaltic and trachyte rock.

The structure of the tower is very modest compared to the great extension of the Nuragic village that lies at its feet.
