Menhir di Genna Prunas

Menhir di Genna Prunas is an upright basalt stone column located near Guspini in Sardinia. The stone stands about 1.70 meters tall, measures roughly 60 centimeters wide at its base, and tapers toward a rounded top.

This stone dates to the Ozieri culture of the fourth millennium BCE and represents an early form of monumental construction in the region. It stands along kilometer 99 of the SS126 road, marking a significant period in Sardinia's past.

Cup marks cover the stone's surface on all sides, suggesting that people once gathered here for rituals or to observe the sky. The marks indicate this was more than just a boundary stone, but a place of spiritual importance.

The menhir sits on private agricultural land and is under the supervision of the local archaeological authority, so checking ahead is worthwhile. Wear sturdy shoes when visiting, as the path to reach it crosses uneven farming ground.

The stone bears roughly 30 cup marks, one of the highest concentrations of such markings on any Sardinian menhir. This unusual density makes it a puzzling object for researchers still working to understand its purpose.
