Argimusco, Archaeological site in Montalbano Elicona, Italy

Argimusco is an archaeological site near Montalbano Elicona where large sandstone boulders stand at around 1200 meters (3,900 feet) elevation within the Malabotta Forest Nature Reserve. These rocks form geometric and organic shapes set against the Sicilian sky.

No traces of prehistoric habitation — pottery, tools or bones — have been found around the stones, so archaeologists attribute their shapes to wind erosion of quartz sandstone rather than human work. Hypotheses of astronomical alignments and a ritual or calendrical function were put forward by astrophysicist Andrea Orlando, while Paul Devins, who considers parts of the rocks man-made, dates them to the late Middle Ages or later. In June 2015 the SB Research Group of the University of Trieste measured acoustic resonances among the rocks.

Local tradition calls the rocks dolmens and menhirs raised by a prehistoric people, and names individual stones such as "Virgin in Prayer", "The Monk", "The Male Face" and "The Eagle". Since 2012 the Festival di Archeoastronomia 'Pietre&Stelle' has linked the plateau with the sky; Franco Battiato was a guest of honour in 2014 and later used the site in the video for his song Torneremo ancora.

The plateau lies above 1,000 m on the northern edge of the Bosco di Malabotta, between the Tyrrhenian Sea and the Alcantara valley, and is split between Montalbano Elicona, Tripi and Roccella Valdemone. The two tall stones of Portella Cerasa and the sun-marked rock at Portella Zilla are the landmarks to aim for. Weather on the open grass changes fast; carry wind and rain protection.

The names given to the rocks — "Virgin in Prayer", "The Monk", "The Male Face" and "The Eagle" — come from popular tradition, not from archaeology. No pottery, tools or bones have been found around them, so archaeologists attribute the shapes to wind erosion rather than human carving.
