U Frate è a Sora, Archaeological site near Propriano, France

U Frate è a Sora is an archaeological site with two prehistoric menhirs standing in the Rizzanese plain between Propriano and Sartène in southern Corsica. These upright stones have been recognized as a historical monument and rise notably from the flat landscape.

Prosper Mérimée described the two menhirs for the first time in 1836, during a journey across Corsica; his account appeared in Notes d'un voyage en Corse, published in 1840. He recorded the taller stone at about three metres, the second at 1.60 m, 0.50 m apart, with a third stone lying between them. The menhirs were listed as monuments historiques in 1889.

The names mean "the brother" and "the nun": legend says the two stones are a monk and a nun who fled their convents after succumbing to temptation, and were petrified by God and joined forever. The Corsican song U Frati è a Sora by the group Svegliu d'Isula retells the story, asking who still remembers a forbidden love that defies the offences of time.

The stones are visible directly from the main road between Propriano and Sartène and are easily accessible from the roadside. Plan a brief stop to view the site from different angles, as the flat surroundings offer good sightlines.

The site may contain three stone formations, including a third fallen stone that could be a fragment of the original structure. This additional component offers clues about the original layout of the prehistoric monument.
