The name for circular dry-stone towerlike structures built in Corsica (mainly in the south) during the Middle and Late Bronze Ages. They are typically of Cyclopean masonry and measure 10-15 meters in diameter and 3-7 meters in height; normally a narrow entrance opens into a central corbelled chamber, sometimes with subsidiary niches. The basic plan was often changed to incorporate natural rock formations or extra corridors. The oldest examples are of the early 2nd millennium BC. Although the torri are superficially similar to the Naragi of Sardinia and the Talayots of the Balearic Islands, they are considerably smaller and not effective as defenses or refuges.
