Mysteries in the megalithic tombs of Rondossec

The Drei Dolmen von Rondossec, or the Three Dolmens of Rondossec, lie near Plouharnel and Carnac, Morbihan, Brittany. The tombs were explored by the 'Society for the Discovery of the Treasures of Dolmens' in 1849, when two gold chains of Portuguese type from around 2000 BCE were found. Since then, these megalithic monuments have been protected as a Monument historique. The three tombs are far from ordinary. The East Dolmen has a longer chamber and a constricted entrance resembling a flask. The West Dolmen intriguingly lacks its roof slabs, suggesting an additional structure added later. The Middle Dolmen boasts a longer chamber and an enigmatic, smaller annex. The preservation of most ceiling slabs at Rondossec reveals some with rectangular recesses and signs of splitting times, hinting at unknown rituals. Perhaps the greatest mystery at Rondossec is the nearby dolmen named Cosquer.
