Researchers have unearthed architectural remains in form of a circular wall measuring 7 metres in diameter and dating back 3000 years in Marcavalle, near Cusco, Peru.
Archaeologists believe that the ring-shaped structure may have been used as a dwelling and a ritual site. Archaeologists link the structure to the pre-Inca Marcavalle culture. A similar wall was discovered as well, believed to have been part of a workshop and a warehouse with signs of successive human occupation. Inside both constructions, the experts found a large number of Marcavalle culture pottery fragments decorated with human and animal faces, obsidian points, stone tools, as well as stone and bone beads.
Among other artefacts discovered at the site are needles and spatulas made out of animal bones; ceremonial figurines; dogs and camelid bone remains; as well as remains of seeds and products like corn and beans. According to the researchers the discovery confirms Marcavalle culture developed at the time when Chavin and Paracas cultures ruled the Ancash and Ica regions, respectively.
